This is my first KeygenMe
Serial must be resolved against name
Md5 is used
Its not packed
Coded in radasm
If the algorithm is solved, then its easy write a keygen.
You need to concentrate to solve the algorithm.
If you dont understand ASM,then you wont find the serial number.

Difficulty: 2 - Needs a little brain (or luck)
Platform: Windows
Language: Assembler

Funny crackme. However, you should've disguised your check more, since it can be solved pretty fast by detecting known patterns :)

I liked this one. It was fun! =D Short theory on what is happening: A MD5 hash (with modified constants?) is used on the username (+"TccT"). The entered serial has to contain every 3rd WORD in the hash. The numbers from the entered serial are combined with the MD5 hash and summed up. This sum must equal the original hash sum to get a good_boy.

Let me know if I'm right, s3rh47! XD


P.S: I'm working on a keygen now.

I have a lot of work to do, that is why I didn't have the time to write a solution and I see that qpt^J has already written one.

However he didn't exploit the fact that there are 17.592.186.044.416 different possible serials for one given name. That is why I will try soon to post another little solution.
