[RevEng] Challenge/keygenme #88

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.

Good luck!
