   Python Obfuscated KeygenMe

   By musava_ribica

   I have provided a zip archive which contains two .py files, as seen in the screenshot. In LicenseChecker.py there is a validation function invoked by main.py where you put the key in the given format.
   The python code is obfuscated using a obfuscator I'm currently working on. If you solved the challenge, or have any feedback to give, or need hints/help with reversing without spoiling, please let me know. Thanks.
    
   You can see original source code and the solution in the 'Authors Code' and 'Authors Solution', if you wish.
   Good luck!

   WinLicense 3.1.4.32

   By InvizCustos

   A simple console application that displays the HWID and asks you to enter an "activation key" for it.
   Key format: xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx
   The solution will be a description of the algorithm to generate an activation key for any HWID value (there is no need to write code).

   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.

    By LoLLo90

    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!
