pyarmor 4.4.1

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

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 foo.py is obfuscated by Pyarmor. Here are the files list in the output path dist:

foo.py

pytransform.py
_pytransform.so, or _pytransform.dll in Windows, or _pytransform.dylib in MacOS

pyshield.key
pyshield.lic
product.key
license.lic

dist/foo.py is obfuscated script, the content is:

from pytransfrom import pyarmor_runtime
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/foo.py can be used as normal Python script.

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

Support Platforms

• Python 2.5, 2.6, 2.7 and Python3

• win32, win_amd64, linux_i386, linux_x86_64, macosx_x86_64

• Embedded Platform: Raspberry Pi, Banana Pi, TS-4600 / TS-7600

Quick Start

Install:

pip install pyarmor

Obfuscate scripts:

pyarmor obfuscate examples/simple/queens.py

Run obfuscated scripts:

cd dist
python queens.py

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

pip install pyinstaller
pyarmor pack examples/py2exe/hello.py

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/
python queens.py
