Hello all, Here's my new keygenme. Hope you will like it Name: Levis's .NET Keygenme03 Language: vb.net Protection: I tried to obfuscate it manually, not base on any tools, or any techniques, just write code from my mind . But it takes a lot of time and don't know how good it is (maybe i'm so noob) Level: i think it's level 2 or 3 Require: Make a working keygen and then Please write a tutorial(if you prefer). Picture: A sample working serial: Name: Hello2013Serial: a93e63e9a06d969723a89fc695823284 Link download (or attached file): Enjoy and best regards, Levis Levis's .net keygenme03.exe.zip

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

Somewhere on your hard drive (obviously not going to say, the quest is with you) was generated, a file .ini containing the correct serial. If it is easier for you, find that file. large file, but is due to skin utilized. Good fun.
