Password Hash

[travisneids]

I've done my research but for the life of me, I can not replicate what vBulletin is doing! I'm creating a user from another website which duplicates what is needed in the vBulletin table but I still can't login with these users! Code follows:

PHP Code:

private function fetch_user_salt($length = 30) {
        $salt = '';
        for ($i = 0; $i < $length; $i++) {
            $salt .= chr(rand(33, 126));
        }
        return mysql_real_escape_string($salt);
    }
    
    public function vbPassword($clearPassword) {
        $object = new stdClass();
        $vb_salt = self::fetch_user_salt();
        $password_salted = md5(md5($clearPassword) . $vb_salt);
        $object->salt = $vb_salt;
        $object->password_salted = $password_salted;
        return $object;
    } 


My database saves the following:

PHP Code:

$object->salt INTO salt column
$object->password_salted INTO password column 


Am I missing a step? Another crazy ass MD5 or something? I feel like I should be able to login from the forums now.

Thank you!
