    MD5 has its weaknesses (see Wikipedia), so there are some projects, which try to precompute Hashes. Wikipedia does also hint at some of these projects. One I know of (and respect) is ophrack. You can not tell the user their own password, but you might be able to tell them a password that works. But i think: Just mail thrm a new password in case they forgot.
