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;


    }
}
