Crackme solution: CRACKME.58DD2D69 by zudas

I’ve finally managed to pull my act together and solve a crackme. It was a really simple one (its author rated it 1/10 on the difficulty scale), but I feel it was adequate to my skills. The purpose of this crackme was creating a general key generator, not modifying the executable to accept any key. I’m going to explain how I accomplished that. The only tool I’ve used was OllyDbg.

Warning: it will be all pretty basic stuff, so if you’re an experienced reverse engineer, you’ll be bored out of your mind.
