s3cana on 11:38 AM 07/02/2021: three check
first check 1-9
second check x & 1 = 0
third check strcmp(x,'R3KT')
ka0s on 2:43 AM 07/05/2021: Lots of people don't understand the last strncmp :).
Legacyy on 6:36 PM 07/05/2021: yeah haha, it's not the whole string ;)
MKesenheimer on 8:08 AM 07/15/2021: Cracked it :) Thank you!

uglych on 1:53 PM 07/28/2021: 4444-XXXX-RXX
last strncmp compares only first symbol so it could be RXX as well.

hack_the_moon on 5:31 PM 11/27/2021: nice one. people miss that it only compares 1 character in the last step, so for example this key is valid: 1234-8888-R000
th3h3d on 7:25 AM 12/03/2021: nice one!
knight on 11:06 AM 12/31/2021: Great one, Solved! :)
Onyx_Pl01t on 10:33 PM 01/04/2022: pretty nice CrackMe. i noticed that the check_three of your serial accepts character of length greater than 4
for example, 0123-2468-R1234567
for the case of your serial XXXX-XXXX-XXXX
i made a bruteforce python script that give a serial in the desired format and input it automatically in the program.

Wiktuur on 9:41 PM 06/25/2023: Quick work and I found the best sequence of 1234-0000-R***
* can be anything, even can be more than 3 characters
yep, that means
1234-0000-R works too
faisal098 on 11:25 PM 04/26/2024: nice challenge i would say it's not too easy
spoiler|

the first four digits is any number
the second four digits is an even number
the third four digits i think it was supposed to be "R3KT" but it only checks for the "R"
