Description: 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.

Nice work. I like that you "wrote" the logic in C instead of patching the binary. Very nice.
lazy_h,
Thank You, for taking the time to produce and edit this video. Very helpful, I've always wanted to take the time and crack Mirc, just never had the time to sit down and do it. I usually press the continue button.
