Python Obfuscated KeygenMe 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! File Information Submitter musava_ribica …

.NET KeyGenMe by Freddy #1 Hey there! I made this KeyGenMe because I enjoy playing chess.

Fully KeyGen it - every username with different serial key algorithm ( Silver ) 3. Full KeyGen plus EXPLANATION on what u did and how you figured o…
