DosX on 2024-04-08 09:35: Damn. The site cuts the heart symbol consisting of a less than sign. I wanted to write "Developed with Love by DosX" but something went wrong. In any case, good luck in solving this crackme.

pavler on 2024-04-08 12:34: good crackme, and patch guard also funny

nightxyz on 2024-04-09 01:54: Solved. -----Spoiler------ Starts with "x" character. -----Spoiler------

nayani on 2024-04-09 14:41: Guys, can anyone give me a little nudge. it's a little confusing.

Mew_ on 2024-04-10 18:25: This was fun! Thanks :)

Satharus on 2024-04-13 23:40: Nice challenge, thanks :)

cnathansmith on 2024-04-14 09:32: @DosX the site just strips potential HTML tags from comments in the clumsiest way possible.

nopx64 on 2024-04-14 14:12: i made it display "[+] Correct password. You did it! :)" but i did not understand what it did, is it considered as cracking?

cnathansmith on 2024-04-15 00:37: @nopx64 the strlen and individual chars of the password are compared against constants generated through convoluted ways. You need to break on those comparisons and see what the correct values are for each.

nightxyz on 2024-04-15 07:04: @nopx64 You've probably either made a runtime debugging or made a patch to get that message. Patching is not allowed unless otherwise specified, You need to find the real password.

MugoSquero on 2024-04-20 23:56: I really enjoyed it. Analyzing both statically and dynamically in parallel helped a lot.

SirWardrake on 2024-04-22 00:49: Very nice crackme. Lots of unnecessary code that helps disguise the password. Well done

dredge on 2024-07-30 15:57: not bad.

Relatively straightforward walkthrough that requires extracting a lot of constants
