Antricks on 2019-07-05 07:52: I don't know if I got it right. After putting in the right (I suppose) key there's no "Good Key!" output, even though strings says there's a "Good Key!" string. Instead there's a second scanf. Is it programmed to output the "Good Key!" if the strcmp returns 0?

kawaii-flesh on 2019-07-05 16:54: Antricks, If you received a string of "Good key!" you're on the right track. And remember that crackme is not important!) P.S.: If you have any more questions, you can write to me kawaiiflesh@yandex.ru

SYS_V on 2019-07-06 06:14: as far as I can see, there is nothing in the crackme that shows how the files were encrypted. I tried XORing them together since they are the same number of bytes but the output looked like nonsense.

kawaii-flesh on 2019-07-06 16:08: SYS_V, For "xor" I used this program - https://my-files.ru/t4om5d And don't forget the hint in brackets)

kawaii-flesh on 2019-07-10 16:06: after correctly solved crackme should appear a new file(this is a continuation of the task)

juansacco on 2019-07-11 09:23: kawaii-flesh: Yes on my case I did got the file: CNP.7z. I have enjoyed your crackme, keep them coming!

SolitudeSF on 2019-08-05 22:02: there is no ...___ morse character. is it really correct?

markoto on 2019-09-11 14:21: This crackme can be a Level 2.

Shadorain on 2021-04-24 19:34: Yep the best hint is that you aren't done when u get "Good Key!" and read the file names literally and intently! Good luck out there!

What a fun crackme! Tricky one as well! Here is my solution in markdown, if you would rather a rendered version on a pretty site here is a link: https://shadorain.github.io/blog/Security/Reversing/Crackme_CNM. Thanks!

Tricky re, but not terribly complicated. Good exposure to pushing myself to use new features of Ghidra!
