  1. Extract target hashs from the binary
  2. Bruteforce the flag

A tip for reversing c++ binary is to ignore anything you don't understand to preserve sanity. The binary read the input for a file, apply ROT13 to it, and compare the hash of each byte. The hash function is base64 . md5hex . md5hex To recover the flag, just bruteforce it.
