Brute-Force Polynomial for Coefficients.

By Benten

Here is a keygen challenge I got recently. This one requires to find the coefficients of a 26th degree polynomial that sums up to a specific value. A valid serial is also provided. The challenge is to code a keygen with least / reasonable time complexity without patching anything.
Update: Added my initial code that barely works. Please let me have your suggestions to improve the code.

This is a little past time project I have been working on, here I put an interesting spin to conventional c# obfuscation.
Try to unpack this file or at least keygen it.

Hi
I got this keygenme in my hard drive, this is from CIN1TEAM and created by MR. Teo.
Thought this might help someone to test his keygenning skill.

Thanks

The real goal is to make a keygen capable of generating infinite valid combinations of name and keys.
Btw, also a valid serial is appreciated
The only protection used is renaming.
Good luck!
