Many of these cannot be read from a desk. 784 of the open entries are marked needs archive scans: the ciphertext, or the key material that would unlock it, is not online, so nothing can be deciphered until the archive digitises it or someone photographs it in the reading room. They are listed because a request to the archive, or a visit, is the first step.

Before starting on an entry, read its known and open lines on its page and the open pull requests below. Work that has landed is folded into both lists at each rebuild; work still in a pull request is not. If a number you were given is not in the table, it has left the catalogue: look it up. The lists and the pull requests are recomputed at every rebuild; each entry’s known and open lines were written by hand and carry the day they were checked (all of them on 21 Oct 2026 at the latest full pass).
What is solved or known so far
198 catalogue numbers have been deciphered, explained or found in print and have left the open list (the list; every write-up is on the write-ups page). 65 of the entries still open have pieces already deciphered or identified.

- no. 410 Conde de Sabugosa → Queen Amélia, code telegram of 13 May 1903 (Lisbon → Paris), no decode 13 May 1903 — 27 Oct 2026 (WAINUT, PR #105; targets/sabugosa1910/): the unit holds telegrams of 13 May 1903, 24 Apr 1904 and 21 and 24 May 1910. The last three were read from decodes of the time in the same unit (m0008, m0005+m0004, m0009) and are written up; pairing gave 52 values of a one-part code. This one (m0014, 43 groups) has no decode; 6 groups have a value.
- no. 443 Unknown correspondent, cipher letter, 31 July 1662 (Sanguszko archive) 31 Jul 1662 — DECODE R7513 (status N/A, cipher type unknown, private ciphertext, uploaded by the Archiwum Narodowe w Krakowie 2023; no key or decryption file on the records). Not in repo (known.py on each R-number: no hits).
- no. 474 Comenius → Andreas Klobusiczky, cipher passage of 24 May 1655 (Rákóczi archive) 24 May 1655 — 4 Aug 1655 sentence deciphered in print (Szilágyi 1890 p. 393; Patera 1892 p. 182); key = Rákóczi envoys' table, MHH XXIII p. 740. The 24 May passage does not decipher with that table, shifts, keyword ciphers, or as a simple substitution of Latin (annealing with matched control); no decipherment in MHH, Szilágyi 1890 or Patera. See targets/comenius1655/.
- no. 657 Bernstorff (German Embassy Washington), second code text on the State Department cable of 11 Jan 1917 (groups 147-576), unread 11 Jan 1917 — 27 Oct 2026 (WAINUT, PR #115; targets/bernstorff1917/): groups 0-146 are Bernstorff's telegram No. 205 of 10 Jan 1917, printed by Bernstorff (1920, pp. 325-326) and in Official German Documents II p. 1017; aligning them gave 82 groups of a two-part four-figure code with prefix figures (not 13040; probably 0075 [?]). Written up. The memorandum on frames 0769-0775 is not the plaintext. This entry is now the second text, 430 groups in the same code, unread. 2 Nov 2026 (section 10 of the notes): the code is Code 7500 of Friedman and Mendelsohn 1938 by route and structure (this cable not named there); their nine sibling telegrams were not found on the digitised reels; catalogue 635 keeps no groups; the text is not in Bernstorff 1920 or Official German Documents. A crib needs PA AA, TNA HW 7/ADM 137, or State Department files on site.
- no. 669 Soviet and German cipher radiograms of 1921 (Moscow ↔ Berlin, Stockholm, Christiania, Kharkov), intercepted at Constantinople by the US High Commission and never deciphered 1921 — Unblocked 27 Oct 2026 (NARA slice L, research/nara_triage_l/): the purport list (naId 87657409) led to the 861.00 file, which is filmed on M316 and digitised as RG 64 copies; all nine 1921 rolls fetched and the OCR read. The High Commission could not decipher the traffic and the Department records no decipherment; the War Department (MI-8) received parallel copies (RG 457 6707N). Some of the same Soviet traffic may have been read by GC&CS (HW 12, 1921) and the German side is Auswärtiges Amt traffic; neither has been checked. Distinct from 710 (Chicherin → Sukhanov 1918). Worked 2 Nov 2026. Letter traffic in the file is a columnar transposition with a key per telegram: two deciphered and removed from this entry's open work (targets/lejava1921/, targets/voikov1921/); others in targets/voikov1921b/, targets/stomoniakov1921/. Figure traffic, the core of this entry, still unread: no group value recovered (targets/kopp1921/, targets/karakhan1921/). HW 12 and RG 457 still unchecked.
- no. 841 Philip IV to Juan de Velasco y la Cueva, conde de Siruela, ambassador in Genoa: despatch entirely in cipher (PARES title "Minuta de despacho cifrada") 20 Nov 1638 — Read in part by Brice Dudout (28 Oct 2026, reported, not yet checked here): about 87-88 % by sense (884 words; 61 unresolved, 57 restored, 8 probable), key K3k from the genes1638 family, validated on a letter not used for training. Below the 95 % bar; the unread part is the nomenclator.
- no. 1468 Federal (Huertista) army telegrams "en clave" in Gen. Guillermo Rubio Navarrete's papers: Lampazos, Monterrey, Laredo, Zacatecas Jul 1913 - May 1914 (and Jan 1918) — CEHM: "EN CLAVE", no translation; a few siblings carry summaries (1.29.9-30, 2.41.18-41: railway repaired to Gutiérrez north of Fresnillo). Key sheets of the Secretaría de Guerra filed with them. Narrowed 30 Oct 2026: three telegrams in Clave núm. 109 (1.30.16-49, 2.41.9-41, 2.41.13-41) were read by Brice Dudout (write-up rubio1913); the other pieces use other tables and are unread.
- no. 1566 Este ducal ciphers: Ercole II → Cornelio Bentivoglio (1559), Claudio Ariosto (1559), Alfonso II → Claudio Ariosto (1576) 28 May 1559; 15 Jul 1559; 14 Apr 1576 — Letter of 14 Apr 1576 (Alfonso II d'Este, cc. 76-77) read ciphertext-only by WAINUT (targets/alfonso1576/; narrow). The 1559 letter to Bentivoglio (cc. 50-51) is a transcription job from a contemporary gloss, read in part (targets/ercole1559/), and Ariosto's c. 1 (15 Jul 1559) is in another system, not solved. Original status: Estense catalogue (Lodovico Media Library / Estense Digital Library): Lettera cifrata. | Lettera parzialmente cifrata. No decipherment mentioned in the record.

- no. 1614 Swedish letters to Axel Oxenstierna, June 1633, code numbers glossed in part (R4338-R4341) June 1633 — Bremen letters of 1631 (R4330-R4331) deciphered in full here, key recovered from the interlinear glosses (riksarkivet1628). R4282 key recovered ciphertext-only by George Lasry (decode4282, PR #33). R4306 deciphered in part by George Lasry with CTTS and Opus 5.5, 17 Oct 2026 (sweden4306, PR #42); four code values open. R4336-R4337 (Rusdorff, London, Feb 1625) key recovered ciphertext-only by George Lasry with CTTS and Claude Opus 5.5, 21 Oct 2026 (rusdorff1625, PR #72); codes 628 and 701 open.

- no. 1560 Charles V → Ferrante Gonzaga (governor of Milan): the numeric letter of 11 Aug 1542 and an undated cipher letter, still unread 11 Aug 1542; undated — Narrowed 3 Nov 2026. The five sign letters of 1549 are written up as gonzaga1549 (docs/gonzaga1549.html); 15 Jul 1549 and 1 Jul 1552 were deciphered at the time on leaves in the file. Left open: 11 Aug 1542, a numeric cipher in single digits with stacked superscripts, no key found, not the 1548 numeric key; undated cc. 131-132, not in the Karl V to Gonzaga listing and not located online.
- no. 1462 Maderista junta at El Paso: telegrams "texto en clave" that the catalogue leaves undeciphered, among hundreds deciphered at the time Mar - May 1911 (and 1914) — CEHM: "TEXTO EN CLAVE" with no decipherment, against dozens of sibling records "TEXTO EN CLAVE Y DESCIFRADO" in the same legajos; CMXV.18.1795.1 is a typed transcription of the decipherments of 66 coded telegrams (Jan-May 1911) and CMXV.16.1557.1 holds 21 manuscript keys ("clave Madero, letras más frecuentes", "clave G.A.", "clave de los reyistas", División del Norte alfabeto).
- no. 450 Düben to Queen Lovisa Ulrika, system B ('Chiffer n:o 2'), 1764 5 Oct - 31 Dec 1764 — 2,072 groups pooled, 291 distinct; no decipherment on the leaf. The annealer fails its control at this size (targets/duben1764).
- no. 465 Conrad Biermann's copybook, 1675: letters outside key K55 1675-1676 — Letters to Lilienkron, Gioë, Schröder, Reetz, Lindenow, Klingenberg, Lincker and Lente, in other number families (targets/biermann1675).
- no. 1556 Cardinal Ercole Gonzaga → Ferrante Gonzaga, two letters with cipher (one sheet entirely in cipher) undated (1539-1557) — Estense catalogue: cipher, no decipherment noted. Deciphered siblings in the same sub-file: cc. 88-92 (28 Jun 1544), 93-98 (2 Jul 1544, Rome avvisi of 22 Jun in cipher and deciphered), 102-105 (4 Jul 1544), 106-110 (10 Jul 1544), all 'in cifra e decifrati'.
- no. 1561 Prince/King Philip (II) → Ferrante Gonzaga, Spanish letters partly in cipher; six without decipherment, two deciphered 25 Jun 1546 - 16 Jun 1563 — Estense catalogue (Lodovico Media Library / Estense Digital Library): In spagnolo. Lettera parzialmente cifrata, decifrata alla c. 11. | In spagnolo. Lettera parzialmente cifrata, decifrata alla c. 14r. | In spagnolo. Lettera parzialmente cifrata. | In spagnolo. Lettera parzialmente cifrata. Luogo di incerta lettura. No decipherment mentioned in the record. Not on DECODE, not in the repo (known.py (your repo + DECODE + Cryptoole list) on the names: no hits). Undeciphered (as catalogued): 25 Jun 1546, 4 Aug 1548, 24 Nov 1551 (two letters), 14 Mar 1553, 16 Jun 1563 (Ferrante I died 1557: recipient to be checked). Deciphered: 23 May 1547 (clear at c. 11), 8 Mar 1549 (clear at c. 14r).
- no. 1578 Jan Klemens Branicki → Antoni Potocki, voivode of Bełz: letter mostly in cipher, catalogued unsolved May 1757 (dateline on the letter; the day is not read at this resolution) — Catalogue: 'List w większej części szyfrowany nierozwiązany'. Scan 2 viewed: clear French opening, then a neat run of lower-case letters and some digits with no interlinear decipherment.
- no. 1616 Lovisa Ulrika correspondence, system A: 6 Mar 1764 and the glossed letter of 15 Nov 1765 6 Mar 1764; 15 Nov 1765 — 6 Mar 1764 (641 groups) with no gloss, and the 11 unglossed lines of 15 Nov 1765. The gloss on 36 of 47 lines fixes no single table: the values vary through the text.
- no. 2112 William Perwich? → Sir William Temple: letter from Paris with "a long passage in code" 7 Jun 1669 — Finding aid: "Letter includes a long passage in code." The name is cut by a page break in the PDF; the neighbours are Perwich items. File 1410 in the same series is "Mr. Perwich's Cypher" (c. 1668-72), endorsed by Blathwayt. Perwich's 1670 transposition paragraph to Arlington was only solved in 2025 (Biermann and Lasry; Brown; TNA report, per cryptiana unsolved.htm). This letter a year earlier may share the system.
- no. 681 Richard Taylor's telegram letter-books 1865 (NARA RG 109 ch. II vols. 196, 11, 10): the cipher telegrams still unread and not in the Official Records Nov 1864 - Apr 1865 — Narrowed 3 Nov 2026: read here or printed in OR are listed in folio_note; open are about ten telegrams of Feb-Apr 1865; held keys not yet run on them.
- no. 885 Sigismund August of Poland, Frater Georg Martinuzzi and Queen Isabella to Ibrahim Pasha: ciphered copies with a Latin exemplar 1 Jun - 22 Jul 1548 — AIS: the cipher copies are not described as deciphered, but each letter has a Latin exemplar of the same text. Malvezzi's covering letters are edited in Austro-Turcica 1541-1552 (7-4-9: pp. 276-278); the edition may not print the enclosures. Not on DECODE; not in the repo (known.py: '7-4-5' no hits). 2 Nov 2026: in progress in targets/ibrahim1548/: 7-4-4 f. 29 transcribed and decoded (the cipher spells the exemplar); f. 28, 7-4-5 and 7-4-9 not yet.
- no. 1468 Federal (Huertista) army telegrams "en clave" in Gen. Guillermo Rubio Navarrete's papers: Lampazos, Monterrey, Laredo, Zacatecas Jul 1913 - May 1914 (and Jan 1918) — CEHM: "EN CLAVE", no translation; a few siblings carry summaries (1.29.9-30, 2.41.18-41: railway repaired to Gutiérrez north of Fresnillo). Key sheets of the Secretaría de Guerra filed with them. Narrowed 30 Oct 2026: three telegrams in Clave núm. 109 (1.30.16-49, 2.41.9-41, 2.41.13-41) were read by Brice Dudout (write-up rubio1913); the other pieces use other tables and are unread.
- no. 1470 Cipher telegrams to Setembrino de Carvalho, federal commander in Ceará (Juazeiro sedition) 10 Mar - 20 May 1914 — CPDOC summary 'Telegramas cifrados a Setembrino de Carvalho'. Image of the first telegram viewed 28 Oct 2026: letter cipher, no decipherment on the sheet. Cribs in the same digitised fonds: FSC cont 1914.10.07/2 (two War Ministry cipher words glossed) and FSC pce 1914.02.19/2 (typed clear copies of Vespasiano's telegrams to Setembrino, one acknowledging 'mais dois cifrados'). Not on DECODE, not in the repo. Vetted 28 Oct 2026: Vigenère, 8-letter key restarted per word; key MFTDBSJV rebuilt from the pencil decipherment on pagfis 1319 reads the Mar-Apr telegrams; 10 Mar (LETCARIV, garbled) and 20 May (about 10-letter key) broke ciphertext-only in minutes. Verdict key_lookup: a small, quick reading, worth doing as a target (key recovered from adjacent plaintext / ciphertext-only), not a catalogue entry.
- no. 1523 Luis López Méndez (London) → Simón Bolívar, letter on the Gambier expedition, part in a secret key 29 Jan 1819 (London) — AGN description: López Méndez reports the sailing of the schooner Gambier (Capt. Peter Paxtor) with men, arms and powder, that the East India Company ships were not bought and the loan not raised, and 'otras informaciones se hallan consignadas bajo el código de una clave secreta'. No decipherment mentioned. Not on DECODE; known.py: López Méndez no hits. Vetted 28 Oct 2026 on the scans: the cipher is a letter table with superscript row digits (1-7), 15 words in a clear letter. Not printed in the O'Leary volumes on archive.org. Most of it was recovered from context during vetting: López Méndez was jailed five months and freed on bail; MacGregor 'ha causado un perjuicio indecible a nuestra causa'; MacGregor plans to go to Santafé (sample file research/latam_vetting/1523_sample.txt).
- no. 1526 Jefatura civil y militar del Amazonas (Gen. Amadeo Rodríguez Vergara): cipher telegrams on the Leticia crisis and a possible conflict with Ecuador Aug-Sept 1932 — AGN description names cipher telegrams; the same fonds holds the key description (GARV..1.1.4, "la criptografía y descripción de claves para enviar comunicaciones", 1931) and more cipher telegrams in GARV..2.2.1 (June 1932, pliego de clave for the Presidency), GARV..2.3.1 (Oct 1932, "Comunicaciones a Presidencia en clave con traducción", radio-operator correspondence on transmission keys), GARV..2.3.2 (Oct 1932: report of Major Velasco en clave, telegrams en clave from the War Minister and Presidency) and GARV..2.4.1 (Nov 1932, "Telegramas en clave con traducción adjunta"). So the fonds has key, ciphertexts and translations, all imaged. Not on DECODE; known.py: Rodríguez Vergara no hits. Vetted 28 Oct 2026 on the scans: the telegrams of GARV..2.2.4 read with the day-of-week key of GARV..1.1.4 (f. 44r, 31 Jan 1931), e.g. f. 149 (cañonero to Caucayá, 126 men) and f. 153 (a regiment of 600 infantry and mountain artillery sent to Loreto). A second key (Presidency, June 1932) is in GARV..2.2.1 ff. 6v-10. One numeric telegram (f. 151, No. 143) is in another system and was not tested. Key lookup, not an open target.
- no. 1562 Lope de Soria (imperial ambassador in Genoa) → Charles de Lannoy, viceroy of Naples, partly in cipher 7 Mar 1527 — Estense catalogue (Lodovico Media Library / Estense Digital Library): Lettera parzialmente cifrata. No decipherment mentioned in the record. Not on DECODE, not in the repo (known.py (your repo + DECODE + Cryptoole list) on the names: no hits). Soria's own keys of 1523 (keys A and B) and his 1527 cipher to Charles V are rebuilt in the repo (targets/soria1523, soria1527), so a key may transfer.
- no. 2012 Count Münster's papers on the war between Russia and France: reports from Göteborg, Kolberg, St Petersburg, Dresden and Lisbon, part ciphered and part never deciphered 1810-13 — Finding aid: "teils chiffriert (ein Teil nicht dechiffriert)". Viewed: ff. 141-143 are unbroken digits with nothing written over them; aufn_0198 has decipherment between the lines.
- no. 2118 Philip IV → marquis of Velada, ambassador to England: 35 letters, many in numerical cipher, "23 of the letters are not deciphered" 29 Jun 1636-29 Mar 1641 — Morgan: "Many letters are in a numerical cipher. 23 of the letters are not deciphered". The other 12 deciphered letters should give a crib or key. Catalogue 372 (The Hague, Koninklijk Huisarchief) holds two short runs from a Philip IV to Velada letter of 17 Dec 1640, which needs the same cifra.
- no. 342 David Ungnad, imperial ambassador at Constantinople, to Maximilian II: a despatch wholly in cipher 12 Mar 1576 — The 12 Mar 1576 despatch (Türkei I 32-3 ff. 199-203), not deciphered and not seen: not digitised or on DECODE; needs an HHStA reproduction order, then a test of R392.
- no. 566 Count Willem Lodewijk of Nassau-Dillenburg (stadtholder of Friesland) ↔ his brothers Johann VII and Georg, correspondence mostly in cipher 1605-1620 — Finding aid as quoted; Nassau keys in the same Bestand, digitised. Not on DECODE. Digitised: images in the Archivportal-D/DDB viewer. 27 Oct 2026, Brice Dudout (email): the key is in key book C 667 (image 55); the 1620 letters are limited by the microfilm. Work in progress.
- no. 1625 Hesse: Chiffernschlüssel and a ciphered letter of the Kassel regents to Duke Ulrich of Württemberg 1534 — Regests list a key in one file and a ciphered letter in the other; the key may open it.
- no. 1771 Hopken and Carlson's despatches from Constantinople to the King, 1739-41: heavy numeric cipher, much of it apparently unsolved 1739-1741 — Catalogue: plain "Brev till Kungl. Maj:t". About a third of the sampled images are whole pages of numbers; only a few carry a visible decipherment.
- no. 1533 Harford Jones (Baghdad) code: Jones → Dundas 1798 with clear copy, and two informant letters from Erzeroum 1801-02 17 Dec 1798; 20 Nov and 19 Dec [1801], received Jan-Feb 1802 — Worked as targets/jones1802/ (in progress, read in part): 1798 key rebuilt from the 49/51 pair; the same code book reads the 1802 letters, 91% of groups at grade H, the rest graded proposals. Catalogued on QDL as 'Letter in Cypher' with no decipherment
- no. 1549 Dieci di Balìa → Machiavelli at the French court, letter entirely in cipher 14 Jul 1510 — BNCF catalogue: entirely in cipher, no decipherment mentioned; bibliography only Tommasini (no edition cited). The content probably survives in clear in the ASF Dieci outgoing registers (Legazioni e commissarie / Missive) and may be printed in Bertelli 1964; not checked.
- no. 1567 Francesco I d'Este (letters countersigned by Fulvio Testi) → Ottavio Bolognesi, Paolo Francesco Forni and Francesco Ottonelli, partly in cipher (two deciphered) 7 Feb 1630 - 25 Oct 1647 — Estense catalogue (Lodovico Media Library / Estense Digital Library): Lettera cifrata, in risposta a quella ducale del 22 luglio 1634. | Lettera cifrata. | Lettera cifrata. Destinatario incerto. | Lettera parzialmente cifrata (ma decifrata alla c. 15). Destinatario incerto. | Lettera parzialmente cifrata (ma decifrata alla c. 22). | Lettera parzialmente cifrata, controfirmata da Girolamo Graziani. | Lettera parzialmente cifrata. No decipherment mentioned in the record. Not on DECODE, not in the repo (known.py (your repo + DECODE + Cryptoole list) on the names: no hits). Five 1630 Testi/Bolognesi letters partly in cipher without decipherment noted; two (14 Mar 1630 c. 22, 22 Feb 1630 c. 15) deciphered. Testi's letters are edited (M. L. Doglio, Lettere, Laterza 1967, 3 vols): check whether these are printed and read.
- no. 1773 Simon Dorffler's despatches from Poland to the King, 1686-89: numeric cipher between the lines, marginal summaries only 1686-1689 — Catalogue: plain "Brev till Kungl. Maj:t". Image 470 viewed: numbers between clear German lines, each run underlined; the margin has one-line summaries, so only fragments are glossed.
- no. 1923 Andrew Fletcher, Lord Milton: account book, inverted folios in cypher with two keys to cyphers 1738-1739 — Catalogue: 'On the inverted folios are an account in cypher and two keys to cyphers'.

