Provide extension module pytransform3 for Pyarmor
Decision gist · record as of 2026-08-14
Yes, if you are already using Pyarmor and need the native extensions on a supported platform. Install friction is minimal and maintenance is active. However, review the 'Free To Use But Restricted' license terms before using it in production, especially if you plan to distribute obfuscated code commercially.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later; platform-specific prebuilt extensions are provided for multiple architectures and operating systems (Darwin, Linux, Windows, Android, Alpine, FreeBSD) with varying support levels.
- Low install friction with a pure wheel distribution.
- Actively maintained with recent repository activity as of 2026-08-14.

What it is and what it does
pyarmor-cli-core is a support package that supplies the compiled extension modules required by Pyarmor, a command-line tool for obfuscating Python source code. It provides the low-level native extensions that perform the actual protection, binding, and expiration logic on the target platform.
The package ships prebuilt wheels for Python 3.7+ across multiple operating systems and CPU architectures, including x86_64, x86, aarch64, and specialized platforms like Android, Alpine Linux, and FreeBSD. Installation is straightforward with no build step, and the project is actively maintained. However, the license is marked 'Free To Use But Restricted' without a standard SPDX identifier, so the scope of restrictions on distributing obfuscated code is not immediately clear from the package metadata.
Use it for
- Protect proprietary Python applications from reverse engineering by obfuscating source code before distribution.
- Bind obfuscated scripts to specific machines or hardware to prevent unauthorized copying or execution.
- Create time-limited trial versions of Python applications that expire after a set date.
- Deploy Python code on untrusted systems where you need assurance that the original logic cannot be easily extracted.
- Support cross-platform obfuscation workflows on Linux, macOS, Windows, and mobile platforms like Android.
