See :mod:`passlib.handlers.mysql_41` for the new algorithm was put in place in version 4.1 This algorithm is known to be very insecure, and should only be used to verify existing password hashes. http://djangosnippets.org/snippets/1508/ MySQL 4.1.1 / NEW PASSWORD This implements Mysql new PASSWORD algorithm, introduced in version 4.1. This function is unsalted, and therefore not very secure against rainbow attacks. It should only be used when dealing with mysql passwords, for all other purposes, you should use a salted hash function.
