- The telegrams
- Fourteen telegrams of June 1916 (N02, N08, N11, N12, N14, N19a, N19b, N21, N24, N25, N28, N36 and, from volume 4, V4B and V4D), 1,306 four-digit groups: eight from Tokyo to Shanghai (Huang Xing, Zhang Xiaozhun), six from the Shanghai group to Tokyo. Most are dated 8 to 16 June.
- Where
- Diplomatic Archives of the Ministry of Foreign Affairs of Japan, via JACAR: B03050089200, B03050089300, B03050089400, B03050089500 and, for V4B and V4D, B03050089900. Telegraph-office forms copied by the police.
- The cipher
- Chinese telegraph code numbers in four-digit groups, each digit replaced through a table for its place, then 0901 added. The first two groups of a form are in clear: 1369 1378 = 容密.
- How it was deciphered
- The key was found by annealing and a single anomaly (借甸 for 借款), with no crib. Ten telegrams read with a key fitted on four, the day code of N14 matches its date, and two telegrams never used in the search read unchanged.
- Credit
- Brice Dudout, with Claude (mainly Opus 5.5): digits re-read on the scans, the key (published 19 October 2026), translations and context. Satoshi Tomokiyo, Cryptiana: the identification of the key as a renumbered 明密 code book, with the page-80 numbering; his section credits the formula to Dudout. This project checked the key with its own decoder.
- What it says
- About ten thousand rifles and some mountain guns bought through a Japanese intermediary for Zhejiang, a loan of a million, and Huang Xing’s warning that a legal solution needs armed force behind it.
- Still open
- 48 characters are kept as decoded but not understood, mostly in N36 and V4B, and 6 groups are illegible; 55 more are probable readings. Only 4 of the 22 sheets of V4B were re-read blind. No copy of the 容密 book has been found.
01 The forms
When Yuan Shikai died on 6 June 1916, Huang Xing was in Tokyo, living at Aoyama Minami-machi 3-53, and his allies were in Shanghai. The Japanese police copied the telegrams that passed between them onto the telegraph office’s own forms, and the copies survive in a Foreign Ministry series of mail and telegrams of watched persons. Each form holds a grid of digits written as kanji numerals. Brice Dudout reads the grid in columns, right to left, each column from the top, and cuts the stream into four-digit groups.
The first two groups are in clear and name the code. Hsueh Chun-tu’s edition of Huang Xing’s 1916 drafts notes a code name at the head of each telegram, one per correspondent. On that evidence 容密 is a code book issued to particular correspondents, and it needed its own key. The same files hold telegrams in two other numeric keys with their own pages: 共密 and 辰密.
| telegram | date, 1916 | direction | groups |
|---|---|---|---|
| N11, N12, N14 | 8, 8, 9 June | Tokyo → Shanghai | 58, 82, 47 |
| N19b, N28 | 11, 14 June | Tokyo → Shanghai | 143, 18 |
| N02, N08, N19a | June (day not read) | Tokyo → Shanghai | 93, 46, 17 |
| N21, N36 | 13, 16 June | Shanghai → Tokyo | 107, 58 |
| N24, N25, V4D | June (day not read) | Shanghai → Tokyo | 200, 113, 59 |
| V4B | 25 June ? | Shanghai → Tokyo | 265 |
| all 14 | 1,306 |
Group counts measured on the transcription. Of the 1,306, 1,198 read without doubt, 55 are probable readings, 48 are unresolved and 6 illegible (Daniel’s rule, counted on reading.md). These four figures add to 1,307, one more than the 1,306 groups, so one group is counted in two classes there. By status in decryption.txt the 1,306 split 1,198 ok, 103 doubtful (55 + 48) and 5 illegible; reading.md marks 6 illegible groups.
02 The 容密 key
Each digit is replaced according to its place, and 0901 is added with ordinary carrying:
| digit | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|
| thousands | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 9 | 0 |
| hundreds | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| tens | 0 | 1 | 9 | 8 | 2 | 7 | 6 | 5 | 4 | 3 |
| units | 9 | 8 | 0 | 1 | 7 | 2 | 3 | 4 | 5 | 6 |
Example. 2081: the thousands 2 and hundreds 0 stay, the tens 8 becomes 4, the units 1 becomes 8, giving 2048; 2048 + 0901 = 2949, 款, “funds”. No group in the corpus begins with 00: the encipherer wrote 90 instead, which is why the thousands 9 stands for 0. So 9084 becomes 0047, and 0047 + 0901 = 0948, 國.
