[PHP-DB] Unix crypt
Hi all, Do you know if the php "crypt" function really works like the unix one ?? I mean, when I compare my password on my system (crypted with unix crypt) and my password crypted with php crypt, it's not the same. And the php crypt doesn't send twice the same answer.

Re: [PHP-DB] Unix crypt
Salt is the first two characters in a DES-encrypted password. It is used as a modifier to regularly-encrypted passwords to avoid the same encryptions for similar passwords. You must extract the salt first for your reference password, then use it as a salt to encrypt the password you want compared.

Because if you don't specify the salt, this will be randomly selected each time you call the function, so it will give different results each time. As for the system password, keep in mind that different systems use different crypting algorithms; I guess that the right thing to do is carefully reading of both php's crypt manpage that the system's one.