- no. 1453 Magonista letters intercepted at St. Louis: consul's transcriptions, some in cipher "no se encuentran descifradas", with a sibling file of deciphered letters and key lists 1907 — AGN Guía: vol. 802 exp. 2 and vol. 803 exp. 2: "algunas cartas vienen en clave y no se encuentran descifradas"; vol. 803 exp. 4: "algunas cartas cifradas"; vol. 803 exp. 3: some letters deciphered and lists of the keys they used. Narváez 2015 shows the 1907-08 magonista systems were simple substitutions on names (from AHDSREM 11-4-198 and L-E-954), not these AGN files.
- no. 1637 Hessen-Darmstadt: 'Geheimalphabet und Personenverschlüsselung' in letters of Landgravine Dorothea Charlotte and de Voss 1635 (letters from the 1630s) — Finding aid: 'Geheimalphabet und Personenverschlüsselung'. Digitised.
- no. 1056 Gonzalo Fernandez de Cordoba, the Great Captain -> secretary Miguel Perez de Almazan, letter entirely in cipher 21 Sep 1500 — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-11 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1058 Gonzalo Fernandez de Cordoba, the Great Captain -> the Catholic Monarchs, military news (French troops concentrating at Canosa) with some paragraphs in cipher 21 Mar 1503 — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-11 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1078 Gonzalo Fernandez de Cordoba, the Great Captain -> the Catholic Monarchs, letter on the war in Calabria, mostly in cipher; undated c. 1500 (undated) — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-8 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1079 sender not stated -> the Catholic Monarchs c. 1503 (undated) — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-8 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1391 Vaudreuil → the minister, cipher letter, Montréal, weeks before the capitulation 13 Aug 1760 — Title only ("Lettre chiffrée ... au ministre"), no content summary, unlike the deciphered despatches around it: the ANOM/LAC describers apparently could not read it. Not on DECODE, not in repo. Key lead: "Chiffre ou code de Montcalm et de Vaudreuil" 1757-58, ANOM COL C11E 10 ff.285-290v (nouvelle-france.org id 15213, 10 images); Vaudreuil acknowledged receiving the ministry cipher 22 Sept 1756 (C11A 101 f.105). Possibly related to the "Vaudreuil to Berryer announcing in figures the loss of the colony" row in research/calames_biblissima (different series; check whether it is a copy).

Wilkinson's Spanish cipher is said to have been a numerical dictionary code; web search found no key for these items and no print. Shepherd's 1904 AHR article and the Spanish Papeles de Cuba not compared.
- no. 343 Johann Joachim von Sinzendorff, Constantinople, to Rudolf II: despatch wholly in cipher 3–7 Sept 1578 — The 3-7 Sept 1578 despatch (Türkei I 37-2 ff. 1-8), not deciphered and not seen: not digitised or on DECODE; needs an HHStA reproduction order.
- no. 1310 Sforza chancery letters wholly in cipher, ASMi Carteggio Sforzesco cart. 1597 (59 records) 15th century (DECODE gives the placeholder 1450) — DECODE status N/A, all records unclassified, no metadata. Already noted in CATALOGUE.md as set-aside catalogue 292 ('may be key samples or exercises, check the images'): the images checked here show real enciphered letters, so this returns the pool with new evidence. DECODE also holds 115 key records from the same box (cart. 1597, record_type 2), e.g. no. 14 Simonetta-Vincentius/Stavoli.
- no. 1311 Sforza chancery letters in cipher, ASMi Carteggio Sforzesco cart. 1598 and 1591 (110 records) 15th century (DECODE placeholder 1450) — DECODE status N/A, unclassified.

- no. 1332 Ferdinand I → Giovanni Battista Castaldo (Transylvania), four Latin letters with long cipher passages 13, 15, 18 and 22 Oct 1552 — OPAC: "Lettera a Giovanni Battista Castaldo con testo cifrato" (four records). Viewed cc. 10r and 35r: cipher in the letters themselves; partial marginal decipherment on c. 10r only, so the key can be started from the glossed passages and carried to the unglossed pages. Not on DECODE; no repo hit (known.py: Castaldo, G 275).
- no. 1554 Seven different cipher letters filed with Cardinal Ercole Gonzaga's autographs, no key, no dates undated (Ercole Gonzaga 1505-1563; probably 1540s-1550s) — Estense catalogue (Lodovico / Estense Digital Library): seven cipher letters, no key, no dates, no decipherment noted. Not on DECODE, not in the repo (known.py (your repo + DECODE + Cryptoole list) 'Campori', 'Ercole Gonzaga': no hits). Siblings in the same fonds carry cipher with decipherment (Ercole → Ferrante Gonzaga, June-July 1544, sfasc. III cc. 88-110: enclosures 'in cifra e decifrati'), which may share the key.
- no. 1555 Ippolito Capilupi → Ferrante Gonzaga, letter with cipher inserts and no decipherment undated (1539-1557) — Estense catalogue: cipher inserts WITHOUT decipherment. Not on DECODE or in the repo. A sibling, Capilupi to Ercole Gonzaga, Rome 18 June 1544, enclosed 'in cifra e decifrata' in Ercole's letter to Ferrante of 28 June 1544 (Lettera G, sfasc. III cc. 88-92), gives a likely key source.
- no. 1769 King Charles XII's letters to Colonel Thomas Funck at the Porte (Bender period): numeric cipher passages 1711-1713 — Catalogue: plain "Brev fran Kungl. Maj:t", no mention of cipher.

- no. 553 Dietrich von Schönberg and Grand Master Albrecht: letters 'in Chiffern' with no Auflösung noted 1516-1523 — The listed OBA pieces. The contemporary Auflösung filed with 22755 and others may give the key.
- no. 562 Landgrave Philip of Hesse ↔ King John Zápolya, Hieronymus Łaski, Nickel von Minckwitz and Lodovico Gritti, with cipher key and translations 1527-1532 — Finding aid as quoted; how many letters lack a translation is not stated. The repo read Łaski's 1531 Bavarian cipher (targets/kaa4591b), a likely sibling system. Not digitised.
- no. 564 Wilhelm von Grumbach and Margrave Johann of Küstrin: partly ciphered letters (1551, 1556) and the Dresden file of Grumbach letters and ciphers (1563-66) 1552-1566 — Finding aid as quoted; the Dresden file holds the ciphers with the letters. Not on DECODE. Digitised: images in the Archivportal-D/DDB viewer. 27 Oct 2026, Brice Dudout (email): not online; he has written to the archive for a quote.

- no. 627 Charles V: instruction to the Cardinal of Trent (Madruzzo), entirely in cipher 10 Jun 1546 — Paz, Catálogo V (1912) no. 1521: "Instruccion de lo que vos el Reverendisimo Cardenal de Trento haveys de dezir negociar y tractar con [Vela] de nuestra parte. Ratisbona 10 Junio 1546. Firma de Carlos V. Toda en cifra." Footnote: "Lo subrayado en cifra. La palabra [Vela] no consta en la clave": the cataloguer had a key and read at least the title; no descifrado listed. known.py "Cardenal de Trento", "Madruzzo": no hits.
- no. 781 Cornwallis ↔ Clinton cipher letters left undeciphered (Friedman's photostats and worksheets) 1780-1781 — Guide (Sheldon 2014, p. 284): 'copies of undeciphered correspondence between Cornwallis and Henry Clinton ... WFF's work sheets'. The same folder holds the British ciphers Lovell deciphered. Not on DECODE (known.py: no hit beyond the read Cornwallis-Balfour target balfour1781).
- no. 794 Barras → Rochambeau, Newport, letter partly in code, "not decoded" 3 Aug 1781 — Archives at Yale: "Partly in code, (not decoded)". Sibling Barras letters of 11 Aug 1781 (folder 218, interlinear decipher; DECODE R2856 "Decrypted") and 17 Aug (folder 221, digitised, interlinear decode) are in the same series, and Series II Box 5 folders 294-298 hold codes and tables (numbered code with a simple substitution; Talmadge; Robert Morris). Not digitised.
- no. 1037 Fontenay to Nau (Mary Queen of Scots' secretary): cipher letter with an 'illegible interpretation' 1 Jul 1585 — Calendar says the contemporary interpretation is illegible. Repo targets/sp53 notes the 'Mary-Fontenay cipher' (SP 53/22) as a neighbouring key; Fontenay's letter of Aug 1585 (no. 25) is deciphered in the same volume.
- no. 1323 'Il Solito' / 'Pellegrino' letters to Cardinal de la Cueva's agent: leaks from Venetian ambassadors' despatches via the secretary of the Venetian Inquisitors 20 Jan - 19 May 1629 — BL: 'Partly in cipher'; keys prefixed in the volume.

- no. 2015 Duke Heinrich the Younger with his councillors on Brunswick and Goslar, the Rammelsberg and the libel against Saxony and Hesse: large parts in cipher 1540-42 — Finding aid as quoted. Not digitised. A printed study (https://www.sav.sk/journals/uploads/0307161001500opt.pdf, search snippet only) reproduces a single-letter cipher of Heinrich c. 1540 from 1 Alt 8 Nr. 490, so this may be a key lookup; not promoted.
- no. 401 King Carlos I → Queen Amélia, code telegram of 5 Mar 1903 (yacht Amélia, Oran), no decode 4 Mar 1903 — 27 Oct 2026 (WAINUT, PR #105; targets/carlos1903/): the unit holds three code telegrams of 1903. Two (12 May, and one undated) were read from decodes of the time filed with them (m0058 and the card m0060) and are written up. This one (m0056, 47 items) has no decode and is not read; the code is not rebuilt. The clear letters run to 1905.
- no. 408 King Manuel II → Queen Amélia, letters and telegrams, some in cipher 2-8 Aug 1910 — DigitArq: some documents in cipher; no decipherment noted. Digitised; not on DECODE. 27 Oct 2026 (WAINUT, PR #105; targets/manuel1910/): the three code telegrams are of 2 and 8 Aug 1910, Bussaco → Pena (Sintra) (m0015+m0017, m0019, m0021+m0022, 93 items); transcribed and dated, not read. No decode in M13, no codebook found; the code is not Sabugosa's.
- no. 784 Continental Congress diplomatic letters: cipher passages still undeciphered in 1956 (Wharton, Revolutionary Diplomatic Correspondence vols. 4-5) c. 1779-1782 — Guide p. 26: 'These extracts refer to passages in cipher which had not yet been deciphered in 1956.' The repo has one sibling (targets/dana1783, Wharton vol. 6). Founders Online editions may have decoded some since.
- no. 863 Whitworth's Russia despatches, copies 'partly in undecoded cipher' 1708-1709 — Deciphered versions exist in the same volume for the duplicates, giving paired plaintext and ciphertext. Not digitised.
- no. 880 Secretariat of State (Cardinal Barberini) -> Nuncio Ceva, Paris: Francia 346 items 12-73 (mixed dossier: clear letters, cipher leaves with interlinear decipherment, undeciphered cipher leaves incl. Madrid 1634 enclosures) 1632-1634 — DECODE R5625-R5686 'N/A' (no decipherment filed; private_ciphertext flag set). Same dossier as R74-R84 whose key Lasry reconstructed; none of R5625-R5686 appears in the repo. Bagno 1652 NOTES say Lasry's Francia 346 key does not fit Francia 104, which does not bear on these siblings. Unchecked as of 28 Oct 2026: the 'online' tag is inferred from the DECODE record (images not opened, DECODE needs a login); some N/A records may be key sheets or clear text.
- no. 906 Royalist intercepts: De Vaux -> Du Chastel (12/22 May), Slingsby to La Haye (18 Jul) and Marces copies, partly cipher not deciphered May-Jul 1659 — CSP Domestic notes say "a key to the cypher has been formed from decyphers interlined"; remaining figures not read.
- no. 944 Letter partly in the cipher of John Marsh, then the same wholly in cipher not deciphered (4 pp.) c. Apr 1570 (calendar no. 812) — Crosby: 'Written partly in the cipher of John Marsh. Pp. 3. 812. The above in cipher, not deciphered. Pp. 4.' The plain portion of the preceding entry is a crib for the 4-page cipher copy.
- no. 1019 Hyde: instructions for his secretary Edgeman (mission to Scotland), plus two further copies by Edgeman mostly in the King's cipher and in Nicholas's cipher 13 Jul 1651 — Calendar entry 540. The plaintext is summarised in the calendar entry itself; the two cipher copies are not said to be deciphered. Same volume prints many letters deciphered by Nicholas, Hyde or Edgeman (royalist key rebuildable). Not looked up on DECODE (Bodleian, not on DECODE list).
- no. 1040 Sir Arthur Chichester (Lord Deputy) to the Earl of Salisbury: short numerical cipher passage printed in the calendar, 'to be expounded by the cipher your Lordship sent unto me' 7 Apr 1608 (as printed; context is the Earl's flight, so the year may be 1607, to confirm) — Calendar prints the numbers unread and says only that Salisbury's cipher is to be used. Salisbury-Chichester cipher letters elsewhere in the same volumes are deciphered or printed in clear.
- no. 1169 Père Hacki (Jesuit agent in Poland) → Queen Christina of Sweden, c. 18 ciphered letters on the Polish election 31 Oct 1668 - 19 Apr 1669 — Catalogue: 'Lettre chiffrée sur les affaires de Pologne'. Eight neighbouring sheets are 'Mise en clair d'une dépêche chiffrée' (nos. 237-239, 242, 244, 245, 249, 253), i.e. clear versions of Hacki's own cipher letters, plus the glossed no. 228: the key can be rebuilt from them. No decipherment of the ciphered sheets themselves is noted. Not on DECODE (known.py, 28 Oct 2026). Checked 28 Oct 2026: 28 Oct 2026 verify: Calames confirms no. 234 (16 Nov 1668) as 'Lettre chiffrée sur les affaires de Pologne'; no images online, no published decipherment found. Neighbouring clear 'mise en clair' sheets remain the route to a key. Printed-edition check, 28 Oct 2026: Partly in print. Arckenholtz, Mémoires concernant Christine reine de Suède, t. III (Amsterdam 1759), section on the Polish election (pp. ~340-390): extracts and paraphrases of Père Prieur Hacki's despatches and Christina's instruction to him, from 'Negoziati di Polonia'; the dated Hacki letters (31 Oct 1668-19 Apr 1669) are not printed in full Arckenholtz notes that he holds Christina's ciphers (four kinds, from Rome) and that some of her ciphered letters are undeciphered in print. His source is a Roman/Neapolitan collection, not shown to be Montpellier H 258. Extracts give context and some cribs (nuncio, Neubourg, Moscovite) but not the letters.
- no. 1336 Cesare Speciano ↔ Carlo Borromeo, Rome-Milan letters with cipher passages 4 Jul 1574; 2 Mar 1575 — OPAC notes as quoted; no decipherment noted. Not viewed. F 47 inf. n. 131 (Speciano, "lettera cifrata" with the translation on f. 270r) is in the same correspondence and can serve as a key source. Not on DECODE; no repo hit (known.py: Speciano, Spetiano).
- no. 1338 Melchiorre Biglia (nuncio at the imperial court) → Rome, two letters in numeric cipher copied into his letter-register Oct 1565 — OPAC: "Alle cc. 6v-7v: 2 lettere cifrate". Viewed c. 7r: ciphertext copied into the register. The original despatches are in the Vatican (Germania) and Biglia's nunciature is edited in Nuntiaturberichte aus Deutschland II/5-6, which may print a deciphered text (crib). Not on DECODE; no repo hit (known.py: Biglia, Trotti 22).
- no. 1460 Porfirio Díaz (and his secretary Rafael Chousal) → Gen. Bernardo Reyes: about 45 cipher telegrams the catalogue marks "sin traducción" Nov 1885 - Jul 1909 — CEHM records read "Sin traducción" / "[Legajo sin traducción]" with type "Telegrama cifrado"; hundreds of sibling Díaz-Reyes cipher telegrams in the same fondo carry summaries of their content, so a key can be rebuilt from translated pairs. Ángel & Morales-Luna 2008 print a Díaz substitution table (Díaz-Bravo) from the Porfirio Díaz archive (Universidad Iberoamericana).
- no. 1463 Francisco León de la Barra papers: coded telegrams and letters (interim presidency and Huerta-era diplomacy) Jun 1911 - Nov 1913 — CEHM records "En clave" with no translation for these five (X-1.4.310.1 has a summary, so it was read); translated drafts and a key sheet in the same fondo.
- no. 1536 Brig. Gen. C. C. Augur (Dept of Texas) to Lt Gen Sheridan and Maj. G. B. Russell: three 'Cypher' telegrams during the Texas gubernatorial crisis (Davis/Coke), Jan 1874 12 and 17 Jan 1874 (three telegrams) — Newberry's volunteer transcription (Newberry Transcribe) types the three telegrams as scrambled word strings, e.g. 'Dresden I persons to it fussy unauthorized forward ... Cypher state Grant ...'; no plaintext is given. The 18 Feb 1869 letter in Ayer MS 3039 (Grierson papers, box 03 f.153) describes the army cypher method then used in Texas: write the message in 4 to 9 columns, a key sets the reading order, key words are substituted. Not checked on DECODE beyond known.py (no hit for Augur cipher). Scan viewed 29 Oct 2026 (collections.newberry.org, Image w/ Text): letter-book page 31 with telegrams 8529 (to Sheridan, 12 Jan 1874), 30 and 45 (to Russell, 12 and 17 Jan 1874) in clerk's hand as scrambled English words with code words (Dresden, Cheyenne, Neces, Houston, Waco); no decipherment on the page.

