Challenge of Reverse Engineering

I've written this one long time ago, just found it in my archive. Worth to give a try! BTW NO BRUTE FORCE! Keygenme.zip

VProtect is a new Protector by cooolie. This is the unpackme for you to test. />http://fs.unpack.cn/?fs=0&u=80 test_VP If you are interested, here is the download address of DEMO version. http://www.vmprotect.net'>/>http://www.vmprotect.net/demo/VProtectDemo.rar'>/>http://www.vmprotect.net/demo/VProtectDemo.rar And here is the official website />http://www.vmprotect.net

Well, it's been a while since I've been in the crackmes.de scene, so I decided to come back with yet another crackme. This one is just a tad bit harder (besides, everyone loves games). I decided not to enable any outsourced protections (obfuscation, etc...) because I want people to focus on the encryption routines and learn what to look for.
