# pyarmor.cli.core.linux — Provide pre-built extension modules `pytransform3` and `pyarmor_runtime` for Pyarmor

License: unclear · Maintenance: active · Downloads: 162.2K/mo

## What it is and what it does

Pyarmor.cli.core.linux is a platform-specific extension package that supplies pre-built runtime modules for Python script obfuscation on Linux. It provides the pytransform3 and pyarmor_runtime modules that enable obfuscation by renaming identifiers, converting functions to C, and binding scripts to specific machines or expiration dates. The package supports Python 3.7 through 3.14 and multiple architectures.

Obfuscated scripts remain as standard .py files that import from the runtime modules supplied by this package, allowing them to replace originals in most deployment scenarios. The free trial version never expires but has feature limitations; commercial licensing is available for unrestricted use.

Use it for:

- Protect proprietary Python source code from reverse engineering before distribution.
- Bind obfuscated scripts to specific machines to prevent unauthorized copying or execution elsewhere.
- Set expiration dates on obfuscated scripts to enforce license terms or time-limited trial periods.
- Convert performance-critical Python functions to C for both security and speed improvements.
- Deploy Python applications on Linux where source code confidentiality is required.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Pyarmor.cli.core.linux provides pre-built extension modules for Python script obfuscation, machine binding, and expiration-date enforcement on Linux systems.

Yes, if you need Python script obfuscation on Linux and accept the 'Free To Use But Restricted' license terms. Install friction is low and maintenance is active. Verify that the free trial's limitations meet your use case and review the EULA carefully before production or commercial deployment.

## Install

pip install pyarmor-cli-core-linux
uv add pyarmor-cli-core-linux
poetry add pyarmor-cli-core-linux

## Installing pyarmor.cli.core.linux

Before you install: Low friction installation with wheels available for Python 3.7 through 3.14 on Linux. Actively maintained as of 2026-08-14 with recent releases.

License in practice: Licensed as 'Free To Use But Restricted' with no SPDX identifier. The free trial version has limitations; commercial use or full features require a paid license. Review the EULA before deployment.

Quickstart:

pip install pyarmor-cli-core-linux
from pyarmor_runtime import __pyarmor__
__pyarmor__(__name__, __file__, b'...')

Linux system required; this package provides platform-specific pre-built modules only.

Verify before relying:

- Exact scope of 'limitations' in the free trial version and which features require paid licensing
- Whether this package functions as a standalone tool or only as a runtime dependency
- Performance overhead of obfuscation and C-function conversion on typical workloads
