Aether on 2020-11-17 12:47: I'm a beginner, I spent ~1,2 hours on this challenge and I really liked it !

jeffli6789 on 2020-11-19 13:18: interesting one. Though I think r13 needs to be zeroed on entry

trizas on 2020-11-24 12:46: N1c3 :)

trizas on 2020-11-24 12:46: you dont need to patch it, only understand the algorithm

BitFriends on 2020-12-03 19:45: Cool challenge! I wrote a keygen! Take a look: https://pastebin.com/givqQMHe

RobertoSpartan on 2021-01-01 14:36: This was a nice one. Took 45 minute to decipher the algorithm, 30 minutes to find out that there is no single solution. Still don't know why exit must be in a subroutine.

SirWardrake on 2024-05-10 00:11: Good job, very nice one. Valid key (there are many valid keys): 222p22=p222p22=p

pale_delirium on 2025-11-09 04:32: Just solved it. I really enjoyed this one. No miles of C++ GTK code to sift through, just pure ASM goodness. As an older beginner it took me just longer than 2 hours.
