Summary: My first keygen; Win32 GUI crackme with Name + Key validation. Used CFF Explorer for static analysis and x64dbg for dynamic analysis to trace the key validation algorithm. The program processes the name input through a semi-complex encoding function that uses different mixing operations for even/odd characters, involving ROL operations, XOR, and addition with constants. Reversed the algorithm and implemented a Python keygen that generates valid keys for any given name.
