How do I protect Python code? [closed]

Answer 1

Long story short:

1. Encrypt your source code
2. Write your own python module loader to decrypt your code when importing
3. Implement the module loader in C/C++
4. You can add more features to the module loader, for example anti-debugger, license control, hardware fingerprint binding, etc.