No decipherment mentioned in the description.
- no. 1988 Philip III → Rodrigo Niño Laso, conde de Añover: reales cédulas in cipher (four with no decipherment bound in) 1610-1611 (four undated-in-print leaves; others of the series 27 Jan - 23 Jul 1610/11) — Hispana/Memoria de Madrid records 'Real cédula cifrada'. Page 2 of the scan viewed: whole page of 2-4 digit groups mixed with a few letters (la, de, fal, ba), no interlinear or banderilla decipherment. Eight sibling cédulas of the same series have the decipherment bound in on a slip (banderilla), which gives cribs.
- no. 1991 Francis Drake, Genoa → Lord Grenville: copy letters in cipher, one partly deciphered by Macartney 5 and 26 Sept 1795, and one letter of 1795 — Catalogue: 'Copy letter in cipher'; /56 'partly deciphered by Macartney'; /159 'Letter in cipher'.

- no. 336 Siena, "Lettere in cifra" of the Concistoro: the pieces still unsolved (nos. 4, 7, 14, 15, 19, 21; no. 1 of 1421 unphotographed) 1421 (no. 1); nos. 7, 19, 21 1440s-1450s — Nos. 7 (R4796, 363 signs), 19 (R4807, 118) and 21 (R4809, 107): no key; none of the filed keys fits, and neither George Lasry nor this project has deciphered them. No. 1 (Meister's 1421 letter), 2 and 26-28 are not photographed; they need the Archivio di Stato di Siena. No. 4 (R4793, 144 signs): key rebuilt from an alphabet fragment and the glosses, 114 signs given a value, no sentences. No. 14 (R4802): key recovered from the ciphertext alone, L01-L26 decoded, not read. No. 15 (R4803): partly deciphered by George Lasry by crib guessing (no key filed), decoded, not read.
- no. 434 St Petersburg to Ogrodzki, ciphered leaves of 1769-70 1769-1770 — The 1769-70 leaves. The 1765 volume carries its own explained key and is a lookup once imaged.
- no. 639 Joel Roberts Poinsett → James Monroe, Santiago de Chile, despatch with at least nine cipher passages printed as '(undeciphered cipher)' 20 Feb 1813 — Manning 1925 vol. 2, doc. 442, pp. 896-897, prints the despatch with '(undeciphered cipher)' at each coded passage; the State Department returned Poinsett's other letters to him in 1818, so his own copies (some 'Part in cipher', May-July 1811 from Buenos Aires, per the HSP list filmed at M37 roll 2 frames 20-22) are at HSP, possibly with plaintext drafts. Not in the repo (known.py: Poinsett no hits). Worked 28 Oct 2026 (targets/poinsett1813, write-up poinsett1813): 437 groups transcribed; the same-code letter of 14 June 1814 (no. 651) carries a clerk's decipherment, 95 values, 161 of 437 groups of 1813 get a value, no sentence reads. Other State Department rolls searched (M37 1-2, M70, M77, M84): no further letter in the code.
- no. 649 Delacroix (French Foreign Minister) → Létombe (French consul general, Philadelphia), despatch No. 5 entirely in a French numeric code, copy sent by Rufus King 25 Messidor an V (13 July 1797); enclosed in King No. 53, London, 12 Nov 1797 — Transcribed in full by Michael Brackx (issue #122, 27 Oct 2026; transcription in the issue). King's No. 53: 'I have no means of decyphering it'; no decipherment on frames 0236-0252. Turner, Correspondence of the French Ministers 1791-1797 (AHA 1903) does not print No. 5, but prints Létombe's reply No. 42 (22 Brumaire an VI, p. 1077, from the ministry's decipherment, CP États-Unis 48 f. 355): he will follow what the 25 Messidor despatch prescribed for keeping his political correspondence, 'dont je dicte moi-même les chiffres'. So part of No. 5 is probably about the keeping and ciphering of his political letters. Statistics: repeats 705 806 711/400 405 ×7, 474 670 1068 ×3; adjacent frequent pairs 972/973 and 81/82 hint at a one-part code, but a one-part word anneal did not converge; flat profile (top ten 14%). Not on DECODE. 2 Nov 2026: worked in targets/delacroix1797/, still unread. Near-repeated passages interchange neighbouring numbers (e.g. 417 269/416 268, 123 151/124 152), which suggests homophones in small numeric blocks, and a calibrated one-part test found no alphabetical order (real text overlaps scrambled numbers; the method recovers about half of a synthetic one-part letter). Annealers failed calibration on synthetic letters of the same size; seven French keys in the repo are within chance.
- no. 657 Bernstorff (German Embassy Washington), second code text on the State Department cable of 11 Jan 1917 (groups 147-576), unread 11 Jan 1917 — 27 Oct 2026 (WAINUT, PR #115; targets/bernstorff1917/): groups 0-146 are Bernstorff's telegram No. 205 of 10 Jan 1917, printed by Bernstorff (1920, pp. 325-326) and in Official German Documents II p. 1017; aligning them gave 82 groups of a two-part four-figure code with prefix figures (not 13040; probably 0075 [?]). Written up. The memorandum on frames 0769-0775 is not the plaintext. This entry is now the second text, 430 groups in the same code, unread. 2 Nov 2026 (section 10 of the notes): the code is Code 7500 of Friedman and Mendelsohn 1938 by route and structure (this cable not named there); their nine sibling telegrams were not found on the digitised reels; catalogue 635 keeps no groups; the text is not in Bernstorff 1920 or Official German Documents. A crib needs PA AA, TNA HW 7/ADM 137, or State Department files on site.
- no. 722 Papers intercepted from a French cabinet courier near Irún, 1809 (various correspondence) 1 Apr - 20 Jul 1809 — PARES hit for "sin descifrar" (27 Oct 2026), title: "Documentación interceptada a un correo de gabinete francés cerca de Irún en 1809. Correspondencia variada"; images flagged in the hit list. PARES full-text search seems to match the words, not the phrase (a 1494 lawsuit and Falla letters also hit), so the term match is a pointer, not proof of an undeciphered cipher. not on DECODE or in the repo (known.py: no hits for the signatura or names). || Brackx, issue #176 (28 Oct 2026): Not a cipher: N.49 'Carta cifrada' is a Hebrew-cursive (probably Yiddish) letter, and the 'key' N.50 (images 24-29) is a Jewish calendar for 5569 printed at Metz by Abraham Speyer; the Marqués de Lazán's covering letter (N.40, Tortosa, 20 July 1809) took the calendar for the key. Not checked here (PARES 429).
- no. 818 Thomas Fossey's notebook of veterinary recipes, sections in a vowel-to-digit cipher 1710-1716 — Catalogue: "Some sections are completed in a cryptographic code". Fully digitised. Seen 28 Oct 2026: vowels replaced by digits, trivially readable. Not on DECODE.
- no. 835 Astrological and medical compilation with occasional words written in cipher end of the 15th century (after 1485) — Catalogue (Dutschke, Guide to Medieval and Renaissance MSS, repeated in HDL record): 'occasional words written in cipher (e.g. ff. 50, 102v, 111, 143, 163)'. No reading given. Probably the common vowel-substitution of English medical manuscripts (cf. HU 1051, where the cataloguer read 'Pr4pt2r 1m4r2m m5l32r3s'). Fully digitised on HDL. Not in the repo. First pass 28 Oct 2026 (targets/hm64/): ff. 163r and 111r viewed on HDL; the red hatched boxes on 163r/163v are crosses in Latin charms, not cipher; two candidate cipher words located (163r heading 'T R y 6 z l e t h', 111r heading 'S C G e G N T'), neither read; ff. 50r and 143r show none; f. 102v and the versos unviewed. Vowel-to-number substitution not confirmed.
- no. 860 Atterbury plot: cipher papers obtained by Shortiss; decipherers say 'cannot be decyphered without vast trouble'; 'Undecyphered paper' Nov 1723 — Catalogue: decipherers could not read it without more text. Neighbouring SP 35 ciphers exist. Not on DECODE.
- no. 881 Paris despatches of 1591 (sender to be identified; Nuncio Sega not confirmed) to Cardinal Caetani and the Pope, ciphered, Francia 32 1591 — DECODE R5612-R5621 'N/A'. CATALOGUE.md (line 61) mentions this as 'catalogue 297: Meister and morosini1588 keys to try', but catalogue.json has no live entry 297 and no R5612-R5621 anywhere else in the repo. Only R5617/R5621 are named in bagno1652 NOTES as unrelated neighbours. Unchecked as of 28 Oct 2026: the 'online' tag is inferred from the DECODE record (images not opened, DECODE needs a login); some N/A records may be key sheets or clear text.
- no. 905 Charles I to Ormond, original "in cypher, not decyphered", carried by Col. John Barry 15 Dec 1644 / 18 Jan - 6 Mar 1645 — Calendar note only; the Ormond-Hyde ciphers are partly known. Sibling no. 2424 is "decyphered on following paper".
- no. 919 Spanish court despatch to Wolsey, 2 Apr 1518, mostly in cipher, undeciphered 2 Apr 1518 — Brewer: 'Hol., pp. 9, mostly cipher; encloses Sir J. Stile's letter on the English ambassadors' arrival, undeciphered'. A long, mostly ciphered letter with no sibling decipherment in the volume.
- no. 920 Spanish court despatch to Wolsey, 30 Jun 1518, mostly in cipher, undeciphered 30 Jun 1518 — Brewer: 'Hol., pp. 6, mostly cipher; Aragonese Cortes oath to Charles, undeciphered'. A long, mostly ciphered letter with no sibling decipherment in the volume.

Throckmorton, to Secretary Cecil; one of them wholly in cypher and not explained'. Throckmorton's cipher family is in the repo (targets/throck1569).
- no. 965 Charles I (Newcastle) to Ormond: wishes a safe way of intelligence; duplicate original in cypher, not decyphered Aug/Sep 1646 — Ogle & Bliss: 'In cypher. A duplicate original; not decyphered.' Neighbouring Ormond ciphers are decyphered in the same volume (e.g. 'Decyphered on following paper'), so the royalist Charles-Ormond key can be rebuilt from siblings.
- no. 966 Charles I to Ormond, cypher in duplicate, not decyphered (answers Ormond and Digby despatch of 2-3 Dec) early 1648 (reply to Ormond/Digby of 2-3 Dec) — Ogle & Bliss: 'Cypher. In duplicate, not decyphered.' Neighbouring Ormond ciphers are decyphered in the same volume (e.g. 'Decyphered on following paper'), so the royalist Charles-Ormond key can be rebuilt from siblings.
- no. 967 Sir Edward Hyde (Jersey) to Secretary Nicholas: nearly all in cypher, not deciphered (secret commission under the Great Seal, Glamorgan?) 29 Apr 1648 — Ogle & Bliss: 'Nearly all in cypher, not deciphered. Some expressions point to a secret commission under the Great Seal; possibly that of Glamorgan.' Neighbouring Ormond ciphers are decyphered in the same volume (e.g. 'Decyphered on following paper'), so the royalist Charles-Ormond key can be rebuilt from siblings.
- no. 1039 The French ambassador in England (Chateauneuf) to Courcelles in Scotland, two letters in cipher with no decipher listed (entries 72 and 73) 2-3 Sep 1586 (from the marginal dates; to confirm) — Calendar lists both as 'In cipher' and none of the neighbouring entries is a decipher of them. Intercepted in the wake of the Babington arrests (Giffard/Phelippes). Possibly deciphered in the manuscripts without a calendar note.

- no. 1194 Manassès de Feuquières → baron de Rorté on German affairs, six letters largely ciphered 14 Mar - 25 Apr 1634 — Catalogue: original 'en partie chiffré' (or 'en grande partie chiffré'); no decipherment noted. Not on DECODE (known.py). Checked 28 Oct 2026: Verified 28 Oct 2026 on Calames: Feuquières to Rorté, 14 Mar-8 Apr 1634 (ff. 110-117 listed), originals 'en grande partie chiffrés'; no decipherment note. Different from repo targets feuquieres/feuquieres1678. No online images found. Printed-edition check, 28 Oct 2026: Not found in the printed edition checked. Lettres et négociations du marquis de Feuquières (Paris 1753), t. I-III searched (archive.org lettresetngoci01-03feuq): no Feuquières letter to Rorté of 14 Mar-25 Apr 1634 is printed; only the 'Mémoire de Mr de Feuquières pour servir d'instruction à M. le Baron de Rorté' (t. II pp. 78-79, for Brandenburg) and mentions of Rorté in other letters Avenel's Lettres de Richelieu not searched. Feuquières 1753 prints the surrounding Brandenburg/Saxony negotiation in clear, useful as context. Long-s OCR is noisy, so a miss is possible.
- no. 1231 Ferenc Wesselényi (palatine) → unknown, two letters mostly in cipher, Sztrecsény and Murány 1663 10 Oct and 20 Nov 1663 — Hungarian regests (Hungaricana): original Hungarian letters of the palatine, mostly cipher, no decipherment. Not on DECODE. Checked 28 Oct 2026: Regest 146641 (Verschwörerakten IV) is a 'Titkosírás kulcsa' (cipher key) item, so a key exists in the same files; a web search found the 20 Nov 1663 Wesselényi letter regest ('feloldás nélkül') but no printed decipherment. Not verified that Hungarian editors never printed it.
- no. 1236 Philip III → Ambrogio Spinola, seven letters in cipher, 1618 (Bohemian revolt, Ostend fleet, Nassau, Dutch West India company) 18 Jan - 23 Dec 1618 — Manuscriptorium/BNP record only (Pouze popisný záznam, no images in Manuscriptorium).

Key lead: the Simonetta-Vincentius/Stavoli key is ASMi cart. 1597 no. 14 on DECODE, and R7900 (f. 89, Angelo Simonetta at Venice, 30 Sept 1446, 'Cum cifra Vincentii') has its contemporary clear text on R7901 (f. 90), per targets/it1583 notes. Mazzatinti does not mark f. 151 'in cifre', so check how much of R7912 is cipher.

