M1rage on 2:22 AM 09/16/2023: it says I'm using debugger when I'm not

thebovl on 12:18 PM 09/21/2023: No one tried to crack it?? ;(
jeffli6789 on 4:55 AM 09/22/2023: I had a look at it, and got a basic understanding of the algorithm, but I did not spend the time to actually solve it. This is a cool one, btw
cnathansmith on 7:44 AM 09/24/2023: @thebovl I accidentally tried a correct combo while I was working on it and realized what it was doing, which threw me off because I try to outline the write-ups as I go to help demonstrate the discovery process in a way that would help readers with other challenges and I wasn't sure how to work that in lol.
I'll try to take another look at it soon
dima_kettle on 7:59 AM 10/24/2023: Thank you for this crackme! Using of anti-debugging function is very cool! But I don't think, that is 4 level of difficulty, as verification algorithm is not so hard.
Anyway, thank you again for this nice crackme!)

After fixing this problem, the password-scrambling-part is easy to solve. Made a little keygen...
Nice one!!
