How can you secure your Python application code?

Question

Python

Hello. I have an API in python. This "API" includes the so-called. "router" - part of the API that redirects requests to the kernel. This router is started with gunicorn. There are also several extremely important classes in the API that I would also like to protect. These classes are imported into unprotected open source files. By protection, I mean the inability to somehow get the source code of individual parts of the application (not at all). How can this be implemented?

Answer 1

Rewrite them in Cython and compile to pyd.

Answer 2

Any code that you give to the side can be reverse engineered, no matter how you protect it (the only question is the desire to receive this code).
Therefore, either just score on defense, or not give the code (execute on your side).
The other is not given a priori. You can accept this and live in peace, or you can not accept it and continue to fight windmills.
