This is my first crackme written in C++..

Its not too difficult, but theres a couple of simple tricks and hard to follow commands I think, so ive given a rating of 2.

You should *keygen* this app, I think a patch would be far too easy here!

Difficulty: 2 - Needs a little brain (or luck)

indeed, this is how I can learn to improve my code...

Ive now written its big brother, 'c++ crackme 2' which wont allow for self keygenning, or at least I hope, so now you *should* have to understand the full keygen routine :)

an excellent example, NoRG, of attacking a programs weak spots :)
