Cython protection python code

Note: .pyc also have some protection, easy to decompile the source code ...

 

When publishing project, in order to prevent disclosure of the source code, the source code needs to be a protective mechanism, as used herein, Cython the .py file into .so protection. This approach, though still can decompile, but the difficulty will be relatively large. In addition, Cython is a superset of Python.

Self-installation Cython

 

1. Create a file complie.py

from Cython.Build import cythonize
from Cython.Distutils import build_ext
from setuptools import setup
from setuptools.extension import Extension

setup(
    ext_modules=cythonize(
        [
            Extension('project.*', ['project/*.py']),
            Extension('project.api.*', ['project/api/*.py']),
            Extension('project.api.bizs.*', ['project/api/bizs/*.py']),
            Extension('project.api.data.export*', ['project/api/data/export/*.py']),
            Extension('project.api.exceptions.*', ['project/api/exceptions/*.py']),
            # 需要保护的.py文件目录写在此处
        ],
        build_dir='build',
        compiler_directives=dict(
            always_allow_keywords=True, language_level=3
        )
    ),
    cmdclass=dict(
        build_ext=build_ext
    )
)

language_level representatives python3 version, python2 wrote 2

 

2, run the command: python compile.py build_ext --inplace

 .Py will be generated for each file in each directory .so files, and a build folder. .py file has been protected, you can call each other a .so file.

Deleted deployment project .py files, build folders.

 

If the project uses celery, celery careful not to compile the code, or celery can not be used.

Posted a shell script, with the upper section of code uses.
