Hi, this is my first KeygenMe : Bit It! As it's my first one, I may have missed some things. If you've any critics to do, do it : I'm open ! I want to know what's wrong if something is. (I'm usually doing .NET things, I just wanted to do a crackme in c++). Lang/Compiler : C++ / MinGW (eheh no IDA sigs) Crypto? : No hardcore crypto, just a little easy algo + some checks Difficulty : Medium ? but it should be relaxing. I don't think you'll find this kind of serial check Expected: serial (fine) or keygen (great) [if you've done some work but didn't finish, notes of your research is fine to me too] Thank you for trying ! Bit it!.zip