- no. 1772 Simon Dorffler's despatches from Poland to the King: numeric cipher passages in German letters 1680-1683 — Catalogue: plain "Brev till Kungl. Maj:t". Images 277 and 304 show dense lines of numbers; no decipherment seen on them.
- no. 1854 Henri IV (or his camp) to Sillery, from the camp of Chamoux: original almost entirely in cipher 3 Sep 1600 — Calames: original almost entirely ciphered; sender and printing not given.
- no. 389 Copy-book of letters to the marquês de Sande in England from the conde de Miranda, Cardinal Orsini and Gaspar Dias de Mesquita, 1660-61, with cipher documents 1660-1661 — DigitArq: copy-book containing ciphered documents; no decipherment noted. Miranda's cipher for the same correspondence is bound in MMCG 3L (key leaves 3L/000003, 000020). Not digitised; not on DECODE. 26 Oct 2026 (targets/miranda1660/): attempted; neither the copy-book (letters 1-113) nor the volume holding its two 3L keys (ff. 3, 30) is digitised; both must be ordered from ANTT. Nothing transcribed.
- no. 501 Vrančić, Zay and Busbecq → Ferdinand I from Amasya, 'chiffriert, keine Dechiffrierung vorhanden!' 28 May 1555 — AIS 'Inhalt: chiffriert, keine Dechiffrierung vorhanden!'; some 60 sibling despatches of 1553-57 in Türkei I 10-13 are 'chiffriert und interlinear dechiffriert', so the embassy key is recoverable.
- no. 534 Caulaincourt (Congress of Châtillon) → Napoleon: letters in cipher 'sans le déchiffrement' / 'le déchiffrement manque', filed beside deciphered sisters 20 Feb - 15 Mar 1814 — AN inventory (FranceArchives): 'Lettre en grande partie chiffrée (et sans le déchiffrement) de Caulaincourt à Napoléon, 25 février 1814'; 'Lettre chiffrée ... (le déchiffrement manque), 6 mars 1814'. Same plaquettes hold four cipher/decipherment pairs of the same weeks — a ready crib. 27 Oct 2026, Brice Dudout (email): Fain and Houssaye print the plain texts.
- no. 538 Marquis de Villeneuve, French ambassador at Constantinople → Maurepas: letter 'non déchiffrée' and a partly ciphered letter 'non transcrite' 18 Feb - 2 Apr 1737 — AN inventory: '[Lettre chiffrée] - Lettre non déchiffrée'; '[Lettre partiellement chiffrée, non transcrite]'. The repo read Villeneuve's 1737 letters to Jean Otter (villeneuve1737, BnF Français 22225) — same year and writer. Lasry read Villeneuve's 1737 letters to Otter (targets/villeneuve1737); try that key first.
- no. 574 Intercepta of Margrave Ludwig Wilhelm of Baden, Jan-Jun 1704: letters of Chamillart and Marsin marked 'chiffriert' (the lead's 1703 and Tallard are not in the part of the finding aid read) Jan-Jun 1704 — Finding aid as quoted; listed but not rowed in research/central_archives. French army ciphers of the War of the Spanish Succession are a known family. Not digitised.
- no. 1495 Rio Branco → Assis Brasil, cipher telegrams (Zeballos crisis) 9 Jan 1905 - 7 Oct 1908 — NUPERGS: 'Texto cifrado' with no content. Prior art: in the 1908 'telegrama nº 9' affair Rio Branco published a cipher telegram of 17 June 1908 to Santiago with its decipherment to refute Zeballos; if the Itamaraty code of 1908 was published then, it is a key lead (not verified).
- no. 1584 Chomętowski's embassy to the Porte: ciphered letters and reports with their solutions and code 1713-1714 — Catalogue: 'Szyfrowany list', 'Kopia szyfrowanego listu', 'Urywek' (nr 902, 970, 1019, 1035, 1040, 1043, 1052, 1053, 1056, 1058, 1060, 1061) beside 'Rozwiązanie szyfru' sheets and 'Kod szyfrowy' (nr 1062). Several letters have no solution listed.
- no. 2009 Guerre contre la Russie: Bavarian file on the 1812 campaign with cipher tables and ciphers noted as not resolved 1811-13 — Finding aid: "Chiffriertabellen (a) alphabetisch, b) numerisch) (teilweise in französischer Sprache, teilweise Chiffren (nicht aufgelöst))". The tables in the same volume probably read them.
- no. 410 Conde de Sabugosa → Queen Amélia, code telegram of 13 May 1903 (Lisbon → Paris), no decode 13 May 1903 — 27 Oct 2026 (WAINUT, PR #105; targets/sabugosa1910/): the unit holds telegrams of 13 May 1903, 24 Apr 1904 and 21 and 24 May 1910. The last three were read from decodes of the time in the same unit (m0008, m0005+m0004, m0009) and are written up; pairing gave 52 values of a one-part code. This one (m0014, 43 groups) has no decode; 6 groups have a value.
- no. 454 Charles XI's full power for the Swedish commissioners (Nijmegen), partly in cipher 6 May 1677 — Catalogue: "Latin, delvis i chiffer". No decipherment noted. Not on DECODE, not in the repo. The clear 1676 power in the same folder is a near-certain crib for the formula. Listed as a lead (not scanned) by the 24 Oct Riksarkivet sweep.
- no. 473 Thomas Harrison and William Jephson → Henry Cromwell, letters partly in numeric cipher, partly decoded 10 Jun 1656 - 17 Mar 1657 — EMLO (Henry Cromwell catalogue): 'The letter is written in part in a substitutional numeric cipher. It has been transcribed in code ... and attempts at decoding have been made in the footnotes' — i.e. partial decoding only. Not in the repo (known.py: Lansdowne 821 no hit).
- no. 554 Elector Joachim I and Grand Master Albrecht: ciphered letters with no Auflösung noted 1519-1520 — 22850 (ciphered copy) and 23943. 22553 is printed deciphered in Joachim II no. 79.
- no. 555 Heydeck, Isenburg and Schönburg to Grand Master Albrecht: reports with no Auflösung noted Jul-Nov 1520 — 23484, 24365, 24382 and the Anlage of 23888.
- no. 568 Landgrave Georg II of Hesse-Darmstadt: encrypted letters with Gallas, Hatzfeldt, Mercy, Holzapfel, Geleen and his councillors (Thirty Years' War) 1634-1647 — Finding aid as quoted. Key 'Alphabete und Chiffren einer Geheimschrift' (Georg II-Friedrich, 1651-58) and 'Blätter mit Auflösung von Chiffren' (Ludwig VI) are digitised. Saxon copy of a Hesse-Darmstadt alphabet: HStA Dresden Loc. 08285/18 (1639-40). Digitised: images in the Archivportal-D/DDB viewer. 27 Oct 2026, Brice Dudout (email): key B confirmed; two fully enciphered pages from Ferdinand III's war council (31 Jan 1637) have no decipherment. Work in progress.
- no. 590 Frederick II ↔ Duke August Wilhelm of Brunswick-Bevern and Field Marshal Schwerin, orders and reports 'meist in Geheimschrift (Ziffernchiffre)'; Frederick → Lehwald 1756; Frederick → Queen Ulrike of Sweden 1756-1757 — Finding aid as quoted. Most of these orders are printed in the Politische Correspondenz Friedrichs des Großen from the minutes, so the reading may already exist; the letters to Ulrike less certainly. Not digitised.
- no. 593 'Relations en chiffre du Ministre de Prusse', Saxon cabinet file (Prussian envoy's ciphered reports) 1748 — Finding aid as quoted. If intercepted Prussian dispatches (Klinggräffen/Voss), GStA Rep. 81 Dresden nach 1807 Nr. 782-784 hold the same ministers' cabinet orders 'mit Auflösung'. Not digitised.
- no. 625 Document in cipher with an English cover, not deciphered (Patronato Real, England papers) undated (late 15th / early 16th c.) — Paz, Catálogo V Patronato Real (1912) no. 4715: "Documento en cifra con sobre inglés. S. f. Ni descifrado. 2 hoj. fol., en mal estado de conservación." No. 4716 is Catherine, Princess of Wales, to Dr Puebla. catalogue.json already has three PTR leg. 52 Puebla-code items; this one's PARES DOC number is unknown, so it may coincide with one of them: check before merging. 28 Oct 2026: Brice Dudout's PARES sweep proposes PTR,LEG,54,13 (PARES 2208053, "Documento en cifra") as this document, very probably; the mapping is his and is not confirmed here (images not seen).
- no. 796 Earl of Jersey → Earl of Manchester, Whitehall, part in cipher never printed 15 Apr 1700 — Not on DECODE (its Manchester records are R2854-R2872), not digitised. Same correspondence and period as R2859/R2860, deciphered here with the THE=454 key (targets/yard1699).
- no. 833 Francis Drake (British minister at Munich) → Charles Stuart, partly in cipher, three pages partly obscured 20 Sep 1803 — Finding aid: 'partly in cipher with three pages partly obscured.' Unlike its siblings (31 Oct 1803, Folder 36; 14 Feb 1804, Folder 37: 'partly in cipher with Stuart's autograph reading of the cipher') no reading is noted. Not on DECODE; not in the repo.
- no. 865 Prince Rupert to unknown, in code (not deciphered) 9 Aug 1645 — Catalogue says not deciphered. Rupert 1645 letters were read with Lasry's SP 106 keys (targets/rupert1645). Not on DECODE.
- no. 866 Sir Henry Wallop to Walsingham, cipher partly deciphered and partly obliterated 8 Feb 1580 — Catalogue: 'Cipher, partly deciphered and partly obliterated'. The Pelham cipher of Nov 1579 (Carew MSS, Lambeth Palace Library) is a key lead. Not on DECODE.
- no. 934 Dr Nicholas Wotton to the Lord Protector: first and larger part in cipher, undeciphered 1550 (calendar no. 97) — Turnbull: 'Five pages. The first and larger part in cipher, undeciphered' (about the Interim). Wotton's cipher is the family of his 1554 letters in this repo's catalogue (DECODE R8499 key R354).
- no. 940 Dr Wotton to the Council: first portion in cipher, undeciphered (liberation of Sir Gawen Carew) Jan 1554 (calendar no. 316) — Turnbull: 'Seven pages and a half. The first portion in cipher, undeciphered'; the next item is dated 28 Jan. Year inferred from the calendar sequence: verify. Wotton key R354 exists.
- no. 949 Thomas Fowler to Walsingham, Edinburgh: partly in cipher not deciphered early Mar 1586 (no. 598) — Calendar: '1 p. Holograph. Addressed. Indorsed. Partly in cipher not deciphered.' Walsingham's Scottish agents used a family key (repo cat. 81-82).
- no. 1031 Secretary Bennet (Lord Arlington) to the Lord Lieutenant: Irish bill; passage in cypher follows ('The King is informed that ...') 12 Dec 1668 — Calendar omits the cypher passage; no decipher mentioned. Ormond-Arlington cipher letters of 1680 are in the Ormonde calendar, so the key family is known.
- no. 1034 Montereul to Cardinal Mazarin: levies for Spain, effect of the army coup in England; eight lines undeciphered June 1647 — Fotheringham printed the letter with eight lines left undeciphered. Montereul's letters to Brienne in the same series are near-copies and sometimes carry the plain text (editor p. 498).
- no. 1139 Duke of Richmond to Prince Rupert, mainly in code 15 Aug 1644 — Catalogue: 'mainly in code'. Same network as the Legge letters. Checked 28 Oct 2026: Not opened; search found nothing on a decipherment.
- no. 1160 Albrecht Kraus → Duke Johann Wilhelm of Saxe-Weimar: letters and documents in a "Geheimsprache", with its key (Gotha Chart. A 40) 27 May 1567 (letter); key undated — Kalliope: "Schlüssel einer Geheimsprache, die für die vier Briefe und Dokumente in Chart. A 40, Bl. 187r-203v verwendet wird" (DE-611-HS-3435271); the 27 May 1567 letter (DE-611-HS-3435230) is "Betr. seine vertraulichen Verhandlungen mit Johann Rosa und die Verwendung einer Geheimsprache". No digitised images linked. Not on DECODE, not in repo. Possibly a code vocabulary (Deckwörter) rather than a letter cipher: unknown. Checked 28 Oct 2026: Re-checked: no decipherment or edition found; key (Bl. 186a) is catalogued in the same volume as the four letters, so a key-plus-text pair is likely. No images online per Kalliope.
- no. 1166 Giovanni Rizzardo (Venetian secretary, London) to the Inquisitori di Stato, ciphered despatches with cipher keys, loose in Melzi's Marescalchi rosso 1615 — LBC description: 'documentazione cifrata del sec. XVII con chiavi di cifrario', attributed on the folder to Rizzardo's despatches from London to the Inquisitori di Stato, 1615; probably set aside for an 'espurgo' of the Venetian Inquisitors' archive and gathered by Melzi. Not on DECODE; no repo hit (known.py: Rizzardo, Marescalchi, Inquisitori di Stato). CSP Venetian calendars the ASVe copies of Rizzardo's Sept 1615 despatches as deciphered, so the Milan sheets may duplicate a known text. Checked 28 Oct 2026: Not re-verified this round: no online images (archive description only). Verdict kept as in the entry. (could not be verified: see prior_art)
- no. 1170 Archbishop of Corinth (nuncio) → Queen Christina of Sweden, two ciphered despatches on Polish affairs 21 Nov 1668 and 1 May 1669 — Catalogue: 'Dépêche chiffrée'. The same volume holds the nuncio's 'mise en clair' of other despatches (nos. 23, 54, 57), so a key may be reconstructible. No decipherment of these two noted. Checked 28 Oct 2026: 28 Oct 2026 verify: Calames confirms no. 132 (Warsaw, 21 Nov 1668, f. 168) 'Dépêche chiffrée sur affaires de Pologne'; no images online; no published decipherment found. Printed-edition check, 28 Oct 2026: Partly in print. Arckenholtz t. III, same section, reports the nuncio's views by paraphrase; the two nuncio despatches of 21 Nov 1668 and 1 May 1669 are not identified as printed Weak: paraphrase only. Åkerman and published Vatican correspondence not searched.
- no. 1213 Armand du Lau du Chambon's papers: ciphered correspondence of Louis II de Bourbon, prince de Condé (Fronde) 1651-1652 — Departmental inventory: 'correspondance chiffrée de Louis de Bourbon, prince de Condé'. SHD GR 1KT 211 (Brianson papers) holds five ciphered Condé letters of 1651 with transcription and method: a possible key, so class B. Not on DECODE. Checked 28 Oct 2026: Checked 28 Oct 2026: AD Dordogne 2 E 1841-18 inventory says 'correspondance chiffrée de Condé' 1651-52, no images on page. SHD GR 1KT 211 (Papiers Brianson) lists five ciphered Condé letters of 1651 'accompagnées de la transcription et de la méthode de décryptage' (photocopies, cf. 1 Kmi 62): a likely key/crib, not online. Printed-edition check, 28 Oct 2026: Not found in the printed edition checked. No match: the entry is an inventory line ('correspondance chiffrée') with no letter-level data; Lenet's Mémoires and Aumale's Histoire des princes de Condé t. VI not grepped (nothing specific to search for) Sibling lead: Lasry, 'Armand de Bourbon's Poly-Homophonic Cipher - 1649' (HistoCrypt), Conti's Fronde cipher in BnF fr. 3584; test whether the Dordogne ciphers use the same system.
- no. 1445 Félix Díaz's felicista conspiracy: agents' letters with code-name passages the cataloguers left "claves no descifradas" Aug 1921 - Jun 1922 — CEHM catalogue: "incluye claves no descifradas" / "clave sin descifrar" on each record. Narváez (2015) broke two members of this family (Argumedo's number-pair names, DCXXI.3.244.1 / 3.250.2, and the Wellington letter DCXXI.6.588.1, a "modern method" letter cipher) and showed the catalogue phrase means "cipher not translated"; the other letters listed here are not discussed in his article.
- no. 1446 Bernardo Reyes → Porfirio Díaz, cipher letters from Monterrey left "sin traducción" (Coahuila crisis) 12 Nov 1885; 15 Apr 1886 — CEHM records: "Sin traducción" (DLI.2.292.1) and "En cifras" (DLI.4.649.1), document type "Carta cifrada". Sibling cipher letters Reyes↔Díaz/Revueltas of Nov-Dec 1885 (DLI.2.267.1, 2.400.1, 3.455.1, 3.525.1) carry summaries, so their plaintext exists in the fondo.
- no. 1448 José López Portillo y Rojas → Bernardo Reyes, cipher letter during the 1909 Reyista campaign 15 Jul 1909 — CEHM record has no content summary, only the type "Carta cifrada"; the next López Portillo cipher letter (29 Jul 1909, DLI.39.7712.1) has a summary, so a translation or key may be in the same file.
- no. 1465 Gen. Pablo González's Constitutionalist correspondence: messages wholly "en clave" (Carranza, Rábago, Fuentes Dávila, Murguía) Jan 1913 - Jun 1914 — CEHM: "La comunicación está en clave" / "El documento está en clave" with names only; the fondo also holds "clave alpha-32" (LXVIII-1.23.3148.1) and records of keys sent and received.
- no. 1478 Lindolfo Collor papers: 21 cipher telegrams on the eve of the Constitutionalist Revolution 5-9 Jul 1932 — CPDOC: 'Telegramas cifrados' / 'sobre os acontecimentos que antecederam à revolução constitucionalista'; only LC c 1932.07.09/4 has a content summary. Collor's code lists (pseudonyms, codes) are in the same fonds: LC c 1930/1932.00.00/11 (12 docs, 22 ff.).
- no. 1479 Lindolfo Collor papers: cipher telegrams from Borges de Medeiros, Vargas and Aranha, 1927-30 14 May 1927 - Sept 1930 — Most CPDOC summaries give the content (so likely deciphered on the sheet); LC c 1930.02.03 and LC c 1930.09.00 do not. Key material in LC c 1930/1932.00.00/11.

- no. 1485 Pedro Ernesto papers: coded telegrams of the 1930 revolutionary conspiracy (João Alberto, Estillac Leal, Luzardo) 18 Jun 1930 - 15 Feb 1933 — Summaries give content (so translations are probably attached). Key in the same fonds: PEB c 1930/1932.00.00/3 'Relação de cifras' (18 ff.).
- no. 1500 Benito Varela, Paraguayan foreign minister → Manuel Moreira de Castro, consul general in Rio: letter with numeric cipher passages 13 Feb 1850 (letter in a file of 1849-1853) — ANA description, item 13: 'se refiere a otros asuntos que no pueden ser identificados por estar escritos en código cifrado' (i.e. the cataloguer could not read it). Viewed on the scan 28 Oct 2026: numeric substitution (letters or syllables) inside a clear letter about Brazil, Rio Grande and Buenos Aires. Not on DECODE, not in the repo. Vetted 28 Oct 2026: scan transcribed; no decipherment on or with it; no key known; not on DECODE, no edition or study found. Verdict open. Next: page through the other 96 images of 558-1-31 and the sibling López-era files for a key or a deciphered copy.

Digitised (btv1b10033937d). Not in Daniel's repo. Tomokiyo (cryptiana henryiii.htm) covers Luigi d'Este → Villeroi 1584-86 (fr. 16041-16042) with a printed edition: possibly the same cipher family (not verified).
- no. 1754 Chiffrierte Antwort des Grafen Appónyi auf eine Mitteilung Metternichs (vgl. Acta secreta 352) (ciphered, per AIS) 07.1831 — AIS: 'Chiffrierte Antwort des Grafen Appónyi auf eine Mitteilung Metternichs (vgl. Acta secreta 352)'. No decipherment is mentioned in the record.

Not in the repo (known.py: only the DECODE/Cryptoole dumps; Cryptoole marks it 'na'). The other ciphertext records of the same Mediceo key volumes (R7019, R7021, R7024, R7234) carry a plaintext and are marked solved by Cryptoole; this one has none.
- no. 758 Coahuila state code telegrams on the Mexican Kickapoo affair, Múzquiz ↔ Saltillo, 1906: two-digit code passages that the Mexican Embassy could not decipher 25 Jun - 27 Jul 1906 (copies sent to the State Department 8 Nov 1907) — Found in the slice L word-hit triage of RG 59 (research/nara_triage_l/agent_59.md); the reel OCR was read again here (27 Oct 2026). The Senate subcommittee on the Mexican Kickapoo land frauds (Teller) obtained copies from the Federal telegraph office at Múzquiz and asked the Department for a decipherment; the Mexican Embassy could not read the code, suggested a state governors' code, and the copies were returned to Teller. Nothing later on the roll deciphers them. Repeated numbers inside words (10 35 30 18 / 10 35 70 18) and code mixed into clear text suggest a simple two-digit letter or syllable substitution with Spanish plaintext. known.py: no hits for Kickapoo, Múzquiz, Guajardo; not in catalogue.json.

This code has not yet been deciphered'; the web-indexed finding aid says the key sits in the puzzles series. The series runs to 1959, so part falls after the 1950 limit. Not in repo, Cryptoole or DECODE list (known.py: Covert gives only Humphrey Covert 1601). Not viewed.

The plain text was published in 1930, so the content is known; the French cipher system itself was never reconstructed. Not in the repo (known.py: Keefer, Bazaine no hits).
- no. 650 Anthony Morris → James Monroe, coded despatches with no decipherment on record: No. 18 (Seville, 20 Sept 1814), No. 28 (Madrid, 12 May 1815) and the despatch on M31 roll 14 frames 0220-0221 c.

