PyArmor
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.
