I know. I've being thinking about how to do it, currently it involves having N hashs where you generate them like: echo -n "password" | md5sum 5f4dcc3b5aa765d61d8327deb882cf99 - echo -n "assword" | md5sum 297dbe7699dcfa60609bf9e667e2e4dc - echo -n "pssword" | md5sum 537319a7934aea9825d1af85df588fde - echo -n "pasword" | md5sum 22e5ab5743ea52caf34abcc02c0f161d - echo -n "pasword" | md5sum 22e5ab5743ea52caf34abcc02c0f161d - ect, then check the submitted password by testing it against these hashes by removing characters in the same fashion. Just as an early idea. I think it's a good idea, what if you could encourage users to use stronger passwords by telling them that "the system will forgive near misses, so don't be afraid"?
