sh1r0 on 2023-07-05 17:14: Patch was very easy, it was necessary in the function "check" to change "return s1 == this.Key3(name) & s3 == this.Key2(name) & s2 == this.Key1(name);" to "return true;" and all, of course I tried to change the code generator but it did not work, crackme was very exciting thanks for the experience!

incon on 2023-08-01 11:42: not very familiar with c#, so this had me stumped for a bit, but i did keygen it!

This was a nice opportunity to learn dnSpy a bit. There's a subtle bug (or purposeful subterfuge) in the key verification that's easy to miss.

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 - Python script for final key, require Python 3.x and maybe working on Python 2.x
