If you get a 'Welcome' message, does it means you solved it ?

Pretty fun. My very first crackme :)

Hmm, not sure if it takes away the fun or is just the new way of doing things... but I just used a decompiler and put the somewhat complicated looking luna function into ChatGPT - which spilled the beans. "Now give me a number that will pass it". EzPz

@b3n the whole point is just to learn. The simpler ones are a good opportunity to try out new techniques. It's cool that you were able to find a way to solve it with ChatGPT, but then try a different approach on the next one, and so on. Then submit writeups so we can learn too!

I have just started out with studying reverse engineering and this task was great for a beginner like me. Thank you!

Solution by cnathansmith on 2023-09-17 08:14: Walkthrough and keygen source code implementing the atypical approach of converting the target into a shared library to directly interface with program functions externally
Solution by bang1338 on 2023-09-26 13:21: A writeup of my process and solution.
In zip file contain:
- Bunch of image instead hosted on Discord
- a markdown, which is my writeup and solution. Require a GitHub-like markdown reader like Markdown Monster
- A Python script to solve, require Python 3.x
- A decompiled source code of luna crackme (C++, recommend gcc)
