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"

Nice crackme! Posted detailed solution :)
darkcrow on 2019-03-21 12:29:
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!

Nice Crackme, Ghidra sometimes gives me a hard time decompiling tho.
Here are some keys:
|XVx"{]5F2
IaVm,|tK!2
n.Vm*}J6#2
~EV{!}DK,2
h4Vw*},\2
S1Vh |iFa2
L V|!{|:i2
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.

It's a nice one. Having a lot of fun solving it. I created a Python script which generates correct keys: https://pastebin.com/UQTtrsMz

[Click to reveal]The first crack me that I tried, really fun! I had trouble keeping all jumps in my head so I rewrote the jump parts in C.
One of many passwords: VVVz2zz222

DonKillha on 2020-11-20 15:51:
[Click to reveal]thank you for the opportunity of practice that u gave me , the password is HlVg3z8MS2 but there are multiple passwords, this is my first crack ever :D
R3tr0BS on 2020-12-02 15:35:
well, this was awesome, easy and for beginners, instead of finding the real password i just changed the je to jmp.
alessiosca on 2021-07-29 17:32:
instead of trying to find what the password(s) might be, just change the "je" to jmp. every key will be correct.

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 :(

Huh, I created a patch (with linux version of IDA Pro) for this crackme ;)

[Click to reveal]First crackme done! :)
One key that would work: gmVf3z8Ai2
Solution by rain on 2019-03-20 17:24: Description of how the crackme works and how to generate a valid password for it! Does not include keygen but it includes sample password!
Solution by darkcrow on 2019-03-21 22:59: How the program works, in a simple language to those who are new to reversing. Includes a table for better comprehension, and a sample password, for testing purposes.
Solution by Snowball on 2019-09-14 11:10: A PDF filled with pictures, instructions and links to other resources to get help. I hope it helps :)
No keygen included.

Solution by colbyjacobe on 2024-04-09 06:00: This solution includes a detailed analysis and explanation of the crackme along with a keygen executable and corresponding source code.
