The rotor Module

(Optional) The rotor module implements a simple encryption algorithm, shown in Example 2-42, which is based on the WWII Enigma engine.

Example 2-42. Using the rotor Module

File: rotor-example-1.py import rotor SECRET_KEY = "spam" MESSAGE = "the holy grail" r = rotor.newrotor(SECRET_KEY) encoded_message = r.encrypt(MESSAGE) decoded_message = r.decrypt(encoded_message) print "original:", repr(MESSAGE) print "encoded message:", repr(encoded_message) print "decoded message:", repr(decoded_message) original: 'the holy grail' encoded message: '22727124415305sw3340337252237340U' decoded message: 'the holy grail'
