Solved, i agree with @BitFriends, maybe a lv 2 would be fair. By the way, nice challenge.
./ZED-Frequency.bin keyfile
the generated key is: 01234567890123456789012345
you succeed!!

Nice crackme @egg.
The choice of the serial charset impacts a lot in the keygen performance, btw, thank you. |

Solved, you should downgrade to lv 1. Thanks.
Hint: use cp command. |

Hello timotei, i cracked it. I read about Fravia, and he was a very smart reverser, btw, thanks for the crackme. |

Solved, a little tricky, it took me a while to know how to pass the password correctly.
The password is easy to retrieve, the hardest part is how to pass it correctly to the program. |

It isn't lv3, it's lv2, but nice crackme at all. |

Thank you for your sharing your opinion, i hope that you did enjoy, try to solve my second and third crackme. The 97 is just the ascii value of 'a', and my anti debug trick for this one were only ptrace and some code obfuscation, but the others have an anti-disassembly trick and the last one has a little surprise. |

You're welcome. If you have any other doubt, feel free to ask me.
Also it's header screwer and not head screwer kkk, my mistake above. |
2019-09-25 20:17 |
| Yet Another Keygenme/Crackme |
Yes, i corrupt it. I used a custom head screwer to do it, but when you understand how it works, it will be easy to patch it, in order to get a disassembly view. |

An awesome challenge, it was thought to solve ahah, thanks for the crackme, i will upload my solution soon.
Oh, before i forget, the code is a "Self-modifying code" or not?
If you can give a copy of the full source code in my email, it will be awesome.
Obs: my email will be in the solution. |

I solved it, in a lazy way, i need to look better for write a keygen for him |

Really easy, solved. I will post a write up.
Thanks for the crackme.

@dosisod, my code was doing the wrong stuff akkaka, i've noticed after some trial-error, that was a curious pattern in huge numbers kakak and i tried with positive integers, with my crap corrected, and nothing, so i decided to run against negative integers and voilá. One more question, why did you ignore the 0 seed? |

Nice crackme, at least lv 2, but definitely not lv 3.

@destructor, nice one, it took me some time, but it was a funny exercise. I think that i found the correct string and i will submit a write-up soon. Thnx. |

@dosisod, so for a sat solver: https://en.wikipedia.org/wiki/Boolean_satisfiability_problem
Yeah, i noticed that a simple bruteforce doesn't worked, but i will analyse the algorithm again, thnks. |
2019-07-26 17:54 |
| Paimon evokation |
if is that, i think that you could downgrade the lv to 1... |
2019-07-25 23:09 |
| Paimon evokation |
the solution is the coordinates? |
2019-07-25 23:05 |
| chainbreaker |
Hey @dosisod, does this crackme need a sat solver? Or does it have a solution? I tried and i figured out the algorithm, but i stuck after that. |
2019-07-25 01:17 |
| keygenme |
Done.
I will upload the solution soon. |

Nice and weird crackme, after a long debug session, i could achive the output:
Wow, you got it right !
Was it blind luck ? Was is your first try ?
Okay, bonus for you
If you like this story, it's a modified version of a light novel called "Lazy Dungeon Master"
There is a manga too apparently
I'll try my best to go sideway and write my own novel inspired from the original. I'm not a good writer and english isn't my main language
Ah... i don't want to work
PS : congralutation !
Thnx for the crackme.

Hey @kerk2x, is it the final output ?
I feel your pain, you went this far and failed this check. Now you have to do it all over again
I'm pretty sure it's a major pain. I know i wouldn't want to do it since the chapter is finished anyway
Feel free to skip it.
But you'll miss the bonus prologue and congratulation.

@ker2x, i think that i solved this crackeme, if the final output is something like that:
BWAHAHAHAHA BAKAAAAAAAA !!! 0x5dd614a4 is super totally wrooong !
Segmentation fault (core dumped)
...
ho damn, that's right...
WHY ?
To be continued... (you really succeded but i'll kill you anyway. don't worry, you'll be fine)
Falha de segmentação (imagem do núcleo gravada) (same as segmentation fault, because i'm brazilian xD)
