(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: '227271244 15305sw3340337252237340U'decoded message: 'the holy grail'
