Description

Goal: Reverse engineer the key validation algorithm and either find a valid key manually or write a keygen. Patching the binary will not reveal the secret message — a valid key is required to decrypt it. Instructions: Run razkom_v1.exe, enter a key at the prompt when asked. A correct key will decrypt and display a hidden message. See HINT.txt for the key format. No installation required. Dependencies: None. Standalone Windows x64 executable. EDIT: Any valid key will be accepted, but only the original key will decrypt the secret message correctly. Patching or keygen alone won't get you there — you need to fully understand the algorithm.
