Happy New Year!
This is my new challenge/keygenme.
Those, who can write a keygen for it, will be inducted to a hall of fame (here, in this blog post) and will get a lifetime membership of my club.
It's practically possible to make a keygen for it. My full write-up about it will be posted someday in summer 2022 maybe.
I can't say it's easy. But it's doable. It's based on a real licensing scheme I once saw. I solved it maybe for a week or two. And I thought I can make a good example/tutorial out of it.
If you can solve it faster, you can have bragging rights, as they say.
Download it. You can use 7-Zip to unpack TAR on Windows.
Send me your solutions.
