Description

Reverse the vm + shellcode and the math then write the keygen. Wrong input = maingless output Used encryption/cipher algorithms --> ROT13 + XOR + RC4 2 little hints: 1. The key used by stager shellcode is linked to a British rapper. 2. The username, PIN, and serial don't just transform independently; they mix with each other in 64-bit blocks. If you successfully reversed everything, you will see the correct output in "FLAG{}" format.
