This plugin seamlessly changes your stored password hash to a far stronger one. The hash that it is changed to is 
generated with a variety of variations on PBKDF2, including my own ARC4PBKDF2 which adds custom ARC4 encryption 
during the hashing processs, then a SHA-1 to meet size constraints. This plugin exponentially increases the strength 
of your stored password.
