  3. Jefferson disk - Wikipedia

    en.wikipedia.org/wiki/Jefferson_disk

    A disk cipher device of the Jefferson type from the 2nd quarter of the 19th century in the National Cryptologic Museum. The Jefferson disk, also called the Bazeries cylinder or wheel cypher, [1] was a cipher system commonly attributed to Thomas Jefferson that uses a set of wheels or disks, each with letters of the alphabet arranged around their edge in an order, which is different for each ...

    en.wikipedia.org/wiki/Zygalski_sheets

    A Zygalski sheet. The method of Zygalski sheets was a cryptologic technique used by the Polish Cipher Bureau before and during World War II, and during the war also by British cryptologists at Bletchley Park, to decrypt messages enciphered on German Enigma machines.

  5. Cipher disk - Wikipedia

    en.wikipedia.org/wiki/Cipher_disk

    The code can be a consistent monoalphabetic substitution for the entire cipher or the disks can be moved periodically throughout the cipher making it polyalphabetic. For a monoalphabetic use, the sender and the person receiving the messages would agree on a cipher key setting (e.g., the "G" in the regular alphabet would be positioned next to ...

  6. M-94 - Wikipedia

    en.wikipedia.org/wiki/M-94

    A wheel cipher being used to encode the phrase "ATTACK AT DAWN." One possible ciphertext is "CMWD SMXX KEIL." The principle upon which the M-94/CSP-488 is based was first invented by Thomas Jefferson in 1795 in his "wheel cypher" but did not become well known, and was independently invented by Etienne Bazeries a century later.

  7. Secret decoder ring - Wikipedia

    en.wikipedia.org/wiki/Secret_decoder_ring

    A secret decoder ring (or secret decoder) is a device that allows one to decode a simple substitution cipher—or to encrypt a message by working in the opposite direction. [ 1 ] As inexpensive toys, secret decoders have often been used as promotional items by retailers, as well as radio and television programs, from the 1930s through to the ...

  8. Music cipher - Wikipedia

    en.wikipedia.org/wiki/Music_cipher

    Music Cipher Wheel from anonymous 18th-century manuscript, Port-Lesney, France. Because Öttingen-Wallerstein's cipher uses relative scale degrees, rather than fixed note names, it is effectively a polyalphabetic cipher. The same enciphered message could be transposed to a different musical key––with different note names––and still ...
