Auth - DB_Crypt - any interest?

below is a Auth Container for doing Crypt rather than md5 - Its useful if you already have a database that uses crypt rather than md5's (i needed to work with midgard tables) eg. password field is either crypt($password) or "**$password" <- clear text.. any interest in fixing it up and adding? regards alan require_once(dirname(__FILE__)."/DB.php"); class Auth_Container_DB_Midgard extends Auth_Container_DB { function Auth_Container_DB_Midgard($dsn) {

       $this->Auth_Container_DB($dsn);
