January 7, 20169 yr 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.
