Description
find the message that appears when entered correctly
jeffli6789 on 6:53 AM 12/12/2020: I am very doubtful that this is solvable unless we brute-force the sha256 or DES, any hint on it?
Xor0 on 3:48 AM 12/27/2020: The DES function is implemented to fail on purpose and default to the hard coded sha256 hash. That turns this crackme into a sha256 brute force challenge. The hash didn't turn up on any of the lookup pages I found.

redkage on 8:28 AM 05/03/2021: Same.
We need to find sha256(x) = "2194db1ff7426b1b773c498155af1d15c713ea25eaf89285d9c889cfe3b5fde4"
Though... there is a lot of dead code. The GetComparedTime() crashes on purpose. The msgbox to show the flag also kinda recurse GetComparedTime()
The GetCurrentTime() is the opposite it never crashes though there is some hex returned when it catches.
I dunno Rick... is this challenge fake? Maybe these dead code are hints to help us find the sha256 input.
Tut on 10:13 PM 05/17/2021: i could find the string when entering correct, it is cracked.. congrats
but it seems like i cant find it in the debugger. this crack me seems very hard.

DeadShot on 8:28 PM 05/27/2021: involves 0 reversing skills, only guessing and bruteforce, did not expected this type of timewaster
nn653 on 1:16 PM 09/16/2022: Deluxe is this possible to crack this without brute force?
devsoft on 12:49 PM 03/16/2023: Deluxe, can you type some hint, so I can make some Char exclusions on the bruteforce Algo? Thanks for all!
deluxe on 1:56 AM 04/02/2023: guys, that was a long time ago now i don't remember anything about this file...