How it was found. The first sheets alone, ninety groups, were too few. Once about 590 groups from the continuation sheets were in hand, annealing four digit tables, scored with a language model of telegraph-code characters, gave readable text. The addition showed itself through one word: 借款, “loan”, sometimes came out 借甸, a thousand too high, exactly when no carry came up from the hundreds. The exact key was computed on four telegrams (N02, N08, N11, N12); the rule 90 = 00 was added from the groups beginning 90.
As a renumbered book. Satoshi Tomokiyo, in the Cryptiana section on the mingmi (明密) format codes, reads this key as a standard 明密 code book with its pages, columns and rows rewritten by hand: pages numbered cyclically from page 10, the tens digit a column number and the units a row. The two descriptions give the same table over all 10,000 values; the repository file key.md states the key both ways. They differ in one cell: written page 80 is page 89 in his numbering and 99 by the formula. The one group concerned, 8012 in N25, reads in neither case; swapping two digits gives 8102, 一, and N25 then ends 一切到乞賜教, “please advise him on everything when he arrives” (of Wu Zhaolian, sent by the Zhejiang governor to meet Huang Xing in Japan). Cryptiana credits the finding that 8012 is an enciphering error for 8102 to Dudout, and Wenmi credits Tomokiyo’s note that it reads in neither version; both are credited here.
Dating. Dudout published the 容密 page, key and eleven telegrams on 19 October 2026 (GitHub commit of the Wenmi repository, 10:11 UTC). Tomokiyo’s section is undated, the page was last modified on 24 October 2026, and Wenmi cites it as of 23 October. The section credits the formula to Dudout (“The formula found by Dudout is to first convert each of the four digits according to a separate respective table; add 901”) and adds the renumbered-book reading.
03 The checks
His checks. The key computed on four telegrams decodes the other ten without refitting; refitted on all of them it returns the same tables. N14 ends 佳, the day code for the 9th, the date on its form. Two telegrams from volume 4 (V4B, V4D) were never used to find the key and decode with it unchanged. The names that come out belong to people holding the right offices in June 1916: Zhang Guogan, Gu Zhongxiu, Tang Xiangming, Tang Hualong. Every digit was re-read blind on the scans by Brice Dudout, without seeing the decipherment, except that only 4 of the 22 sheets of V4B have been re-read so far.
The check made here (20 October 2026). His verify.py reproduces the published raw texts from his digits and scores the 容密 text at 3.18 against 200 random keys of the same form (best −1.67) and 200 shufflings of the digits (best −1.46). His search_rongmi.py, rerun from scratch, finds the hundreds and tens tables exactly and the units up to one carry, but not the 90-for-00 rule; he describes that last step as made by hand. A decoder written here from the key statement alone, using the Unihan telegraph-code table already in this repository, gives the same character as his published text for all 1,306 groups (five groups carry an illegible digit). This confirms that the key as stated turns his digits into his text; it does not re-read the scans.
04 What they say
Hsueh Chun-tu’s edition of Huang Xing’s 1916 drafts has nothing between the pieces of 8 and 20 June, and these telegrams are mostly dated in between. Translations below are Dudout’s, shortened.
Arms and loans
On 9 June Huang Xing wires Governor Lü Gongwang of Zhejiang, through Shanghai (N14):
轉呂都督鑒:袁死,大局益艱,非切實預備,不足以申張國法、奠定國基。感佩藎籌,當効棉力。械先運,款百萬亦可卽成。興佳
“Yuan is dead and the situation is harder; without real preparation we cannot uphold the law of the State. The arms will be shipped first; the loan of one million can also be concluded at once. Xing, the 9th.” Zhang Xiaozhun’s telegrams give the order: about ten thousand rifles, ten or so mountain guns, machine guns (N02, N12), with a Japanese intermediary willing to lend a million for the purchase. Lü asks for exact models and rounds per weapon (N21), offers Zhejiang’s tobacco taxes as security (N25), and promises payment before 30 June (N36).
Law and armed force
On 11 June (N19b) Huang Xing answers a proposal from Shanghai to restore the old Constitution and Parliament and form a new cabinet: he warns that “a legal solution, without sufficient armed force behind it, will have no effect”, and asks that Zhejiang be the pillar of the South-East. From Shanghai, Yin Ruli, Ge Jing’en and Huang Fu report the meeting at Tang’s house: Tang Shaoyi and Tang Hualong will not go to Beijing until Yuan’s laws are annulled and the 1912 Constitution is restored (N24). In late June (V4B) the Shanghai group reports that Duan Qirui is back to the plan of three delegates per province.
05 What is open
- 48 characters are kept as decoded but not understood (〔x〕), mostly in N36 and V4B, and 6 groups (N12, N21, V4B) have an illegible digit. 55 more are probable readings, shown in braces in
reading.md. Most come from uncertain digits on the police copies (the clerk’s 一, 二 and 三 are hard to tell apart). A few codes recur with an unexpected character (繒 for 生, 盻 for 盼); they are marked, not corrected. - V4B, 265 groups over 22 sheets, has been re-read blind on only 4 sheets. In V4B and V4D the digit file includes framing repairs (a digit missing or extra) inferred from the decoding, still to be checked on the scans.
