I don't mean to disrespect Paul Rubin, but p3.py comes up in every discussion
of cryptography in python on this list and, AFAICT, has yet to come under
significant cryptanalytic scrutiny. That doesn't make it a bad example in this
case, but I would caution the OP that it probably doesn't make it a good
candidate for your encryption needs.