It is a candidate plaintext for the 43 groups, untested beyond a negative word-for-word one-part check. The volume holds decipherments of five letters from the abbé de Périgord to Mirabeau.
- no. 744 Gomez Suarez de Figueroa, Genoa: cipher letters to Charles V and Prince Philip 1534-1557 (20 items, several systems, no decipherments seen) 1534-1557 — PARES hits (27 Oct 2026, "carta cifrada"/"cifrada"), item titles "Carta cifrada de Gómez Suárez de Figueroa ..." or "Duplicado de carta cifrada ...". PARES full-text search matches words, not the phrase, so a term hit is a pointer; the hit-list title says the letter is in cipher, not whether a decipherment is filed with it. Not in the repo (known.py: no hits for the legajos; the Suárez de Figueroa hits are Lorenzo, Venice 1504). 28 Oct 2026: a further ciphered piece in the same legajo run, not in the list above, is catalogue 840 (EST,LEG,1380,151-154, 1549); its sender is not stated, so it may not be Figueroa.
- no. 745 Doria, Sfondrato, Requesens, Farnese, Olivares: cipher letters in the Genoa legajos 1572-1588 (30 items, no decipherments seen on six viewed) 1572-1588 — PARES hits (27 Oct 2026, "carta cifrada"/"cifrada"/"en cifra"; EST,LEG,1410,134 also "no descifrada"). PARES full-text search matches words, not the phrase, so a term hit is a pointer; the hit-list title says the letter is in cipher, not whether a decipherment is filed with it. Not in the repo (known.py: no hits for the legajos or Sfondrato; Olivares's 1592-93 cipher is cited in targets/sessa1593).
- no. 753 Unattributed cipher letters filed in the AGS Estado Genoa legajos (1551, 1577, 1585) 1551-1585 — PARES hits (27 Oct 2026, "carta cifrada"/"cifrada"): titles "Carta cifrada."

(EST,LEG,1418,47, 50, 81, 1585) and a duplicate for Juan de Idiáquez (1418,82). PARES full-text search matches words, not the phrase, so a term hit is a pointer; the hit-list title says the letter is in cipher, not whether a decipherment is filed with it. Not in the repo (known.py: no hits for the legajos).
- no. 754 Spanish ambassadors in Genoa (Sancho de Padilla, Miguel de Oviedo, Juan de Idiáquez, Pedro de Mendoza / conde de Binasco, Juan Vivas) and García de Toledo: cipher letters and duplicates to Philip II and Philip III (1565-1603) 1565-1603 — PARES hits (27 Oct 2026, "carta cifrada"/"cifrada"; EST,LEG,1401,54, 1416,11 and 1416,79 also "no descifrada"). Pairs of "Carta cifrada" and "Duplicado de carta cifrada" of the same letter are common (e.g. 1414, 1416). PARES full-text search matches words, not the phrase, so a term hit is a pointer; the hit-list title says the letter is in cipher, not whether a decipherment is filed with it. Sibling of the Binasco 1592 row already here (EST,LEG,1424,79). EST,LEG,1394,247 (PARES 3576569, García de Toledo to Philip II, 16 July 1565), found in the sweep, is targets/toledo1565/, already solved, and was taken out of this row at the merge review (27 Oct 2026); its key (two-digit homophonic, 12-43) is the first to try on the García de Toledo items here. known.py missed it because the repo writes "AGS Estado leg. 1394 no. 247", not "EST,LEG,1394,247"; re-run with "leg. 1401/1405/1408/1410/1413/1414/1416/1418/1419/1430/1432": no other hits for the remaining legajos (checked 27 Oct 2026).

Reported by Brice Dudout (28 Oct 2026): neither on DECODE nor in this repository as far as he can see. His key for the Caprile/Cistarelli cipher reads part of it (one line so far). He has asked ASMo for the original. Not checked here. Attempted 28 Oct 2026 (targets/cistarelli1520/, joined to catalogue 158: same two-digit cipher as R1137): addressee Alfonso I and place Kraków per Vestigia and the clear text (reports Cardinal Ippolito's death); line 7 transcribed, R1137 anneal key gives fragments only; about six cipher lines at the foot lost in the photocopy. Needs the original.
- no. 854 Ramón de Cardona, viceroy of Naples → Charles I: four letters partly in cipher 5 Mar 1517 - 18 Jun 1520 — BNE catalogue: 'cuatro cartas con firma autógrafa, en parte cifradas'.

- no. 968 Sir Edward Hyde (Jersey) to Lord Digby: a portion interspersed with cypher, not decyphered Sep 1646 (no. 2320) — Ogle & Bliss: 'A portion of the letter interspersed with cypher, which is not decyphered.' Neighbouring Ormond ciphers are decyphered in the same volume (e.g. 'Decyphered on following paper'), so the royalist Charles-Ormond key can be rebuilt from siblings.
- no. 969 Sir Henry Bennet (Rome) to a lord: great part in cypher, 'still undecyphered' (praises Digby's negotiations, wants recall) 1645 (entry before the Jermyn letter of 31 Aug) — Ogle & Bliss: 'A great part of this is in cypher, which is still undecyphered.' Neighbouring Ormond ciphers are decyphered in the same volume (e.g. 'Decyphered on following paper'), so the royalist Charles-Ormond key can be rebuilt from siblings.
- no. 978 Royalist agent letter, Jan 1656 (item 67, Vol. CXXIII): italicised cipher passages undecyphered (Ross/Nicholas series) Jan 1656 (item 67, Vol. CXXIII) — Green: 2.75 pp.; italics are cyphers, undecyphered; Norfolk and Suffolk rising (Hobart). Preface: the Nicholas-Jane letters are 'ordinary figure cypher' decyphered from Jane's interlineations; the Ross-Nicholas ones use another cypher with no key. The editor deciphered much of the series, so the gaps are small.
- no. 981 Royalist agent letter, Feb 1656 (item 76): italicised cipher passages undecyphered (Ross/Nicholas series) Feb 1656 (item 76) — Green: 2.75 pp.; italics in cypher, not deciphered; stars represent words with no key.

- no. 489 Emperor Ferdinand III → Field Marshal Holzapfel and General Traun, despatches 'in Chiffern ohne Klarschrift' (Thirty Years' War, last campaign) 3 Dec 1647 - 11 Jan 1648 — AIS titles say explicitly 'Original in Chiffern ohne Klarschrift' / 'chiffriert ohne Klarschrift'; the many sister despatches of the same weeks are glossed, so the imperial field cipher can be rebuilt from them. Not on DECODE. 27 Oct 2026, Brice Dudout (email): not online; he has written to the archive for a quote.
- no. 490 Emperor ↔ Elector of Saxony, two letters 'in Chiffern (ohne Klarschrift)' around the Kötzschenbroda truce 1-5 May 1645 — AIS: 'in Chiffern (ohne Klarschrift)' for both; no decipherment noted. Imperial chancery cipher of 1645 should match the glossed Kriegsakten siblings of 1643-48.

Chapuys's despatches to Charles V are calendared (CSP Spain, Bergenroth/Gayangos) and Charles V keys are on Tomokiyo's cryptiana; the Luxeuil letters are less studied. A printed text may exist (27 Oct 2026), but the manuscript is not online, so the print cannot be matched to the cipher yet.
- no. 510 Letters to the imperial ambassador in Madrid, Count Pötting, 'teilweise verschlüsselt' (Lamberg, Goess, Cardinal of Hesse, Balbases, Porcia, Empress Eleonora) 1663-1674 — AIS remarks 'teilweise verschlüsselt' with no decipherment. Leopold I's own letters to Pötting were printed with their ciphers resolved (Pribram & Landwehr, FRA II 56-57, 1903-04), so the embassy key family is known.
- no. 513 Imperial-Spanish correspondence on Flanders, 'verschlüsselt': Archduke Leopold Wilhelm, Castel Rodrigo, Lisola 1642-1667 — AIS 'teilweise verschlüsselt'; no decipherment noted. Castel Rodrigo also wrote ciphered letters in Kriegsakten 119-79 'chiffriert und Klartext' (a crib).
- no. 518 Mexican Empire correspondence of Archduke Maximilian with passages in Geheimschrift: General Almonte and Arrangoiz May - Sep 1863 — AIS: 'Schreiben mit Geheimschrift beigelegt'; 'Verwendet teilweise Geheimschrift'. No decipherment noted.
- no. 524 Mercy-Argenteau (French minister in Munich) → Maret, duke of Bassano, report with cipher passages 28 Sep 1813 — Kalliope: 'Chiffre/Geheimcode/Geheimtext'; 'Teilw. abgedruckt und übersetzt ins Engl.' — a partial printing exists, extent of cipher coverage unknown. A printed text may exist (27 Oct 2026), but the manuscript is not online, so the print cannot be matched to the cipher yet.
- no. 525 Wilhelm von Wolzogen, Württemberg chargé d'affaires in Paris: correspondence and reports, partly encrypted 1792-1793 — Kalliope/DLA: 'Korrespondenz, Berichte, z.T. verschlüsselt, über die Lage im Paris der Revolution: Hinrichtung des Königs...'.
- no. 530 Holstein-Gottorp diplomatic correspondence 'z.T.' or 'meist chiffriert': Dumont in Paris, Pechlin in Stockholm, Goertz, Bonde, Buchwaldt 1713-1744 — Archivportal-D titles: 'z.T. chiffriert', 'meist chiffriert'; the 'Konzepte' files of the same series likely hold the clear drafts (crib). The repo's goertz1717 target concerns Görtz's chancery key (Riksarkivet), a lead. 27 Oct 2026, Brice Dudout (email): Abt. 8.1 Nr. 2231 holds Bonde's letters from Russia; Dumont is Nr. 2298-2348. Nr. 2247 (cipher) and 2248 (contemporary decipherment) would be an ideal pair.
- no. 535 Saint-Marsan (French minister in Berlin) → Maret, despatch 'non déchiffrée' 24 Nov 1812 — AN inventory: 'Extrait d'une dépêche de Saint-Marsan : dépêche non déchiffrée. 24 novembre 1812'; nos. 231-235 are his other despatches of Nov 1812.
- no. 537 French consuls at St Petersburg and Moscow → secretary of state for the Navy: cipher passages left 'non déchiffrés' / 'non transcrits' (Lavie 1720, Decury de Saint-Sauveur 1747, Martin and Lesseps 1778) 1720-1778 — AN inventory: 'Lettre chiffrée ; folios 311-313 non déchiffrés'; 'fin chiffrée non transcrite'; 'Texte chiffré non transcrit'. The inventory analyses most other ciphered letters, so decipherments of siblings exist in the volumes. The 24 Oct Archives nationales sweep closed the consular letters whose content the inventory summarises; this inventory marks these folios as not deciphered.
- no. 539 Marquis de Châteauneuf, ambassador at Constantinople → Louis XIV and Pontchartrain: 'la partie chiffrée n'est pas déchiffrée' Apr 1691 - Jul 1694 — AN inventory: 'la partie chiffrée n'est pas déchiffrée' (f. 155, 239, 433) and 'le texte chiffré n'est pas déchiffré' (f. 232). The repo's CATALOGUE notes twelve Châteauneuf despatches elsewhere; same embassy cipher family.
- no. 546 Jean de La Fin, sieur de Beauvoir-La-Nocle → the duke of Bouillon, letter partly ciphered 6 Mar 1593 — AN inventory: 'l.s. en partie chiffrée'. The repo lists La Fin → La Nocle's three-digit syllabic code (BnF fr. 15578) in SOLVED_CATALOGUE.md — a sibling system.
- no. 552 Mazarin → abbé Bentivoglio, letter with a ciphered passage after the defeat at Orbetello 1646 — Catalogue (via FranceArchives): 'après une partie chiffrée, le reste est de la main de Mazarin'. Mazarin's Italian ciphers are well documented (Lettres de Mazarin, Chéruel).
- no. 563 Politisches Archiv Landgraf Philipp: ciphered pieces (Eck letters 'Briefwechsel in Chiffern' 1532, Sickingen intercept 1522, Wilhelm IV-Moritz-Reckerode Chiffernzettel 1551, intercepted 'Ir Kent mich wohl' letters 1553) 1522-1553 — Finding aid: 'Briefwechsel in Chiffern' (Feb 1532), 'Aufgefangenes Schreiben Sickingens ...

- no. 589 Karl Wilhelm Saegert, Karl von Usedom and General von Wedell, encrypted letters (Wedell-Usedom mission, Crimean War, the "Usedom affair") 1854-1859 — Finding aid as quoted; drafts in Saegert's hand may sit beside ciphered fair copies. Not digitised.
- no. 592 August III → Duke Johann Adolf II of Saxe-Weissenfels on the siege of Danzig, with encrypted reports 1733-1734 — Finding aid as quoted. Saxon cabinet keys of the period: 10026 Geheimes Kabinett Loc. 03233/01-07, 03234/01-07. Not digitised. 26 Oct 2026 (targets/august1733/): attempted; not digitised; the Archivportal-D record ("Enthält auch: Verschlüsselte Berichte") is all that is online. Order from HStA Dresden.
- no. 600 Alexander Erskein's war files: Rep. 32 Nr. 463 (Bd. 2 on the 1645 Bohemian campaign and Jankau), Wrangel's letters 1646 and number-coded messages 1645-1650 1645-1650 — Finding aid as quoted. Not digitised.

These numbers are outside catalogue row #530 (Abt. 8.1 Nr. 2231-2459 selection); fold in at merge. Abt. 7 Nr. 1450 holds deciphered counterparts of Nr. 1451. Not digitised.
- no. 783 British cipher messages in the Clinton Papers left part-solved by Elizebeth Friedman (1952 worksheets) 1775-1782 (worked by ESF 1952) — Guide p. 284: 'work sheets and notes ... in connection with some uncompleted work done by ESF in 1952 on British revolutionary cryptographic systems found in the Clements Library.' Which messages stayed unread is not stated.
- no. 795 Copies of 66 "secret letters" of Charles I from the Isle of Wight, names in numerical cipher, with George Hopkins's petition 1648 (copied c. 1720) — Catalogue: "copies of 66 secret letters written by Charles I in 1648, with names in numerical cipher". Copy of c. 1720. Not on DECODE, not digitised. Originals: 61 letters sold in the UK (Friends of the National Libraries grant), others in BL Egerton 1533 and 1788.
- no. 1327 Marquis de Torcy (and Louis XIV) → Abbé de Pomponne, French ambassador at Venice, original despatches many in cipher 15 Apr 1706 - 17 Feb 1710 — BL: 'Original dispatches, many of which are in cypher'; no decipherings noted (the recipient's decipherments may be interlinear). Pomponne's own letters to Gualterio (Add MS 20338-20339) are 'with decipherings'.
- no. 1339 Nicodemo Tranchedini → Francesco Sforza, Rome despatches with cipher (Ambrosiana pergamene) 9 Jan 1452 - 2 Jan 1453 — Ambrosiana pergamene catalogue (OPAC): as quoted, no decipherment noted except for the sibling 9138-9 ("cifra spiegata", 18 Jan 1452) and 9631 ("ex cifra Nicodemi", a decipherment). No images online. Tranchedini's key is reconstructed in print (Domnina 2018, HistoCrypt) and Lasry read his 28 Jun 1452 letter (repo target tranchedini1452). Not on DECODE.
- no. 1340 Ottone del Carretto → Francesco Sforza, Rome despatches with cipher words left unexplained (Ambrosiana pergamene) 15 Jun 1457 - 28 Oct 1464 — Ambrosiana pergamene catalogue (OPAC): the four items above carry cipher without a noted decipherment; the deciphered siblings of 1457-58 give the key. No images online. Not on DECODE; no repo hit (known.py: Carreto, Z 219).
- no. 1342 Francesco Sforza → Alberico Maletta, cipher polizza enclosed in letters (pope, Nicodemo, King of Aragon) 18 Oct 1455 — OPAC pergamene catalogue: "dal Duca di Milano, in cifra"; no decipherment noted. No images online. Maletta keys are among the Sforza keys edited by Cerioni 1970. Not on DECODE.
- no. 1350 Three letters wholly in cipher to Gasparo Spinelli, Venetian resident at Naples, during the Osuna crisis 20-23 Oct 1618 — Tiepolo's 1965 inventory (transcribed 2020) lists them as wholly in cipher; no decipherment noted, unlike the Costantinopoli items of the same inventory where 'decifrazione' is stated. Not on DECODE, no repo hit (known.py: Spinelli = only the Florentine Beinecke family). Letters received abroad in Venetian cipher were read by the resident with his own key, so the clear text may survive in the Senate's Deliberazioni (Secreta, Corti/Napoli) or the Capi's registers; the originals themselves are probably not interlined.
- no. 1489 1923 Libertador revolution: coded telegrams between Alipio Teixeira, Carlos Noedo, 'Malakoff' and 'Arc' 15 Apr - 15 May 1923 — NUPERGS summaries: 'Codificado' / 'Codificado em números'. Record 2845 carries a partial translation, record 2499 a clear version; record 6208 (Tibúrcio de Azevedo → Assis Brasil, 5 Apr 1923) sets up 'um código e nomes falsos'. Not on DECODE, not in the repo.

- no. 762 Theodore Roosevelt → John Hay, coded telegram (no decoding noted) 27 May 1903 — TR Center catalogue gives no plaintext and no decoding; probably the State Department or a commercial telegraphic code of 1903, so a codebook should read it. Hay's received copy (Hay Papers, LoC/Brown) may carry the decode. Not in the repo (known.py). TR Center image server refused a scripted download (S3 AccessDenied), not viewed.
- no. 797 James Vernon → Earl of Manchester, Whitehall, paragraph in cipher (unprinted) on M. Lilienroot's project 23 Dec 1700 — Not on DECODE, not digitised. Vernon's other cipher letters to Manchester (Nov-Dec 1700) were deciphered on fly-leaves; this one has no decipher noted.
- no. 858 Frederick V (Winter King) → Johann Joachim von Rusdorf: French letter with enciphered names 18 Oct 1630 — Heidelberg description: French letter with the names enciphered. Probably a name code in an otherwise clear letter, possibly short. Rusdorf's ciphers for Oxenstierna are in the repo (rusdorff1625, rusdorff1628), but this is a different correspondence.
- no. 917 Burgos despatch to Wolsey, 27 Oct 1527, two passages in cipher undeciphered 27 Oct 1527 — Brewer: 'Burgos, 27 Oct. 1527. Signed. Pp.3. Two passages in cipher, undeciphered. Add. Endd.'

The Hyde/Marces royalist ciphers of 1659-60 are largely deciphered in the same volumes; these are the remaining gaps.
- no. 973 Enclosure: a note in undeciphered cipher with the Lockhart/Mazarin conference letters Aug 1659 — Routledge: Enclosure: a note in undeciphered cipher (220v). The Hyde/Marces royalist ciphers of 1659-60 are largely deciphered in the same volumes; these are the remaining gaps.

