navneetak16/Free-Fire-UID-Bypass ? reverse-engineered prompt

Build me a Python mitmproxy addon that can sit between a client and a server, intercept one specific HTTPS login request, decrypt the encrypted body, read and edit a few Protobuf fields without needing a proto file, then put everything back together and forward it on.

I want it to keep all other fields exactly as they came in, preserve the original order, and print clear logs showing the message before and after the change. It should work with mitmproxy and mitmweb, and be easy to run with a single script. Please include the encryption and decryption part, the Protobuf wire format handling, and the field edits I described in the README.

Make it practical for security research and protocol analysis, with simple setup instructions and sensible defaults. If you need to check current mitmproxy or cryptography docs online, go ahead.
