sab24 on 2020-12-21 17:14: Hi Chris, I have the solution, but creating a program that generates passwordkeys is a bit tricky as rand is implementation dependent and I am unsure what you used, I think mingw32. I tried to submit a solution, but it apparently requires an attachment. Anyway, I liked the challenge, and I think it is level 2 for finding a solution but level 3 for implementing a working keygen.

chrisK on 2020-12-21 17:17: Did you search the data section ?? or you bruteforce everything ?

Explained the two stages. Added the keygen code and the little Easter egg in the flagspace
