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.
Refer to Protect Python Scripts By PyArmor
- Python 2.5, 2.6, 2.7 and Python3
- Prebuilt Platform: win32, win_amd64, linux_i386, linux_x86_64, macosx_x86_64
- Embedded Platform: Raspberry Pi, Banana Pi, Orange Pi, TS-4600 / TS-7600
Refer to docs/platforms.rst
Installation

Start webui, open web page in browser for basic usage of PyArmor
pyarmor-webui
More usage, refer to Examples, Documentation
PyArmor is published as shareware. Free trial version never expires, the limitations are
- The maximum size of code object is 35728 bytes in trial version
- The scripts obfuscated by trial version are not private. It means anyone could generate the license file which works for these obfuscated scripts.
About the license file of obfuscated scripts, refer to The License File for Obfuscated Script
A registration code is required to obfuscate big code object or generate private obfuscated scripts.
- Personal user: one registration code is enough.
- Company user: one registration code is only used for one project/product.
For details, refer to About License.
