How to write a keygen. This is a tutorial demonstrating the steps involved in writing a keygen for an application. The app (mIRC) is examined in a debugger (Ollydbg) and the keygen algorithm is reverse-engineered. From this, a standalone keygen application is created.

This tutorial is for educational purposes only.

  • Very very cool :)

  • For everyone who can't follow this tutorial because of the new method mIRC uses to register now, I have a solution for you! :D Go to "w w w [dot] oldversion [dot] c o m / mIRC [dot] h t m l" and download mIRC 6.0. Have a nice day everyone! P.S. Replace [dot] with a real one and remove the spaces.
