A tool used to obfuscate python scripts, bind obfuscated scripts to fixed machine or expire obfuscated scripts.

Project description

PyArmor is a command line tool used to obfuscate python scripts, bind obfuscated scripts to fixed machine or expire obfuscated scripts. It protects Python scripts by the following ways:

  • Obfuscate code object to protect constants and literal strings.
  • Obfuscate co_code of each function (code object) in runtime.
  • Clear f_locals of frame as soon as code object completed execution.
  • Verify the license file of obfuscated scripts while running it.

Look at what happened after is obfuscated by PyArmor. Here are the files list in the output path dist:, or _pytransform.dll in Windows, or _pytransform.dylib in MacOS

dist/ is obfuscated script, the content is:

from pytransform import pyarmor_runtime

__pyarmor__(__name__, __file__, b'\x06\x0f...', 1)

All the other extra files called Runtime Files, which are required to run or import obfuscated scripts. So long as runtime files are in any Python path, obfuscated script dist/ can be used as normal Python script.

The original python scripts can be replaced with obfuscated scripts seamlessly.

Quick Start


pip install pyarmor

Obfuscate scripts:

pyarmor obfuscate examples/simple/

Run obfuscated scripts:

cd dist

Pack obfuscated scripts with PyInstaller, py2exe, cx_Freeze etc.:

pip install pyinstaller
pyarmor pack examples/py2exe/

Generate an expired license and run obfuscated scripts with new license:

pyarmor licenses --expired 2018-12-31 Customer-Jondy
cp licenses/Customer-Jondy/license.lic dist/

cd dist/

Start webui, open web page in browser for basic usage of PyArmor:
