The best way to do this as to use a one-way encryption and only store
the encrypted password. When the user enters the new password, encrypt
that in the same way and compare with the original encrypted password.
In this way, noone can get the original password even if they have
access to the encrypted version.

A good place to start the encryption is to use a CRC 32, combined with
some other methods. The source code for this should be available in
several places. Check the FAQ's of comp.lang.c++ and sci.crypt.
