No can do. I mean, you can't do something like that. You can either give
(actually, revoke) that particular user/role permisions to read the
table with the passwords, or you could store hashed values to the
database.
Later is prefered, I'd say. You could use md5() function to create
hashes, store those in the database, and when checking for the
credentials compare the hases. You'd compare user input flushed trough
md5() function with the hash you have in the database. That way you
don't know what user passwords are, and you could only set a new
password if user forgets his/hers password.
You don't need encrypted passwords.
