Reversing DirectX & Blowfish
This tutorial has been on the boil for quite a while. I got close to nailing the problem late last month, but didn't end up finding the time to finish it until this weekend. This tutorial is a solution to another Crackme, but this time it's really not for the faint-hearted. Information on reversing fullscreen DirectX (Direct3D) applications and playing around with Blowfish can be found in this tutorial, and it's a bit of a mind-job - it also weighs in at nearly 40 pages (with some nice pictures thrown in)!
The crackme, by Silver, can be found here, and the solution can be found here on my site (or on Crackmes.de when approved).
I'd love to hear your thoughts