- no. 1337 Cesare Speciano ↔ Carlo Borromeo, six letters with cipher names and words 28 Jun - 21 Nov 1578 — OPAC notes as quoted; no decipherment noted. Not viewed. Mostly names, so a short cipher; the 1574-75 Speciano letters and F 47 inf. 131 are the key sources.
- no. 1352 Senate ducali in cipher to Giovanni Battista Lionello, Venetian resident with the Swiss 28 Jul 1620 - 25 Sep 1621 — Inventory note 201: group of ducali in cipher, mostly in two or three copies. No decipherment noted. Not on DECODE, no repo hit (known.py: Lionello). The Senate's clear drafts are normally in Senato, Deliberazioni, Secreta (Corti/Svizzeri), so the plaintext very probably survives in Venice: a crib-and-key exercise rather than an unread text.
- no. 1447 Bernardo Reyes → Ignacio Revueltas, letter half in cipher on the Garza Galán-Cervantes reconciliation 1 Apr 1886 — CEHM record gives a two-line summary and notes half the text is in cipher; Revueltas → Reyes, 24 Mar 1886 (DLI.4.630.1) asks him not to drop letters in his cipher messages. Translated siblings in the fondo.
- no. 1449 Meza Salinas → Bernardo Reyes, cipher letter left "sin traducción" 12 Oct 1901 — CEHM: "Sin traducción", document type "Carta cifrada". Other 1901 cipher letters to Reyes (I. J. Mendoza, DLI.33.6599.1, on Camilo Arriaga sheltering General Treviño) are summarised.

Sentence cut in the extract; read it before any promotion. Date assumed from the relations with France mentioned.
- no. 277 Nevers to Villeroy, Saint-Quentin 16 Aug 1595 — All 17 runs not deciphered: no key among the surviving Nevers keys, the letter as sent to Villeroy not located, and the nomenclator is beyond ciphertext-only attack at this length.
- no. 280 Mniszech to Jakub Dunin, Crown regent 18 Mar 1714 — R7524 (Mniszech, 18 Mar 1714), all 232 figures not deciphered: no key or plaintext found and the solver fails its matched control at this length, so the negative is inconclusive.

No decipherment noted; Paz's preface says embassy letters normally reached the Council as secretaries' descifrados, so decipherments may be in the same legajos. known.py: 6446, Viana, Eguiluz no hits.

Adams's letter (Founders Online) says no one in Boston would undertake them and James Lovell 'despairs of being able to make a key'. Pickering to Hamilton 18 Jun 1799: Rozier showed his cipher and Pickering checked some coded passages against Rozier's plain copies. So the Rozier letters were checked in part with the writer's own key; the other letters in the packet and a full decipherment are not recorded. Not on DECODE; not in the repo. 27 Oct 2026 (WAINUT, PR #110; targets/astrea1799/, in progress): the editors name only the two Rozier letters as in code (no. 1, 27 Oct 1798; no. 2, 22 Nov 1798 with a postscript of 23 Nov and an extract of Rozier to Hédouville of 20 Nov).

German diplomatic traffic sent over the US channel in 1916-17 was in codes 13040/0075 and was largely read by Room 40, so a decrypt may exist in TNA (HW 7, ADM 223); not checked. 2 Nov 2026 (targets/bernstorff1917/, section 10): the file copy, 841.857/244, keeps no groups; the cipher was delivered to the Ambassador on 7 Dec 1916. The telegram concerns the Arabia case. No ciphertext is known, so this entry is no crib for catalogue 657.

- no. 770 William Eustis (Secretary of War) → Joel Barlow, letter in code on Henry Wilson's secret arms export from Ostend 25 Sept 1812 — Finding aid: "In code [directs Joel Barlow, an American agent abroad, to assist Henry Wilson. Wilson will secretly export arms to the United States from Ostend in Belgium]". The bracketed summary may come from a docket or a clear passage; no decipherment noted. Barlow left Paris for Vilna in Oct 1812 and died 26 Dec 1812, so the letter may never have been read. Not in the repo; not on DECODE.
- no. 771 William H. Seward → a correspondent in Copenhagen, copy of a coded letter undated [1861-1869?] — Finding aid: "an undated copy of a coded letter Seward sent to a correspondent in Copenhagen, Denmark". No decipherment noted. Not in the repo (known.py Seward hits concern other items).
- no. 808 William Blathwayt → George Stepney, three letters from Loo, Dieren and Dyrham (cipher matched) 2 Sep 1701 - Sep 1702 — Found by the cipher-family queries in Quicksearch (the matching note sits on archives.yale.edu, which returned 403, so the cipher is not confirmed). Not digitised, not on DECODE, not in repo.
- no. 1518 José Manuel Balmaceda: autograph note written in cipher during the civil war 1891 — BN Chile catalogue; no transcription noted. The library also holds "[Códigos y claves antibalmacedistas] 1891" (3 ff., sys. 001156140), "[Códigos y claves de grupo congresista] 1891" (sys. 001156145) and a Legation list of the keys sent to Paris, 15 Jun 1891 (sys. 001083798); the government (Balmacedist) key is not catalogued. Not digitised online (no link in the record; BND search finds no scan). Not on DECODE, not in the repo (checked 28 Oct 2026).
- no. 411 Paiva Couceiro monarchist papers: letters in or partly in cipher (Taveira, Joaquim Pais), 1921, with a draft giving the cipher 1921 — 4 letters grouped. DigitArq: letter in cipher; no decipherment noted. The same bundle has Couceiro's draft with 'a cifra correspondente' (n.º 135) and letters partly in cipher (n.º 130-132). Not digitised; not on DECODE.
- no. 467 Else Iversdatter Vandal → her husband Morten Madsen Lime: a letter in cipher 1626 — Description: "Brev til Morten Madsen Lime fra Else Iversdatter Vandal 1626 (cifferskrift)". Not on DECODE, not in the repo.
- no. 506 'Einige chiffrierte Schreiben' filed with the Staatskanzlei cipher keys 16th-18th c. — Language, dates and senders unknown; the leaf must be seen to say what it is.
- no. 516 Custrianus from Constantinople, letter partly ciphered (Grafenegg family archive) 1625 — AIS 'teilweise chiffriert'. The Graz GAMS edition of Kurz von Senftenau letters prints a 1624 Constantinople letter with its ciphertext (kuse.l.hbg.16240126a1), a likely sibling; the repo read Kurz 1639 (kurtz1639).
- no. 519 Ciphered letters of the correspondent Louitgarde Pauli-Bizonky from London (Foreign Ministry information bureau) 1868 — AIS 'Chiffrierte Briefe'; no decipherment noted.
- no. 527 Theodor Körner (Carlsbad) → his father Christian Gottfried Körner, 'verschlüsselter Brief aus den Freiheitskriegen' 4 Jul 1813 — Kalliope: 'Verschlüsselter Brief'. Körner's letters are edited (Briefwechsel, ed. Wolff); whether the cipher is resolved there is unchecked. A printed text may exist (27 Oct 2026), but the manuscript is not online, so the print cannot be matched to the cipher yet.
- no. 531 Landgrave Ernst Ludwig of Hesse-Darmstadt, diaries partly ciphered 1698; 1701-1702 — Archivportal-D: 'Tagebuch, teilweise chiffriert'; no decipherment noted.
- no. 532 Letters to Father Eusebius Mantz at Reichenau, partly ciphered, with contemporary attempts at decipherment 1654 — Archivportal-D: 'Briefe an Pater Eusebius Mantz in der Reichenau (z.T. chiffriert) mit Entzifferungsversuchen' — attempts, not a decipherment.
- no. 540 French consul at Algiers → minister: 'document non décrypté pour la partie chiffrée' (f. 119-132) 30 Dec 1767 — AN inventory: 'Document non décrypté pour la partie chiffrée, notamment les f° 119 à 132'. Dozens of Algiers 'lettres chiffrées' of 1750-73 in the same series are summarised (deciphered). The 24 Oct Archives nationales sweep closed the consular letters whose content the inventory summarises; this inventory marks these folios as not deciphered.
- no. 550 Letter from Rome to the abbé Bossuet, partly in cipher, unsigned 22 Dec 1699 — Inventory: 'lettre de Rome à l'occasion des bonnes fêtes, en partie chiffrée, non signée 22 décembre 1699'. The repo's bossuet target covers BnF NAF 28227(9), the abbé's Rome correspondence of 1697-98 — same circle. The 24 Oct Archives nationales sweep noted it is probably printed decoded in Urbain-Levesque, Correspondance de Bossuet t. 12; check that first. Ciphertext not online (27 Oct 2026). The keys are in print: Urbain-Levesque, Correspondance de Bossuet t. XII has an appendix 'Clef de la correspondance sur le Quiétisme' with Bossuet's, Phelipeaux's and La Broue's keys, so a scan from AD77 should be enough to read it.
- no. 576 Baden-Durlach envoy at the Reichstag, reports partly ciphered (Seven Years' War) year not given in the finding aid (lead said 1757-1758; record lists 'Januar - Juli') — Finding aid as quoted; listed but not rowed in central_archives. Baden keys of 1759-61 (Edelsheim) in GLA 48 Nr. 67, 75. Not digitised.

- no. 612 Ewald Spöker → Josef Riklin, letters with encrypted information for the exile Josef Panholzer 1940-1945 — Finding aid as quoted; may be veiled language, not a cipher. Not digitised.
- no. 634 US minister at Vienna → Secretary of State, cable in the 1867 State Department code with the code letters run together, 'never deciphered' c. 1867-1873 (before Haswell's letter of 8 Jul 1873) — John Haswell to Hamilton Fish, 8 Jul 1873 (Fish Papers reel 95, LC), quoted by Weber, Masked Dispatches pp. 106, 131: cables from Turkey (decoded by J. C. B. Davis after long labour), Paris and Vienna arrived as strings of connected code letters; 'the latter one was never deciphered'. The 1867 code (letters and groups of unequal length, telegraphers merged them) is known (Weber 1979 prints it). 27 Oct 2026 (targets/vienna1873/): attempted; closed unread. Weber, Masked Dispatches pp. 106, 131 (Haswell to Fish, 8 Jul 1873) gives no date, sender or archive item for the telegram; the full 1867 codebook was not found online. Needs NARA RG 59 telegrams / M46 and the Fish Papers reel 95.
- no. 813 Joseph von Chlingensperg auf Berg, encrypted diary, 1825 volume (cipher broken for other years, no decoded 1825 text on record) 1825 — Finding aid: volume encrypted, cipher 'cracked by multiple sources', decoded text only for 1805-1811 material; nothing for 1825 held or published as far as searched.
- no. 834 Joseph Hooker, Army of the Potomac: ciphered telegrams on crossing the lower Potomac 20 Jan-5 Mar 1862 — Finding aid: 'Contains ciphered telegrams and a hand-drawn map of the lower Potomac.' Whether they are the coded originals or operator decodes is not stated. US Military Telegraph route cipher of early 1862; the key family (Stager cipher, Eckert books) is in the Eckert papers (catalogue 648). Not in the repo.
- no. 1026 George Gilpin (Elizabeth's agent) to Lord Robert Dudley: cipher passage undeciphered (Prince of Spain's illness, Lady Regent) 6 Sep 1561 — HMC footnote 'Cipher undeciphered' (a few words). Gilpin's cipher letters to Cecil in CSP Foreign are deciphered by Cecil's secretaries, so the key is partly known.
- no. 1326 John Dodington, English Resident at Venice: letter-books with correspondence with the Doge, partly in cipher 1670-1672 — BL: letter-books containing 'cipher'; whether the cipher passages are glossed is not stated. TNA SP 99/48/233 is 'Dodington's cypher' (a key, TNA Discovery).
- no. 1328 Comte de Froulay, French ambassador at Venice: drafts of despatches with enclosures in cypher 1734-1736, 1739-1743 — BL: 'DRAFTS of letters ... with enclosures in cypher'. The clear drafts may be the plaintext of the ciphered enclosures.
- no. 1381 Soerjotjondro (Batavia) → telegraphic address 'Epidnation', Singapore: code telegrams, not decoded Jun-Dec 1948 — Finding aid: 'De teksten zijn niet gedecodeerd en volstrekt onbegrijpelijk' (not decoded, wholly unintelligible). Original kept in Jakarta; not scanned (no ANRI image service for this fonds; the NA description says it is held in Jakarta). Not on DECODE; known.py no hits.
- no. 1386 Documents captured by the KNIL at Bandjermasin with intelligence information partly in code Jan 1947 — Description: 'met intelligence-informatie (deels in code)'. Code sheets captured in the same region in 1947 (inv. 4693 Sampit, inv. 4678) may be the key. Not on DECODE.
- no. 1459 Secretaría de Gobernación political-police cipher telegrams (DGIPS), elections, Cristero-era arrests of priests, sedition 1924 - 1949 — AGN Guía: each record lists "Telegrama cifrado" among the contents; one (caja 0223) has "su traducción", so translations exist for some; most records do not say whether the cipher is translated.
- no. 1509 Jorge Huneeus → Domingo Santa María (then minister in the field at Antofagasta), telegram in cipher 1 Jul 1879 — Archivo Nacional de Chile catalogue (Aleph ARNES) note: 'Texto en clave', no transcription noted (the catalogue does note one on most sibling telegrams). Not digitised online (no 856 link in the MARC record). The same fonds holds 142 cipher telegrams of 1879-1886 with transcriptions attached and two key sheets: A3039 "Código para escribir en clave" (ca. 1880) and B4931 "Claves telegráficas a utilizar con Lynch, Altamirano, Novoa y todas las legaciones chilenas en el extranjero" (ca. 1883, 10 p.).

- no. 1519 'Marco' → Claudio Matte (Berlin): 22 telegrams partly in cipher on watching the property and persons of the Balmaceda administration 23 Aug - 1 Sep 1891 — BN Chile catalogue: information in cipher; no decipherment noted. Claudio Matte was the Congressist agent in Germany; the Congressist code sheets (sys. 001156145, 001156140) are in the same library. Not digitised online (no link in the record; BND search finds no scan). Not on DECODE, not in the repo (checked 28 Oct 2026).
- no. 1524 Ministerio de Gobierno, orden público: municipal and departmental despatches to the Minister, most in cipher, a few with their translation 1911-1912 — AGN description: most of the oficios/telegrams are in cipher; the few that carry their translation concern the hunt for "revolucionarios" and alerts of coups.

- no. 1894 Joseph von Chlingensperg auf Berg, partially encrypted diary (1830) 1830 — Archives at Yale title "Partially encrypted diary". The same series holds a 20th-century "Translation of 1811 diary, with related papers" (Box 2), which may give the system. Not digitised, not on DECODE, not in repo.
- no. 814 P. R. Shield diary (London, Switzerland, Milan, Tynemouth) with notes in an unidentified cypher 28 Jun 1838 - 31 Dec 1839 — Catalogue note. Not on DECODE, not in repo; Quicksearch lists the format as Images too, so it may be digitised.

Ruiz) and President Obregón, photostats 'not translated' June 1921 — Card: photostats of telegrams 'in code and clear', 'not translated'. MI-8 broke several Mexican government codes in 1917-19 (files 10531, 10640, 9700; Clave Garduño / Clave Relaciones, 8530-14), so the 1921 code may belong to a known family.

- no. 899 Valladolid despatches to Wolsey, part and one sentence in cipher, undeciphered 30 Oct and 13 Nov 1524 — The calendar note means the manuscript carries no contemporary decipherment; the editor may have read some of it, so the printed abstract can already contain the sense.

- no. 1032 'John Poingdexter' (name as OCR) to [unnamed], Dublin: Ireland in a desperate condition; a passage in cipher follows 2 Jan 1646 (year to confirm) — Calendar omits the cipher passage; sender's name garbled in OCR and the recipient is blank in print, so check the printed page before the merge.
- no. 1053 Bishop of Hirache -> secretary Miguel Perez de Almazan, letter on the payment of courier costs, part in cipher 1 Mar 1500 — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-11 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1102 Ferdinand, King of the Romans -> Lope de Soria, 9 Apr 1535: cipher part untranslated (a separate translation sheet exists, 2 leaves) 9 Apr 1535 — The 1931 catalogue states the cipher part is not translated/deciphered. This is the incoming correspondence of Lope de Soria; his outgoing letters to Charles V are RAH Salazar A-28 (DECODE R9488-R9498) and are already worked in this repo (targets/soria1527, 1523 key A/B).
- no. 1113 Juan Yniguez (Rouen) -> Alexander Farnese: letters entirely in cipher (inventory does not say whether deciphered) 1588 — Inventory says the decipherment is missing; Farnese fascio 397 holds key tables for many cipher correspondences and fascio 1624 the key for Alexander's letters to his mother 1578-79 (per the inventory introduction). Not on DECODE (known.py: no hits).
- no. 1143 William Swyfte despatch 'largely in cipher' 24 Feb 1657 — Catalogue: largely in cipher.

- no. 1247 Vice-chancellor A. I. Ostermann → I. P. Kalushkin, Russian resident in Persia, rescript in cipher 28 Apr 1737 (N.S.) — Commons description gives the shelfmark, calls it a cipher rescript; no decipherment noted.
- no. 1263 Mar to Lord Grange, letters with cipher passages (Mar and Kellie) Jul 1710 - Dec 1711 — Not checked beyond the NRS hit list; may only mention a key.
- no. 1351 A 'replica' wholly in cipher among letters from other Venetian ambassadors to Francesco Corner, ambassador in England 1706-1707 (letters 23 Jun 1706 - 12 Aug 1707) — Inventory: original letters to Corner from Dolfin (Vienna) and Tiepolo (France), 'qualche altra lettera isolata ... altra «replica» tutta in cifra'. No decipherment noted. Not on DECODE, no repo hit (known.py: Corner, Garzoni). Ambassador-to-ambassador letters used a shared Venetian cipher; Corner held the key, so the clear text was probably never filed.
- no. 1384 Penilik Djawa Timoer: coded telegram on sabotage of the Malang transmitter, with a Poesat Badan Pengawas Oemoem report 31 Jan 1947 — Description: 'met gecodeerd telegram'. A translation is present but may cover only the report. Not on DECODE.
- no. 1406 Telegram in cypher from London to the Governor-General of Australia, left untranslated 1902-1903 — Catalogue title says "Telegram in cypher from London untranslated". Code words mixed with clear; Colonial Office cypher and code books of the period are held by NAA (A12000, A11804 1912/23 Cypher R 1903 ed., B197, A9553 Decypher CO1 1922). Not digitised.

- no. 1497 Raul Pilla papers (NUPERGS): cipher letters and telegrams of the Frente Única exiles 30 Nov 1931 - 20 Jul 1933 — NUPERGS summaries give gists, so the clear parts at least were read; the cipher parts may not be. Not on DECODE.
- no. 1498 'Conceição', Brasil Viana, Santos → Anacleto Firpo and Urbano Garcia, cipher and code messages from Artigas (1924 rising) 12 Nov - 8 Dec 1924 — NUPERGS: 'Telegrama cifrado' with no content. Not on DECODE.
- no. 1541 Robert Walpole (Paris) → Sir John Goodricke (Stockholm), 5-page letter on Franco-British relations and the Corsica affair, with part of the letter in cypher 8 Oct 1769 — CHM catalogue (Alma/Primo) notes 'Cypher for portion of letter'; no decipherment is mentioned. Not on DECODE (known.py: no hits for Walpole 1769/Goodricke 1769). Goodricke's own papers (Bodleian) are reported to hold cypher letters with transliteration, so a decipherment of this exact letter may exist in another set.
- no. 1635 Rat Johann Christoph von Cobe's mission to Friedrich III of Holstein-Gottorp for Landgrave Johann of Hesse-Braubach, with a ciphered 'Pronota' 1644 — Finding aid: 'Chiffrierter Brief', digitised. No key.

