autokey (version 1.4, 20 March 2001) | index ../autokey.py |
autokey.py - basic vigenere-based autokey cipher for python.
Requires cipher.py by Tesla Coil <tescoil@irtc.net>
and (currently) ecipher.py by me.
Auto-key ciphers need a basic key to provide a useful period;
the rest of the message is usually enciphered by starting again
from the beginning of the plaintext.
This approach can be extended for other polyalphabetic ciphers
like beaufort, and variant beaufort.
TODO: get gronsfeld working with alphabetical key.
