vigenere.py - vigenere/beaufort/variant beaufort for python.
 
Implements the vignere/beaufort/variant beaufort classical ciphers.
Requires cipher.py by Tesla Coil <tescoil@irtc.net>
and (currently) ecipher.py by me.
 
Since the three ciphers are so similar, you get three for
the price of one :)
 
How to encipher/decipher:
 
Beaufort:
    enciphers/deciphers inversely.
Vigenere:
    deciphers via variant beaufort encipherment with the same
    key.
Variant beaufort:
    deciphers via vigenere encipherment with the same
    key.
