Examples of using Cython to encrypt python source code for distribution.

Cython Encryption for Distributing Python Source Code

In this package, we show how to encrypt the Python source code for distribution. The workflow is:

1. compile all needed files to so file on Mac/Linux, or pyd file on Windows.
2. distribute the compiled lib directory.

NOTE: Cython does not support relative imports, so you should always use absolute imports in your package. See cython_encrypt/enc_local_import.py for example.

NOTE: Cython does not keep the structure of modules (no need for __init__.py). To import the module, treat the module as a bunch of files located in a same directory.

We include these frequently used packages:

• Numpy
• Pandas
• PyTorch
• Custom class

We also include the following patterns for encryption

• bash script (in bin/)
• submodules

Have fun coding!
