Xataface Forums

I need to use user authentication of joomla 1.5 table. But for check password I have to use a special algorithm (md5 + salt). Is a way to do this?
Is possible to write my check password function?

You can implement the xxx__serialize() method in the delegate class to make this possible. All values are serialized before being inserted or compared in the database and this method overrides how that serialization takes place.

e.g. if the column name is 'password', the the users table delegate class would contain a method like:

Code: Select all

function password__serialize($value){
    return my_special_encryption($value);
}


Note that if you were only using MD5 (and not the combination as you describe, this could have been accomplished with the 'encryption' property in the fields.ini file.

In fact, If you wouldn't mind posting your solution for your serialize function I can add this to the next release of xataface as the 'joomla' encryption so that it will also be able to be achieved via the encryption parameter. Currently only MD5, PASSWORD, SHA1, and ENCRYPT are supported.

It works....but I'm not sure if it is correct....

Code: Select all

function password__serialize($password){

   $app =& Dataface_Application::getInstance();
   $query = "SELECT id, gid, block, password, usertype FROM jos_users where username='".$_POST['UserName']."'";
    $risultato = mysql_query($query,$app->db()) or die("Query fallita: " . mysql_error() );

   $linea = mysql_fetch_array($risultato, MYSQL_ASSOC);
    /* Liberazione delle risorse del risultato */
    mysql_free_result($risultato);

   $arraypass=explode(":", $linea['password']);
   $salt=$arraypass[1];
   
   $ret = md5(trim($password).$salt).":".$salt;
   return $ret;
}
   

Well, this is doing a bit of extra stuff that it doesn't need to do. The __serialize method receives the password as a parameter, which you are meant to encode:

Code: Select all

function password__serialize($password){

   $arraypass=explode(":",$password);
   $salt=$arraypass[1];
   
   $ret = md5(trim($password).$salt).":".$salt;
   return $ret;
}


Hi, The salt is calculated on registration by an randomic algorithm on create password, so to get md5(pwd.salt) I have to read it from database.