- no. 77 Unknown sender to unknown recipient 4 Aug 1728 (docket) — The whole 205-sign text: not a simple substitution (IoC 1.07), mono, periodic and Quagmire anneals failed. Blocker: too short, no key; needs the key or the sibling letters (dockets 31 Aout, 5 8bre).
- no. 320 Rohan's Valtellina cipher letters of 1636 (d'Émery; Savoy and Canisy), Français 5190 25 Jan – 27 May 1636 — The manuscript ciphertext of Français 5190 nos. 214-215 (Savoy/Canisy) and nos. 171-172 (d'Émery 25 Jan 1636 and Rohan's reply, emery1636) has not been seen: the Gallica scan ends at p. 80; needs BnF images.
- no. 647 Telegrams from the battleship Schleswig-Holstein to a naval officer's family (Dabis) in Kiel, four 55-letter cryptograms 6 Jan 1939 and three later dates (11 Jan, 16 Feb, 13 Mar, years 1937-42) — Unsolved per Schmeh (2017, 2021 posts; WWII list part 1). Transposition suspected from letter frequencies (Gillogly, readers). Lasry was working on them in 2021; no solution reported.
- no. 219 Robert Fagel (1771-1856) (The Hague) to Prince William V, (1746-1805) 18 Jun 1804 — The whole letter (R2238) is not deciphered: no key; the codebook is most likely in the undigitised KHA A31-902.
- no. 223 W.B. von der Hellen (The Hague) to Frederick II of Prussia, 15 April 1763 15 Apr 1763 — R1046 (15 Apr 1763) not deciphered; no key or crib; whether it shares a code with the other 1763 letters is not established.
- no. 339 Military news for Prince Carl August Friedrich of Waldeck, in a three-digit code 18 Jan 1744 (from the reply on f. 4v) — The whole letter: not deciphered. Two-part nomenclator with no key on Arcinsys, HCPortal or DECODE; synthetic controls show one letter is too little to rebuild it; possible key or copy in undigitised HStAM 118 a Nr. 1973-1980.
- no. 632 Union Army cipher telegram books: press copies and registers of telegrams sent and received in cipher 1864-1868 — Series titles only; no statement of decipherment. Union route ciphers (War Department cipher books nos. 1-12) are well documented and these books were normally kept with plain text, so most will be read; post-war RG 393 press copies may hold ciphertext only. RG 393 and RG 107 are also walked by the nara_military sweep: dedup at merge. Not on DECODE; not in the repo. 27 Oct 2026 (targets/union1864/): attempted; only RG 107 item 3854723 is online: Butler to Lt. Col. Biggs, 24 July 1864, route cipher with the Telegraph Office worksheet; route reconstructed, worksheet and the Official Records print (Ser. I vol. 40 pt. 3 p. 432) agree. RG 107 (rest), RG 108 and the three RG 393 series (= catalogue 680) are not digitised. RG 107 telegrams carry their deciphering worksheets and RG 108 holds fair copies, so most are read and largely in print.
- no. 666 Coded messages in German POW letters and the cipher system of German POWs in US camps, 1942-1945 1942-1945 — Censorship found coded passages in POW mail; one file describes the system (so at least part was understood), the Navy file holds the messages. Whether all were read is not stated. Not digitised.
- no. 712 Duisberg code messages: enclosure to an Office of Alien Property litigation case file c. 1942-1978 (parent series dates; Duisberg v. Markham litigation) — Catalogue title only: 'Duisberg Code Messages', filed as an enclosure to an OAP litigation case. Whether a decoding was filed with them is not stated. In the same record group, seized commercial code books (Mitsui San Francisco, naId 6883834; Chemnyco Inc., naId 6850950; Mitsubishi Shoji Seattle 'Cyphers / Meanings', naId 6837958) could serve as keys. The OSS Safehaven reports (RG 226, M1934) mention I.G. Farben code telegrams sent via Chemnyco. Not in catalogue.json (known.py: no hits for Duisberg).
- no. 714 Soviet consulate Hakodate (Kiselev) and trade offices: five-digit-group cipher telegrams copied by the Hokkaido police, 'meaning unknown' 22 Oct 1929 – 15 Nov 1929 (cover letters to 1930) — Hokkaido governor's cover letters to the Home and Foreign Ministers say the consul sent cipher telegrams 'of unknown meaning' from the Hakodate post office; the groups are copied out. No key, no decipherment, no Japanese reading in the file. Not on DECODE (checked 27 Oct 2026). The Japanese Army obtained a Soviet trade-mission code in Sept 1933 (C01004002600, 155 frames) which may belong to the same family: key lead, not yet looked at 28 Oct 2026: Brice Dudout tried it and closed it on his side: over 217 groups the distribution is flat, with no repeats and no usable depth (tested against 2,000 controls), so he reads it as a one-time additive. Not checked here.
- no. 764 Henry Clinton's Gibraltar notebook (Notebook B), observations with some entries in cipher 1771 — Finding aid: 'For unclear reasons, he wrote some entries in cipher.' No decipherment noted. Not on DECODE, not in the repo (known.py 'Clinton Papers' hits only the d'Estaing 1779 target).
- no. 766 Davis E. Castle, Signal Corps officer's journals with two coded passages 1 Nov 1864; 25 Aug 1865 — Finding aid: 'The pages dated November 1, 1864 and August 25, 1865 contain coded passages.' Subject heading Ciphers. No decipherment noted.
- no. 806 Arthur Mainwaring → Lord Coningsby, letter (cipher matched) 2 Oct 1712 — Found by the cipher-family queries in Quicksearch (the matching note sits on archives.yale.edu, which returned 403, so the cipher is not confirmed). Not digitised, not on DECODE, not in repo. Yale finding-aid PDF (3 Nov 2026): "Some use of cipher." Confirmed cipher.
- no. 809 William Blathwayt → John Robinson (envoy in Sweden), four drafts and a copy (cipher matched) 9/19 Aug - 6 Dec 1698 — Found by the cipher-family queries in Quicksearch (the matching note sits on archives.yale.edu, which returned 403, so the cipher is not confirmed). Not digitised, not on DECODE, not in repo.

Not digitised online (no 856 link in the MARC record). The same fonds holds 142 cipher telegrams of 1879-1886 with transcriptions attached and two key sheets: A3039 "Código para escribir en clave" (ca. 1880) and B4931 "Claves telegráficas a utilizar con Lynch, Altamirano, Novoa y todas las legaciones chilenas en el extranjero" (ca. 1883, 10 p.).

Not digitised online (no link in the record; BND search finds no scan). Not on DECODE, not in the repo (checked 28 Oct 2026).
- no. 1529 Colombian telegraph administration: copies of international telegrams (Guayaquil, Lima, London, New York, Rome, Barcelona, Manchester, Mexico ...) mostly in letter code 1907-1908 — AGN description: most of the telegrams are "en clave (letras)".

- no. 659 GC&CS Cryptographic Co-ordination and Records section: file of "Unsolved Problems", 1944 1944 — Catalogue title names it as a file of unsolved problems kept by the British CCR section (which logged unidentified and unread systems). Not digitised (no digital objects). Contents may be mostly machine or one-time traffic; hand systems among them unknown. Not on DECODE. 27 Oct 2026 (targets/ccr1944/): attempted; NARA catalog API: file unit, loose sheets, container 164, College Park; no scope note, no digital objects.

The 1932 entry shows the papers were used in the Black Tom / Kingsland sabotage claims. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 713 AEF G-2 Radio Intelligence Section: intercepted German messages and worksheets on the solution of enemy codes and ciphers, 1917-18 1917-1918 — Series title only; the descriptions give no scope note. The AEF G-2 A-6 section worked on ADFGX/ADFGVX, the KRU/Schlüsselheft trench codes and the German field codes; many of those systems were broken only for some days or keys (Painvin, Childs), so an undecoded residue is likely but not stated. Not in catalogue.json (known.py: no hits for the naIds, 'Solution of Enemy Codes' or 'Radio Intelligence'); the repo's targets/adfgvx covers the Eastern Front messages printed by Childs, not this file.
- no. 759 German, Japanese and French Legation code telegrams at La Paz, copied by informers for the US Legation, which the FBI could not decipher Oct 1941 - Jan 1942 — Found in the slice L word-hit triage (agent_59.md) and confirmed from the purport list OCR (fetched 27 Oct 2026). Blocked on access: the 1940-44 decimal file 862.20224 is not digitised (only the purport lists are online). Dozens of telegrams were copied; the FBI returned the German Legation copies unread in Dec 1941, and only one of 79 later messages is noted as decoded. The German diplomatic systems of 1941 (Floradora and others) were partly read by GC&CS, so some texts may survive in HW 12; these US copies were not read. Distinct from catalogue 687 (two La Paz radiograms on MID cards, 1940-41). known.py: no hits for 862.20224.

Not checked against the original or other editions; no DECODE check made (calendar entry, not a DECODE record). Royalist cipher traffic (Nicholas/Hyde/Ross/Pile); research/ia_meta/candidates.json has an aggregate row for the 1655-56 Commonwealth letters, so on merge this item-level row should replace or sit under that aggregate, not duplicate it.
- no. 999 Dr. Wotton to Queen Mary: letter partly in cipher, calendared as undeciphered (CSP Foreign, Mary, 1553-58) Jan. 4 (calendar of CSP Foreign, Mary, 1553-58) — Printed calendar says cipher not deciphered ([A few lines in cipher, undeciphered).

- no. 1018 The Emperor Charles V to the Abbot of Najera: almost entirely in cipher, torn, scarcely half legible, no deciphering appended 16 Nov 1526 — Calendar footnote: only the readable half is printed; sibling letters of the series are deciphered by the editor.
- no. 13 Anonymous to the Duke of Mercœur 'ce xxvj juin' [c. 1586] — All six cipher runs (217 signs of 55 kinds: Greek letters, squares, digits). Too short for ciphertext-only; needs a sibling letter or the key.
- no. 66 A Venetian secretary to the Venetian ambassador in England, 1625, in a three-figure syllabic code (SP 106/10 ff. 193-195) first half of 1625 — The code groups (420 tokens, 117 types) undeciphered; annealing does not converge. Blocker: no key; another letter in this code would be needed (ASVe or TNA SP 99, not online).
- no. 127 Burghley to Walsingham (letter-book copy) 5 Jul 1572 — Codes [2], [4], [5], the monogram, letters A and F, and the five-sign run 'm o R. d A.'. Blocker: no key known; items too few and short.
- no. 129 Walsingham to Burghley, Lyons, 25 June 1571 (letter-book copy; Queen's instructions to Walsingham follow, clear) 25 Jun 1571 — The nine-sign run and codes [12], [E4] in Walsingham to Burghley. Blocker: too short, no key; the sent original in TNA SP 70 (CSP For. ix 1821) is not online and may carry a decipherment.
- no. 350 William, Baron Craven, to Prince Rupert, The Hague 6 Nov 1648 — The cipher of the 6 Nov 1648 letter: not transcribed or deciphered; Tomokiyo says it differs from the volume's known ciphers; Add MS 72438 and 1648-49 royalist keys not yet tested on it.
- no. 356 British consul at Lüderitzbucht to the Foreign Office, coded telegram (43 five-figure groups) 9 Oct 1911 — All 43 five-figure groups: not deciphered; the FO/consular code of 1911 (and any additive) unidentified; the decyphered copy in TNA FO 367/371 not sought.
- no. 372 Philip IV → the marquis of Velada, ambassador extraordinary in England: two short cipher runs 17 Dec 1640 — Viewed 25 Oct 2026: clear Spanish recalling Velada to Flanders, with two short cipher runs (figures 4-171, signs, syllables), no decipherment, nothing on the dorse, no print found. Too short for a break; needs the 1640 Velada/Malvezzi cifra (Simancas, Estado, Inglaterra). 27 Oct 2026: assessment confirmed, too short to break without the key; the 1640 England papers of Simancas (Estado, Inglaterra) are not on PARES.
- no. 443 Unknown correspondent, cipher letter, 31 July 1662 (Sanguszko archive) 31 Jul 1662 — DECODE R7513 (status N/A, cipher type unknown, private ciphertext, uploaded by the Archiwum Narodowe w Krakowie 2023; no key or decryption file on the records).

Havelland, Aug 1940, filed without clear text 1938-Aug 1940 — Not on DECODE, not in the repo. The W.f.S. is a commercial-code (Hapag-Lloyd) dictionary with a columnar 'Kammwürfel' step; several telegrams in the same rolls are filed with their clear text, so the code list and the transposition can be rebuilt from pairs; the two 1940 radio telegrams have no clear text with them.
- no. 765 Peter H. Musty, diaries with personal names and two and a half months of entries in a numerical substitution code 2 July - 16 Sept 1864 — Finding aid: 'wrote personal names and the daily entries for July 2- September 16, 1864, in a numerical substitution code.' No decipherment noted.

- no. 1083 unsigned letter in cipher -> not stated, letter in cipher without sender or recipient c. 1500 (undated) — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume N-23 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 1535 Political Resident Bushire, Muscat and others → Political Agent Bahrain, telegrams in Government Telegraph Code / Indian Word Code 18 Oct 1918 - 16 Mar 1926 — Not on DECODE. Catalogue: 'copies of telegrams written in cypher, some of which have the decoded words written above in pencil'. IOR/R/15/2/1466-1467 hold Indian Word Code 1924 supplements (addressee code words only, as sampled)
- no. 1538 William Eustis (Secretary of War) → Gen. James Wilkinson, routine letter with part of the message in cypher 10 May 1809 — Calendar entry in the finding aid (p.29 of 49): 'Routine: officer transfers; part of message in cypher'. No decipherment noted. The neighbouring item 91 (4 May 1809, Eustis, 'receipt of ciphered message') is the preceding cipher message. Not on DECODE as far as checked.
- no. 121 "L'Estat du Roy de Navarre et de son party en France" (unknown author) after 1580 — Ten nomenclator numbers (6, 21, 26, 36, 51, 57, 72, 81, 99, 721) and about 5% of the text illegible; most sentences keep holes. Blocker: no key material.
- no. 262 Farnese chancery cipher, Spagna 1A (IA-1, DECODE R91), companion of Vatican Challenge Part 5 Dec 1541 (letter on the Nuremberg diet and Buda) — R91 (Dec 1541) not deciphered and not attacked: a different key and design from IA-2, so Klee's key does not transfer; no key sheet or decipherment on the record.
- no. 377 Van Wijngaerden, Copenhagen, to the States General: three letters partly in cipher, 1671-1672 (inv. 12586.93-.94) 1671-1672 — NA catalogue: partly in cipher.

- no. 661 Raphael Pino Roca → Primitivo Yella, coded message, 1942 13 Nov 1942 — A private coded message referred to the Army cryptanalysts in 1942 (censorship or FBI case, by its filing). Whether SIS read it is not stated. Not digitised.
- no. 664 Cipher forwarded to MI-8 by Major Mauborgne, 1917 7 Dec 1917 — A cipher sent to MI-8 for solution; outcome not in the title. Could be a proposed US system rather than an intercept. Not digitised.
- no. 667 Peruvian coded dispatch (1935) and coded message of the commander of the Peruvian submarine division 7 May 1935 — Intercepted Peruvian code traffic held by SIS; no solution indicated in the titles. Not digitised.

Whether any coded item stayed unread is not stated. Not digitised. Not in catalogue.json (known.py: no hits for the series or naIds).
- no. 718 Cipher samples and translations submitted to the Chief Signal Officer, 1861-69 1861-1869 — Series description only. Samples are said to come with translations, but whether every sample is paired is not stated; some submitted specimens (Civil War inventors' systems, possibly intercepted or captured pieces forwarded to Myer/Fisher) may lack one. Not on DECODE. known.py: no hit for the naId. The RG 111 "Intercepted Letters" series (naId 2668866) is already covered and was not re-added.
- no. 719 Letters written in cipher held by Carl Reissman, alien enemy detained (N. Illinois), 1917 27 Dec 1917 — Index slip only; no sign in the slips of a decipherment. Whether the letters were sent to MI-8 and read is unknown. known.py: no hit for Reissman.
- no. 720 Code message found on Edmond DeSalm Horstmar, South Carolina, 1918 5-12 Apr 1918 — Index slip only; no reading recorded on the slip. known.py: no hit for Horstmar.
- no. 760 Code messages of Dr. Otto Joseph (Transocean News Agency, Lima) examined by the FBI laboratory and not decoded, 'as cipher tables are not available' 1941 (FBI report 1 Nov 1941; Lima despatch #741, 19 Nov 1941) — Found in the slice L word-hit triage (agent_59.md) and confirmed from the purport list OCR (fetched 27 Oct 2026). Blocked on access: the 1940-44 decimal file is not digitised. The FBI laboratory had the code messages and no tables; nothing in the purports records a later reading. Amount unknown. known.py: no hits for Otto Joseph.
- no. 773 Intercepted letters between French diplomats and French ministers, 1767-1768 (24 items), Shelburne papers vol. 35 1767-1768 — Finding aid gives only the title; probably Deciphering Branch decrypts sent to Shelburne as Southern Secretary. Whether ciphertext is present is unknown.
- no. 802 Earl of Orrery → Earl of Danby, Bath, two letters (cipher matched) 23-24 Jul 1674 — Found by the cipher-family queries in Quicksearch (the matching note sits on archives.yale.edu, which returned 403, so the cipher is not confirmed). Not digitised, not on DECODE, not in repo. Yale finding-aid PDF (3 Nov 2026): "Written in cipher with 1p. key"; the scope note says Danby decoded the cipher and wrote the key, which is with the letter. So it was read at the time; a removal candidate.
- no. 851 Riverbank Laboratories 'Mexican codes' and unsorted cryptographic papers (the surviving Riverbank Department of Ciphers files) 1917-1918 — Friedman's own accounts (NSA Friedman papers, folders 433/513) say Riverbank worked codes and ciphers forwarded by State, War, Navy and Justice in 1916-20; a 1917 Army note quoted in a web search summary says the main work was Mexican messages (source PDF not opened). Friedman wrote in 1948 that the Riverbank cipher records were thought destroyed after Fabyan's death (Cora Tyzzer letter, NSA A69876) and that the LoC Fabyan collection held none of them; the NYPL boxes came via Fabyan's widow to George Curtis (gift 1960), so these two boxes may be the only survivors. MI-8 broke several Mexican government codes in 1917-19 (repo: research/nara_triage_c/e), so many messages will be read; whether any are unread is unknown. Schmeh (2018) saw three boxes, not these. NSA historians (Dave Hatch and a colleague, a November visit, year not given) went through all nine Riverbank boxes and found them 'very duplicative and mixed': page proofs of Riverbank publications, student folders and exercises on graph paper, a few Parker Hitt letters; no cipher intercepts are mentioned (NSA blog 'A great TDY', Doc ID 6919113, released 30 Mar 2026).

