问题 I can't seem to get password_verify to work w/in my php PDO code. My pass field is stored as varchar(255). I've been reading similar questions, but from what I can tell I have it set up right.

问题 I'm making an application in PHP and there is a requirement that it must be possible to decrypt the passwords in order to avoid problems in the future with switching user database to different system.
