| CrackMe Hard 2 |
Great crackme!
I really enjoyed solving it. The VM layer was a nice surprise, and the custom validation/encryption logic made the challenge much more interesting than a typical keygen task. It took some time to fully understand the flow, but that made the final solution feel very satisfying.
Thanks for sharing it and for the effort you put into creating such a fun reversing challenge. Looking forward to your next crackme!
Cheers!
I ended up choosing the username "kek" during my analysis and managed to recover a valid activation code for it. Tracing the verification flow, understanding the VM instructions, and reconstructing the key generation process was probably my favorite part of the challenge

hitMan, i have to disappoint you, the key is valid if it outputs two inscriptions (already a little bit... , Good :)) |

Slava, message valid flag - Yes, you higher! GreeZW , you didn't show all the logic of the application, yours is unlikely to help in any way |

hashing is an irreversible process, what's the interest in examining your crackmy, it can only be solved by bruteforcing
Omg... |

I was wrong it is not keygen , it is ctf, I will give you a hint the flag is more than 6 characters, where did you stop? |
