joomla password encryption

Question

I need to access the joomla user table jos_users for login checking from external php script [codeignitor].

joomla storing password like this

Answer 1

From the joomla source file libraries/joomla/crypt/password/simple.php there are multiple ways they get stored, and some do not have a ':' character.

    switch ($type)
    {
        case '$2a$':
        case JCryptPassword::BLOWFISH:
            if (JCrypt::hasStrongPasswordSupport())
            {
                $type = '$2y$';
            }
            else
            {
                $type = '$2a$';
            }

            $salt = $type . str_pad($this->cost, 2, '0', STR_PAD_LEFT) . '$' . $this->getSalt(22);

            return crypt($password, $salt);

        case JCryptPassword::MD5:
            $salt = $this->getSalt(12);

            $salt = '$1$' . $salt;

            return crypt($password, $salt);

        case JCryptPassword::JOOMLA:
            $salt = $this->getSalt(32);

            return md5($password . $salt) . ':' . $salt;


    }
}

Answer 2

Joomla "understands" the passwords with "normal" md5.

What I've done in the past (to test a user's login), was to save the original password, encrypt a new one in md5, replace it in the database, test it with the browser (and it works) and when I was done, paste the original password in the database.

If you just use md5($password); it'll work, try it. Joomla has a mechanism and it can work with multiple types of passwords (including, as of late, strong passwords). You don't have to worry about the part after the colon. Just use md5($password) and it'll definitely work.

By the way, this'll also work on Joomla 3.x.
