pranav on 10:53 AM 05/01/2021: That was kinda easier than 2.5, made a Keygen that lists out all possible keys.. Here is all valid keys for the crackme https://drive.google.com/file/d/1dNCX4QpN8b0B-NC1sqy5zD0Q0n5mY89a/view?usp=sharing

TrojanPoem on 11:27 AM 05/01/2021: I agree with you. However, I listed it for a higher difficulty as I was looking for mainly brute force solutions that utilize the crackme itself using e.g. a DLL or creating remote thread in the process to accomplish that.

featherfx on 2:28 AM 03/22/2023: the jumbled letters is a caeser cipher shifted 3 places to the left if you want to reveal the messages without cracking. If you want to crack it any 4 combo of characters that adds up to 19F in hex from their ascii will do it.
