Enigma for Sale

Don't tell Dave! It's an attractive item to enthusiasts of early science, mathematics, history and computing instruments.  "If the receiving Enigma was attuned to the same settings -- one of a possible 158 million million million combinations -- the encrypted message would then be automatically decoded."


  1. Hi all,
    If you are unable to pick this exquisite device up at the Christies auction, there is a fine Enigma simulator online at the following site:

    If you and a correspondent by Email would like to encrypt and decrypt your messages using this device, simply agree on a list of indicators so that both ends have their wheel settings the same, and you may then exchange encrypted traffic.

    As long as the initial settings are not compromised, no casual interceptor will read your traffic.

    There are of course certain organizations who may have better luck.

    bet you can;t read this you dummy

  5. Hi all,

    Without the initial wheel settings, decoding the cipher is very difficult.

  6. Come now. My code is VERY easy to crack! Even dummies--you know, BACKWARD people--can break it.

  7. Hi Lanny,

    Your comment is written in a variant of the Caesar Cipher, in the words of Suetonius:

    "If he had anything confidential to say, he wrote it in cipher, that is, by so changing the order of the letters of the alphabet, that not a word could be made out. If anyone wishes to decipher these, and get at their meaning, he must substitute the fourth letter of the alphabet, namely D, for A, and so with the others."

    —Suetonius, Life of Julius Caesar 56

    In your case of course, you have slid the cipher alphabet so as to align Z with A, Y with B and so forth.

    Thus a partial decrypt:

    I just read the security meeting information forward initiative. Maybe if our traffic.....Etc.

  8. Very good, Dave! I didn't know about the illustrious background to my code.
