And Pyarmor works well with py2exe, py2app, PyInstaller, cx_Freeze etc.

The byte code of each code object will be obfuscated as soon as code object completed execution, and f_locals of frame is cleared at the same time

It can protected those Python source files distributed as package

Pack Obfuscated Scripts

Pyarmor could pack obfuscated scripts with PyInstaller, py2exe, py2app, cx_Freeze etc.

Different Licenses
