Pyarmor

Pyarmor is a command-line tool designed for obfuscating Python scripts, binding obfuscated scripts to specific machines, and setting expiration dates for obfuscated scripts.

Key Features

Seamless Replacement: Obfuscated scripts remain as standard .py files, allowing them to seamlessly replace the original Python scripts in most cases.
Balanced Obfuscation: Offers multiple ways to obfuscate scripts to balance security and performance.
Irreversible Obfuscation: Renames functions, methods, classes, variables, and arguments.
C Function Conversion: Converts some Python functions to C functions and compiles them into machine instructions using high optimization options for irreversible obfuscation.
Script Binding: Binds obfuscated scripts to specific machines or sets expiration dates for obfuscated scripts.
Themida Protection: Protects obfuscated scripts using Themida (Windows only).

Quick start

Install Pyarmor:

shell
pip install pyarmor

Obfuscate the foo.py script:

shell
pyarmor gen foo.py

This command generates an obfuscated script like this at dist/foo.py:

python
from pyarmor_runtime import __pyarmor__
__pyarmor__(__name__, __file__, b'\x28\x83\x20\x58....')

Run the obfuscated script:

shell
python dist/foo.py
