Description

Nothing super crazy was used for the obfuscation, only stuff already known for years, might be fun if you want to learn about deobfuscation and anti debug techniques. It was made with my open source project called LeetObfuscator, you can find it on github. You can either patch it, make a keygen, or even bruteforce it, I left all the routes possible and everything is allowed, the only goal is to get the flag. Without obfuscation it's really nothing crazy, just some XTEA and a bit of convoluted code, maybe 2-3 difficulty at most, but the obfuscation really cranks the difficulty up (or so I hope). If you manage to beat it, leave a comment and say how you did it.