- In an earlier reading made here under the old combined page, one group in N24 (2530, kept as 〔滠〕 in Dudout’s edition) was taken as 2520, 灰, “the 10th”, on the sense alone (“on the 10th a meeting at Tang’s house”, after “the 9th” in the same sentence). The edition and the text here keep 〔滠〕.
- No copy of the 容密 book has been found, and the 1916 edition of the telegraph code is not identified. The texts have not been found in the 黃興集 or in Li Yuanhong’s correspondence, which are still to be searched. The translations are proposals.

Identifications of people are candidates; uncertain passages are marked as on the site. ## N11 — 8 June 1916 To be passed to Mr Suchu: telegram received. Your view is indeed the key point; I would like to return to Shanghai at once to hear your advice, but the business in my hands is not settled and I cannot get away for now. If you wish to advise me, please send secret telegrams at any time; whatever is in my power I will do with all my strength. — Xiaozhun. The 8th. Note: 溯初 = Huang Qun. Digits re-read by Brice Dudout. ## N12 — 8 June 1916 Also to be passed to Governor Lü: rifles, eight […]; machine guns, six […]: ready for shipment. The intermediary Yoshikawa is willing to lend one million to buy arms, to be repaid later out of that sum. Which security is best? Please choose two and wire details, so that I can pick one and negotiate. Pledging the wine monopoly for a small loan of one million does not seem worthwhile. Reply soon. — Xiaozhun. The 8th. Note: Digits re-read by Brice Dudout. ## N14 — 9 June 1916 To be passed to Governor Lü: Yuan is dead and the general situation is harder. Without serious preparation we cannot uphold the law of the State and lay its foundations. Grateful for your devoted plans, I shall give my modest strength. The arms will be shipped first; the one-million loan can also be concluded at once. — Xing. The 9th. Note: Digits re-read by Brice Dudout. ## N19b — 11 June 1916 Your telegrams of the 8th and 9th received. You advocate restoring the old Provisional Constitution and Parliament and forming a new cabinet: far-sighted. If it can be done, the other questions will solve themselves. I have wired our friends Yuan and Feng to gather everyone’s agreement in Shanghai and publish my view, so that we speak with one voice. But a legal solution will have no effect without sufficient armed force behind it. I still hope Zhejiang will press ahead and be the pillar of the South-East, and at the same time wire Ganqing and Xiahuang separately to march quickly on Hubei and Jiangxi: only then can we hope for peace. Here I have reached an understanding with the authorities: no loan to the Northern government before North and South are unified. For information. — Xing. The 11th. Note: 垣 = Li Shucheng, 鳳 = Chen Jiahui, 幹卿 = Lu Rongting, 俠黃 = Li Liejun (identifications from the 黃興等電稿 edition). Digits re-read by Brice Dudout. ## N21 — 13 June 1916 […] Text of the telegram to be passed on: To Mr Zhang Runnong: the rifles, mountain guns and machine guns for Zhejiang — of what model exactly, and how many of each? How many shells per gun, cartridges per rifle and per machine gun? Are the leather equipment, gun accessories and pack gear all complete? Earlier telegrams did not give types and quantities, and the arrangements changed often, the numbers with them. Please wire full and exact details at once. — Lü Gongwang, the 12th. For information. — Li, Fu, En. The 13th. Note: 張潤農 = Zhang Xiaozhun himself; 驪郛恩 = Yin Ruli, Huang Fu, Ge Jing’en. Digits re-read by Brice Dudout. ## N28 — 14 June 1916 To be passed to our friend Baili: your telegram was unclear. I have already wired Yongyi to raise three hundred for you. — Zhun. Note: Digits re-read by Brice Dudout. ## N36 — 16 June 1916 To Mr Huang Keqiang and Mr Zhang Runnong: Mr Wu Zhaolian […] the arms from Japan […] to be shipped quickly […] funds […]. The price will be paid by Zhejiang before 30 June of this year, without fail. We hope it moves quickly. — Gongwang. The 16th. Note: Digits re-read by Brice Dudout. ## V4B — 25 June 1916 ? To Mr Huang Keqiang and brother Zhang Runnong: on the Zhejiang arms, according to Aoki, there is still hope of saving the deal; please do your utmost. On the Constitution, [Li] wanted to promulgate it directly by decree; Duan, though not utterly opposed, swayed by the legal advisers of the monarchist party and wishing to avoid [the charge of] arbitrariness, insists that some procedure be followed before restoration — hence the idea of three delegates per province, then of three chosen by each province from its parliamentarians. Tang Jiwu (Tang Hualong) then found a compromise: Duan would