VB4 Auth on external pages?

[forcerm]

I'm using vb auth module for code igniter to try and auth vb on external pages, however i think it's outdated and generating hash incorrectly or something, this line has been thought to my attention?

PHP Code:

    function is_valid_cookie_user($userid, $password)
    {
        $sql = "
            SELECT username
            FROM {$this->dbprefix}user
            WHERE 
                userid = " . $this->db->escape($userid) . " and
                md5(concat(password,'".$this->license."')) = '$password'
        ";
...etc 


According to this it uses the licence which i believe is not true anyway, i've been told to use cookie_salt but dont know how to integrate it?

If I understand correctly a user lands on an external page and you want to check their cookie so see if they are logged into vbulletin. Is this correct?
