and let me add that crypt(3) actually takes is 2 parameters, a key and a salt : crypt(key, salt) [take a look at the crypt manual na lang] the salt adds an additional randomness to it ( so that even two users with the same passwords will not have the same hash....unlike win nt and lm hashes) ..anyway, the point is, we can't recover the original password....WE CAN, however obtain a password whose hash is the same as the original. and that password is good enough. =) ramil -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
