[KeygenMe] KeygenMe #17


Recommended Posts

This KGM is a result of quite a lot of research, so I hope you'll like it. smile.png

You'll need to be good with cryptography to solve this.

The difficulty depends on the person solving it.

  • Compiler: Delphi 7
  • Difficulty: 5 / 10
  • Accepted solutions: serial, keygen

If you solve this properly by making a keygen, I will send you a prize by PM. smile.png

Nice! Good job DE! smile.png

What gave away the signature scheme? How did you figure it out?

Been reading about digital signatures and homomorphic functions for some time already...its a leftover of a project i once did... and i knew about Paillier ... but i remember the "exp mod n²" which also came back in your code when doing the verify
