Joomla 1.5 password hash Class 1.0 for QT using C++

[RajabNatshah]

Hi All QT Developers

This is a Class I mad for some Projects.
I need it Under the Development work in some point.

I wanted to shear it with you all
to make use of it in your applications which you may need to
have access to Joomla Database and Connect it using QT Library.
using C++.. to work at Windows,Linux, Unix, MAC or Mobiles as will..


For Example if you have database connected to Joomla 1.5
and has got the database structure,
But in your application you need to pass the username and password
and you need this tool to decrypt the password users type in your applications

This Class will help you decrypt the password or Create a new password for Joomla.
if you want your application to add new users to Joomla. so the user will be able to login
to the site even if they registered using your application.

As the Application can be downloaded and installed. but in some point we need to verify that user is in our Joomla database or not and the password is correct or not..

I hope you can use it in your projects.
and any help I'm available.

I have attached the files so you can use them directly in your Development under QT Library
