krcenov on 4:47 PM 03/20/2019: Really fun!
I made a keygen for this, check out the solutions.
Anyway this was real nice, a little hint:"There are a lot more than 1 passwords"
rain on 5:25 PM 03/20/2019: Nice crackme! Posted detailed solution :)
darkcrow on 12:29 PM 03/21/2019: Great crackme! I am a beginner in reversing, and it was very simple to find a password. My next step is to write a keygen to this. One more time, congrats for the challenge!

Here are some keys:

~EV{!}DK,2
h4Vw*},\2
S1Vh |iFa2

wPV~0~P=92
y2V})|l=e2
m(Vm"~y (2
I also made a keyGen: https://pastebin.com/nXJiE2qN
I would also appreciate if someone knows a cleaner way to code something like this.

R3tr0BS on 3:35 PM 12/02/2020: well, this was awesome, easy and for beginners, instead of finding the real password i just changed the je to jmp.
alessiosca on 5:32 PM 07/29/2021: instead of trying to find what the password(s) might be, just change the "je" to jmp. every key will be correct.
TrollZik on 5:02 PM 11/26/2021: I found ZaVz0z9Aa2
coquee_ on 9:38 PM 12/15/2022: Damn, I feels so bad, this is not my first frogram, and I saw people that in the 1st program get the keys, this is my 12th program, and I only patch them, no clue how to get keys :(
