Challenge of Reverse Engineering

Hello. This crackme is a bit of a challenge and may be the first crackme I have actually put some effort to. Half of this crackme is based on a library that I have coded and for wich I will provide the source code if the crackme is solved. Thanks. If the crackme crashes on some given keys - dont bitch this could be fixed but honestly I don't see a reason to. Writte a keygen and state a few words about the challenge. Greetings, xSRTsect.

Level: Just right to keep you entertained Solution: A keygen and maybe a tutorial to share your knowledge with othersEnjoy & Good Luck kgm18.7z