ask the parliamentarians in Shanghai, in a personal capacity, whether to restore the old Constitution; all would sign, not in the name of the parliamentary group, a reply calling for restoration, to be presented to Li for promulgation. Ding Shiyi and Xiao Jinrong would first come to Shanghai to smooth the way, then Duan would cable his question. On the 7th Ding and Xiao arrived and reported to the parliamentarians’ meeting; the majority agreed, and Ding and Xiao cabled Duan to proceed. But after they left Beijing, Tang Jiwu and Ge Zhanhou (Ge Jing’en) cabled that the agreement on the Constitution had been overturned again: Duan again insists on three delegates per province and refuses. What the truth is cannot be foreseen; we will find out and report further. […] Note: Digits re-read by Brice Dudout on only 4 of 22 sheets (first and last). ## N02 — June 1916 (day not read) To be passed to Governor Lü: rifles, about ten thousand; mountain guns, one may hope for ten or more; machine guns being arranged […]. Funds needed within 500,000. The Zhejiang loan has no lead yet and will take long. The Zhaoqing loan of five million will soon be concluded; the authorities intend first to set aside from these five million the payment for the purchase, then […] ship. Please wire the Military Affairs Council at once to consult, and reply. Please post the regulations of the wine monopoly. — Xiaozhun. Note: Signature 孝準 = Zhang Xiaozhun (courtesy name 潤農), in Tokyo with Huang Xing; 呂 = Lü Gongwang, Zhejiang governor. Digits re-read by Brice Dudout. ## N08 — June 1916 (day not read) Telegram received. The funds for buying arms have been discussed several times; deferred delivery can probably be arranged. To keep it secret, there will be no inspection here. The quantity of ammunition has been negotiated several times; they say it can be done afterwards. The loan is being speeded up. — Zhun. Note: Digits re-read by Brice Dudout. ## N19a — June 1916 (day not read) To be passed to our friend Baili: we cannot hurry; I hope Mr Guan will come to Japan to discuss. Reply by wire. — Zhun. Note: 百里 = Jiang Fangzhen. Digits re-read by Brice Dudout. ## N24 — June 1916 (day not read) To be passed to Mr Huang Keqiang: on the 9th President Li wired asking the eminent men of Shanghai to come to Beijing and help. On the […] a meeting was held at Tang’s house. It was first proposed to ask four men, Jiwu, Jiufeng, Puquan and Jingsheng, to go to Beijing in their personal capacity and take charge, their position being that of the telegram of the 9th. After much study it was decided that Tang and Tang would first wire, saying in substance: “We are deeply grateful, but unless an order abolishes the traitor Yuan’s illegitimate laws and restores the Provisional Constitution of the first year, we will not come to Beijing for now.” Today Zhang Guogan wired Liang from Beijing that the return to the old Constitution has Zhi’s approval; […]; we hope for quick contact. Once the telegram arrives it can be announced. […], sent by the head of State to Nanjing, can explain everything in person. Let the independent southern provinces issue a circular telegram and seek unification at once: the chance must not be lost. The ban on cipher telegrams has been lifted. For your information, etc. Tang has decided to leave for Beijing tonight. For information. We often see our two friends Yuan and Feng. — Yin Ruli, Ge Jing’en, Huang Fu. […] Note: 濟武 = Tang Hualong, 九峯 = Gu Zhongxiu, 溥泉 = Zhang Ji, 靜生 = Fan Yuanlian, Zhang Guogan = presidential secretary-general; 芝 = Duan Qirui (candidate). Digits re-read by Brice Dudout. ## N25 — June 1916 (day not read) We have just received from Governor Lü a telegram saying: the tobacco tax yields about 280,000 a year; the tobacco and wine licence taxes bring the treasury more than 140,000 a year; these two items could serve as security. The wine tax, about 900,000 a year, does not seem suitable; please settle with the other party. The items above […] apart from the wine monopoly; we state this expressly and await a reply, etc. For information. Also, the Zhejiang governor has sent Mr Wu Zhaolian to Japan to meet you; please advise him on everything when he arrives. — Li, Fu, En. […] Note: Digits re-read by Brice Dudout. ## V4D — June 1916 (day not read) As to the arms, Aoki and Takakura have both promised to do their best; negotiating again with the General Staff, there may still be hope. Please ask Mr Wu to stay for now. [Yin] Ruli left for Beijing last night with Zhang, Fan, Wang […] and Xiaoyuan […]; [Huang] Fu is not yet back. Business here is handled by Hao. For your information. […] Note: Digits re-read by Brice Dudout.
