## What it is
Pyarmor is a command-line tool for obfuscating Python scripts, making them hard to reverse-engineer. It also supports binding obfuscated scripts to specific machines and setting expiration dates for them.

## Use cases
- obfuscate python scripts to protect source code
- bind python scripts to a specific machine
- set an expiration date for distributed python scripts
- protect python code before distributing to customers
- pack obfuscated python scripts with pyinstaller
- rename functions and variables so decompilers fail

## When to choose
- you distribute Python scripts and need to hide the source code
- you want to enforce machine-locked or time-limited licenses on Python code
- you need obfuscation that works across Windows, Linux, macOS, and embedded systems

## When to avoid
- you need a permissive open-source license - Pyarmor is shareware with trial limitations
- you only need simple bytecode compilation (.pyc) rather than strong obfuscation
- you require guaranteed compatibility with all Python versions and exotic platforms

## Facets
- artifact type: cli-tool
- maturity: active
- function: security, cli, developer-tools
- domain: security, developer-tools
- platform: python, windows, cross-platform, cli
- tags: obfuscation, code-protection, script-binding, license-expiration, python-bytecode, command-line, linux, macos
