  • Hacker News
  • What's the connection between this message and 2005? It was published then?
  • Is it possible that the key is incorrect but still decoded to a valid message? I realise it's possible when you're using keys that are the same length as the message, but I don't know exactly how the Enigma machine works and if this was something that they would do or not.
  • The correct title: Researcher brakes one specific stubborn historic enigma message with good help from Astra.

    Stubborn for a long time because the message used a completely different key from the rest of that day's traffic. Everyone assumed it shared the daily key. The original transcription had errors. The left rotor turned over at letter 72, which is rare and breaks standard crib attacks.

    What is cool, if true, is that it was a 2 day collab between the Leffer and Astra. To me this shows the importance of human in the loop, was still all also showing how immensely power of llm tools. But I think it’s getting a bit silly how much anrticles ignores the driving force (the person) in breakthroughs like this.

  • interesting, YouTube channel Veritasium just published a video on how Enigma was broken during WWII. at the very end they also give message that has yet to be decoded, although apparently they're different.

  • Neat, but "did it entirely on its own" is incongruous with "developing the necessary Python and C++ software for an Enigma simulator".

    I'd start by asking how much of that generated software is novel, or easily found on the web? Then, how much of the breaking process was offloaded to that software? If Astra is just handing off tasks to another computer, then I'm not sure how much credit it deserves. Finally, it looks like Astra provided some useful insights which narrowed down the search. Were these insights cribbed from elsewhere?

  • I think this is a bit late for the war effort.
  • gemini 3.8 flash in anrigravitiy oneshoted the descryption in about 45min non-steered run (opus is still running with the task, has some script to run for about 100min)

    Prompt

    Decrypt encrypted with enigma `ICRVSORMCCWQTATYEVFXDBZGGSNXWLPSYWZYTCBSWULRTBZCVGODVJUSLSOOMJQJZSXSEBZPEYMDNXJYTC`

    Result

    Raw Decryption (verbatim from the machine): BTTEUMANGABEDESMARSQWEGESXBEFINDEMIQINXROSENOWROSENOWXSOFORTFUNKANTWORTXWASCHBBSCH 2. Segmented German (with military telegraph conventions expanded): BTTE UM ANGABE DES MARSQWEGES . BEFINDE MIQ IN : ROSENOW ROSENOW . SOFORT FUNKANTWORT . WASCHBBSCH

    (Standard German radio conventions: X represents punctuation/spacing; Q was frequently substituted for CH to prevent transmission ambiguities; BTTE was an enciphering operator typo for BITTE; WASCHBBSCH was an operator typo for the signature WASCHBUSCH).

    3. Corrected German: „Bitte um Angabe des Marschweges. Befinde mich in Rosenow, Rosenow. Sofort Funkantwort. Waschbusch.“

    4. English Translation: "Please specify the route of march. I am in Rosenow, Rosenow. Immediate reply by radio. Waschbusch."

    Cryptographic Verification Re-encrypting the plaintext using the identical key settings reproduces the exact ciphertext byte-for-byte:

    Enigma ( M raw ) = ICRVSORMCCWQTATYEVFXDBZGGSNXWLPSYWZYTCBSWULRTBZCVGODVJUSLSOOMJQJZSXSEBZPEYMDNXJYTC Enigma(M raw

    )=ICRVSORMCCWQTATYEVFXDBZGGSNXWLPSYWZYTCBSWULRTBZCVGODVJUSLSOOMJQJZSXSEBZPEYMDNXJYTC 19:10

  • For anybody interested, the actual encrypted message:

      BTTE UM ANGABE DES MARSQWEGES X BEFINDE MIQ IN X ROSENOW ROSENOW X SOFORT FUNKANTWORT X WASCHBBSCH
    
    which, given misspellings, translates approximately to:

      Please specify the route of march. I am in Rosenow, Rosenow. Immediate reply by radio. Waschbusch.