Not on DECODE.
- no. 152 Pandolfo Malatesta, archbishop of Patras, to Gianfrancesco Gonzaga 22 April 1428 — The three cipher runs (262 signs): not mono- or homophonic in Latin or Italian; the R1853 Malatesta keys do not fit. Likely key material, Pandolfo's 1438 letter with its translation (ASMn), is not online or printed in cipher.
- no. 449 Unidentified cipher letter, Kraków UNK 1 1748 (21 [month] 1748; pencil: Lubienski) — DECODE R7466 (status N/A, cipher type unknown, private ciphertext, uploaded by the Archiwum Narodowe w Krakowie 2023; no key or decryption file on the records).

- no. 36 King Frederick II (the Great) of Prussia (1712-1786) (London) to Louis Michell (1712-1786), Prussian resident in London 28 Dec 1751 — 265 of 360 groups without a value; no sentence builds. Blocker: no key material (needs more decipherments in this code).
- no. 213 Comte d'Affry (The Hague) to the Marquis de Stainville (Choiseul), ambassador at Vienna, intercepted code letter 7 Aug 1757 — R1071 (7 Aug 1757, 761 groups) not deciphered: a separate code C, no decipherment on the images, no key on DECODE; the NA 1.01.50 inv. 221/223 decipherments are not digitised (affry1757c).
- no. 230 Lodewijk van Toulon (1767-1840) (The Hague) to Dirk van Hogendorp (1761-1822), ambassador of the Batavian Re[ublic in Russia 30 Jul 1803 — 64 of the 67 text groups of R2034 not deciphered: the key survives only as a physical booklet (NA 2.21.045/34313), not digitised (toulon1803).
- no. 582 Bavarian envoy Mörmann in Vienna, reports partly in a large numeric code (drafts 1733 and German reports 1731-35); the finding aid's cipher table is not among the scans 1730-1735 — Checked image by image by Michael Brackx (issue #123, 27 Oct 2026; image 102 of Wien 215 confirmed here): no cipher table and no decipherment in either digitised file. The finding aid's 'Chiffrentabelle' was either not filmed or is a wrong description. Code of about 4,300 values, keyless; the clear context around each group could fix frequent groups but not give a full reading.
- no. 687 German Legation telegrams, Central America 1940-41: Chargé Tripeloury (San José) ↔ Minister Reinebeck (Guatemala), La Paz → Berlin radiograms, Havana → Berlin Dec 1940-Aug 1941 — Cards: the US attaché sent copies of the cipher telegrams 'to be decoded', saying there were 'no facilities here for breaking Ger. codes'. MID records no decode. German diplomatic traffic of 1940-41 (the Auswärtiges Amt systems) was later read in part by GC&CS and the US (Floradora and related systems), so these copies may match decrypts in RG 457. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 705 British consular cipher telegrams (Vigo → Foreign Office 1939; Gibraltar ↔ British consul Las Palmas, Lisbon/Lagos → consul Tenerife 1940), copies obtained by the German naval attaché Madrid and sent to OKW/Chi Oct-Nov 1939 and Apr 1940 — Not on DECODE, not in the repo. The covering letters submit the copies 'zwecks möglicher Auswertung'; no decipherment or Chi reply is filed with them on these frames. British consular traffic of 1939-40 was in hand book ciphers (figure codes with subtractor tables); the system is not identified here.
- no. 1045 Antonio de Fonseca -> the Catholic Monarchs, letter in cipher, now illegible from damp according to the catalogue 14 Jan 1497 — Listed in the RAH Salazar y Castro catalogue (IA full text) as cipher with no decipherment or translation noted in the entry. Volume A-11 is not among the Salazar volumes on DECODE (only 9/8, 9/17, 9/23-9/31, 9/34 appear). Ferdinand's secretariat: the Catholic Monarchs' cifra general (known from Galende Diaz 1994, Parisi 2020 and the esp318/garcilaso1498 targets in this repo) may apply.
- no. 137 Abraham Cowley's hand ('Mr. Conleys Hand'), Paris, to a royalist in Holland, 2 letters 28 Dec 1652 – 3 May 1653 — The 23 code numbers in five runs (names, a place). Blocker: too few for ciphertext-only; needs a Jermyn/Queen key of 1652-53.
- no. 721 Letter in cypher from Leavenworth, Kansas, in the Jack Downing (Cherokee) file, 1916 4 Jun 1916 — Index card only; nothing says it was read. Leavenworth suggests a federal prisoner's letter. known.py: no hit.

- no. 70 Letters to Mr Carré, Pall Mall, 1742–45, 3 ciphertexts Mar 1742 – 19 Jan 1745 — All three letters. Blocker: no key, gloss or crib; a random-order code of this size cannot be rebuilt ciphertext-only.
- no. 193 Bayard to Montmorency 5 Jan 1526 — The three cipher lines (56 signs of 29 kinds). Blocker: no key, too short; needs the original (V. 41 f. 4).
- no. 206 Murberg, Johan, Görtz, Georg Heinrich von to unknown recipient 1717 — All five cipher passages (809 groups). Blocker: no key; ciphertext-only failed even on a synthetic control; needs Görtz's German chancery key (Riksarkivet).
- no. 353 Duke of Ormond to the Earl of Arran, short passage in code ('a trial whether you are skilful in deciphering') 24 Jan 1677/8 — All 20 numbers: not deciphered; the 1678 Ormond-Arran code is not rebuilt and the manuscript (Ormonde papers, NLI) is unlocated; very short.

- no. 683 The "Gulick message" signed "Honytre", still unsolved at Riverbank in Oct 1917, and the cipher letter found on Thomas Gulick Sept-Oct 1917 — Name-index cards: Riverbank (Fabyan) reports the 'Gulick message' signed Honytre still unsolved (10020-69, 2 Oct 1917). The same Riverbank card run lists monthly reports of 'undeciphered messages' (10020-64). Gulick held a suspicious cipher letter (9140-1369). Not the Tampico message (entry 674, 10020-60). The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 686 Document dug up near a post, believed to locate the James brothers' loot and signed 'Frank James': War Department cryptographers found no solution dug up 1931; MID correspondence 3 Sept-7 Dec 1931 — Card read 2 Nov 2026: the Chief Signal Officer first gave an 'interpretation' (15 Sept 1931, memo in the file, not online) giving the location of some gold; the cryptographers then reported no solution and thought the cryptogram not authentic (7 Dec 1931). Place: 'Rio Grande county'. Document found near an Army post (Indian Territory story).
- no. 688 Letter and map from 'Agent Pfeiffer' in signs taken for Slavic or Hungarian shorthand; MI-8 could not read them 21 Feb 1918 — Card read 2 Nov 2026: Agent Pfeiffer wrote from Columbus, Ohio (forwarded 14 Feb 1918); the Cipher Bureau returned the letter and map on 21 Feb 1918 unable to add anything to the informant's remarks (signs said to be Slavic or Hungarian shorthand).
- no. 689 Intercepted letters in code from the Panama Canal Zone, including one to D. V. Kracker, Bogotá, that MI-8 could not decipher Feb 1918 — Card read 2 Nov 2026: besides the Kracker letter (4131-156) the Cipher Bureau also could not decipher a code message in a letter to A. Held (4131-155, 2 Feb 1918). The Lorenzo Garcia letter (4131-163) is a stamp-denomination code judged only fit for short simple messages; 4131-158 (Banco Aleman Transatlantic) got a probable decipherment.
- no. 700 Austrian E. Kovacs, Valparaíso, to Buenos Aires: code messages (and Nunezant -> Morluk, Iquique), translation requested 23 Oct-21 Nov 1917 — Cards: translation of the messages requested; no result recorded. The same file holds German bank cables to South America (Banco Germánico). The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 701 Letter from 'German Mexico' to Sam Becer, Havana, 'in unknown code, may be a German spy letter' 12 Jan 1918 — Card: letter held; Becer said to correspond in code with Sobel at Buenos Aires. No solution recorded. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 702 Letter in cipher addressed to Cornelius K. Bettman, Barcelona, with a map thought to be of Havana harbour 1 Apr 1918 — Card read 2 Nov 2026: file P.F. 1444 runs 1 Apr 1918 to 17 Mar 1919 with no decipherment recorded; later items are a Havana harbour sketch and defences blueprint (7 May 1918) and the addressee not found at Pino 5, Barcelona (21 June 1918).
- no. 703 Code message to the Swiss consul at San Francisco; Weiskopf: 'almost impossible to decode a single message' 24 Mar 1917 — Case-file letter (OG 3337, 24 Mar 1917, Bureau to H. B. Hook, Nogales, Arizona): Victor Weiskopf, the Bureau's code expert, said one message could hardly be deciphered (it might be German, French or English) and asked for others in the same code. The message text was not found in the OCR of this roll; the Nogales report should carry the copy.
- no. 710 Chicherin → Sukhanov (Vladivostok Soviet): telegram on routing Allied consular telegrams via Moscow, with code passages unread by AEF Siberia 4 May 1918 — AEF Siberia memorandum: 'The code and cipher section inform that they are not in position to solve by inspection the short passages of code contained in the message'; the key was presumed destroyed with Sukhanov's papers. The ciphertext itself is not on the reel; it may survive in the MID copy (RG 165) or the AEF intelligence files. The same memorandum describes 18 Allied telegrams (16 American, many 'wholly or partly in code') abstracted from the Vladivostok telegraph office; those are US/Allied traffic copies, not a separate candidate. Not in catalogue.json (known.py: no hits for Chicherin, Sukhanov).
- no. 852 Sisson documents: memoranda on translations and code messages found with the documents (Samuel N. Harper Papers) 1918-1920 — Finding aid: 'Memoranda on translations and code messages found with the Sisson documents (1918-1920)'. No cipher text or decipherment described. Not on DECODE; known.py finds the Sisson documents only as a cross-reference in an NARA triage row.
- no. 998 Burlamachi / Woodford group, 12 July 1620: letter partly in cipher, calendared as undeciphered (CSP Domestic James I 1619-23, p. 171) July 12 (calendar of CSP Domestic, James I, 1619-23) — Printed calendar says cipher not deciphered (the Prince of Condé, offering the daughter of France in marriage to the Prince. Partly in cipher, undeciphered). Not checked against the original or other editions; no DECODE check made (calendar entry, not a DECODE record).
- no. 1004 Letter from Brussels with last paragraph in cipher, "undeciphered" (CSP Domestic Elizabeth 1595-97, p. 56) 12 Jun 1595 (Brussels) — Calendar says "the last paragraph in cipher, undeciphered". The Spanish/boors and Cardinal of Austria news fixes the date June 1595.

No decipherment noted.
- no. 75 Trigram code fragment 'Suite du No 13 / No 24' undated — All 77 groups. Blocker: too short for a large or enciphered code; needs the key or the rest of the series (probably unimaged ff. 4-54).
- no. 357 Intercepted letter from Brussels with three short number runs 3 Apr 1660 NS — All three runs (21 numbers): not deciphered; too short for a contextual guess; partial tables do not exclude their families; the Rawlinson A 67 leaf not checked for a gloss.

- no. 1348 Cipher jottings ("varie scritture cifrate") among pen trials on the end leaves of a Trivulziana codex 15th-17th century (codex 1401-1415) — Manus Online (CNMD 0000050114): "Probationes pennae e varie scritture cifrate dei secc. XV-XVII alle cc. 221v, 222v". Not viewed; Trivulziana site unreachable from here. Not on DECODE.
- no. 1414 Defence censorship: Mr Stiver, use of a secret code 1943 — Catalogue title only. Whether the code text is on file is unknown.
- no. 1522 Antonio Huneeus Valdés (Paris) → Chilean government: telegram in cipher on the Upper Silesia plebiscite 23 Mar 1921 — BN Chile catalogue: 'Telegrama escrito en clave'; the summary (opinion on the Upper Silesia plebiscite) suggests a decipherment or plain draft exists alongside. Not digitised online (no link in the record; BND search finds no scan). Not on DECODE, not in the repo (checked 28 Oct 2026).
- no. 670 Intercepted Russian (Soviet) coded messages, 1931-1932 1931-1932 — SIS-era intercepts; Soviet systems of the period were mostly additive codes or one-time pads, so this may be out of hand-cipher scope. Not digitised.
- no. 685 Nauen wireless code message that MI-8 judged 'not in any German code known to us' and indecipherable 13 May 1919 — Card: the Director of Naval Communications sent a Nauen code message to the Chief of Staff. Yardley's memo says it is 'not in any of Ger. codes known to us & is indecipherable'. Other Nauen intercepts of 1918 (10531-51, -103, -163; 4131-526, 25 messages) were deciphered. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 693 Soviet Baltic Fleet radio cipher messages (five-figure groups) copied by the US military attaché at Riga 4 and 24 Aug 1928 — The OCR of the frames gives the groups (read from NARA's OCR, not the image). The attaché's report gives call signs, key names and his guess at the content ('probably reports her location'). No decipherment is filed.
- no. 706 French consular agent Las Palmas → Marine Casablanca, letter-cipher telegrams ('Nota num. 2-4') copied by an anonymous informant for the German naval attaché Madrid 22-28 Apr 1940 — Not on DECODE, not in the repo. Submitted to OKW Ausland IV for 'mögliche Auswertung'; no decipherment on the frames. French naval traffic of 1940 used code with letter superencipherment; system not identified.
- no. 716 Japanese Navy numeral telegram to HMS Newcastle sent by Otoshi and Yokosuka radio stations, 38 five-digit groups 20 Aug 1914 — The record text gives the instruction to pass 'a numeral telegram' to Newcastle and then the groups. No key; likely a Royal Navy or joint Anglo-Japanese code, which would be outside this repository. Not viewed, not on DECODE
- no. 404 Telegram in cipher from the Portuguese consulate in Cape Town to the Minister of Foreign Affairs 1904 — DigitArq: telegram in cipher; no decipherment noted. Not digitised; not on DECODE.
- no. 684 O. G. Roth, Cape Haïtien, to Elder G. G. Roth, New York: letter of 24 five-figure groups the postal censor could not decipher 22 Aug 1918 — Record card: New York postal censor report, 22 Aug 1918, 'contains twenty four numbers of five numeral each; unable to decipher'. Later entries to the Port-au-Prince postal inspector, the State Department and ONI record no solution. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 690 Message concerning Mrs Anne Balmforth: 'seems to be a code, Cipher Bureau can do nothing with it' 21 Feb 1918 — Card read 2 Nov 2026: the card spells the name Balmforth (not Belmforth); the Cipher Bureau did nothing with the enclosed message because it 'seems to be a code' (21 Feb 1918).
- no. 695 Luisa Castellanos, Matanzas, to R. V. Heredia, Venezuela: letter partly in code; MI-8 reported 'insufficient material to give coherent reading' 16 May-9 Oct 1918 — Cards: the cryptographers reported insufficient material for a coherent reading. The MID correspondence file itself (RG 165, entry 65, MID 1917-41) is not digitised; only the index card (M1194/M912/M1474) is online.
- no. 696 'Beatriz' (Arizona) to Manuel Loya, Mexico: suspected cipher letter that MIB called 'impossible to solve' 7-15 May 1918 — Card read 2 Nov 2026: MIB (Manly) said on 15 May 1918 it was impossible to solve such puzzles without the exact form and location of the letter, offering to read the flap inscription; on 25 May 1918 it returned the original and advised that the flap letters were likely initials of a religious invocation. The letter text itself was not read.
- no. 792 A 16th-century book 'allegedly in cipher' that Major Rhea M. Smith (Rollins College) was trying to solve c. 1953 — Read 28 Oct 2026 (OCR): WFF lends Smith manuals and hopes he is 'on the right track toward a complete solution'. The book is unidentified; probably a hidden-cipher claim of the Baconian kind.
- no. 1303 Adventure magazine, 'Ask Adventure': 90-digit numeric cryptogram sent in by T. F. Ridell, found in old papers July 1934 (Ask Adventure column, p. 124) — Unsolved per Schmeh (Cipherbrain 22 Apr 2018, revisiting a 2015 German post); analyses by Stefan Wagner and Norbert Biermann found nothing; a reader's 'Poe codebook' solution was built to fit and was rejected in the thread. Not on DECODE. known.py: no hit.
Numbers that have left the catalogue
198 catalogue numbers as of 4 Nov 2026, with the write-ups that took them out and the day each landed. (part) marks a split entry: that piece has an outcome, and any piece still open stays in the table above under its number.
About the catalogue
What is still in cipher in the digitised diplomatic volumes, and nobody has read. The first entries came from the French volumes on Gallica; the rest (45) from the DECODE database, every ciphertext record it marks non-decrypted or partly decrypted, grouped into letters and series and checked against this repository's own targets and Tomokiyo's list. A sweep of 22 Sept 2026 added candidates for new solves and outside reads: DECODE records never classified, letters Tomokiyo calls undeciphered while naming a key, Gallica notices and the printed calendars. On 14 Oct 2026 open items were pulled from Satoru’s Cryptoole index and checked against the repository. 1015 entries are counted targets, 14 are noted only. Class A means siblings with decipherment in the same volume, B a partial key or known family in print, C no key and no sibling. Entries read, partly read, resolved or found already in print are taken out of the catalogue and written up; those attempted here without a reading stay, tagged attempted, open. An entry a target folder is working on now is tagged in progress, read at each rebuild from the head of the folder’s NOTES.md, and its page links those notes.
Scores are judgements from catalogue descriptions and the literature, not from the leaves: 175 of 1029 entries have been viewed on the image, and each page carries the check that would confirm it is open. Data: catalogue.json · text: CATALOGUE.md · how to send a result: contribute.
How the scores were set
Importance asks what a full reading would add: 5 for a first-hand report of a major event by a principal witness (du Bellay in London 1529, Lanssac at the Polish election), 2 for routine business. Solvability asks whether the material online is enough: 5 when deciphered siblings of the same hand and year sit in the same volume, 1 for one short letter in an unknown language. Difficulty is the technical work at the keyboard: 1 for aligning a known sibling, 5 for a statistics-only attack on a large homophonic nomenclator. The default priority weights importance 0.4, solvability 0.35 and ease 0.25 (ease is 6 minus difficulty), rescaled to 0–10; change them under “More” above the table. Every score is a judgement made before viewing the leaf, so treat the order as a work plan, not a finding.
Checked: catalogue descriptions and item numbering; presence or absence of a decipherment item in each volume; shelfmarks from the IIIF manifests. For the DECODE entries: the record metadata and notes, key records from the same archive series, overlap with this repository's targets and with Tomokiyo's list. Entries tagged rule-scored were scored by a script from DECODE's metadata and not yet reviewed by hand. Verify each entry on the image and in the literature before attacking it.
