I don't believe this will work: you are forgetting about the salt, yes? I'm not sure about modern *nix's, but the salt *used* to be available in cleartext at the beginning of the "encrypted" password (SVR3.0e, YMMV)... J.A.

If your on about passwords from /etc/passwd etc. - you can't decrypt them, it's one way encryption... You have to take the password the user has given you, encrypt it - and them compare the result with the encrypted password on the system...
