Very nice! :)

Attached is KG and uncommented source. But you must understand how this keygenme works - otherwise the source won't make any sense to you.

Hello.

I tried out this keygenme. So it is executing shellcode, which would display the good boy message.
The shellcode is decrypted with hard-coded key; some bytes are replaced with other bytes generated from the name/serial combo, a check is done

and finally executed. 

So it is possible to have certain name/serial combo to pass all the checks and yet segfault on running, as the generated shellcode is not proper.
