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

In joomla standard you can create password using the following way

                     jimport('joomla.user.helper');
             $salt = JUserHelper::genRandomPassword(32);
             $crypt = JUserHelper::getCryptedPassword($password_choose, $salt);
             $password = $crypt.':'.$salt;

you mention that you are accessing from external file(or programs) then if you have joomla installation on other side you can access it from outside the joomla structure.

using joomla default frame work like this

define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );//this is when we are in the root
define( 'DS', DIRECTORY_SEPARATOR );

require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );

$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
