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

• 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).

• Python 2 and Python 3¹
• Windows
• Various Linux distributions, including embedded systems and Raspberry Pi
• Apple Intel and Apple Silicon
• Supported architectures: x86_64, aarch64, armv7, etc.²

For more information, check out the Pyarmor Environments.

1. Install Pyarmor:

pip install pyarmor

2. Obfuscate the foo.py script:

pyarmor gen foo.py

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

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

3. Run the obfuscated script:

python dist/foo.py
