SecretShield v0.13.2 is here!
I've been working on SecretShield, an open-source tool for detecting and redacting exposed secrets such as API keys, tokens, passwords, and credentials.
With v0.13.2, I've reached a major milestone: standalone builds for Windows, macOS, and Linux.
What is SecretShield?
SecretShield helps developers find exposed secrets in their source code and application output.
Some of its features include:
- Static secret scanning
- Runtime redaction for stdout, stderr, and logging
- Custom detection rules
- Git hooks and GitHub Actions integration
- SARIF export
- Secret detection across multiple providers
The project is local-first, with no telemetry or network calls.
What's new in v0.13.2?
Previously, installing SecretShield generally required Python, pip, and a configured environment.
That changes with this release.
SecretShield now has standalone distributions for:
- Windows
- macOS
- Linux
Windows also gets an installer and a portable ZIP.
The goal was to make SecretShield easier to install and use, even for people who don't work with Python.
Building the standalone distributions
This release involved quite a bit of work beyond simply creating executables.
Some of the challenges included:
- Cross-platform packaging
- Frozen executable compatibility
- Windows Unicode handling
- Installer and upgrade behaviour
- PATH integration
- Automated installation testing
There were multiple CI failures along the way, especially with Windows-specific behaviour. Getting the installer tests to pass was a significant milestone.
Getting started
If you already have Python installed:
pip install --upgrade secretshield You can also find the standalone distributions on GitHub.
GitHub: https://github.com/Sam3360/secretshield
PyPI: https://pypi.org/project/secretshield/
Website: https://therealsecretshield.freebuff.app/
What's next?
I'm focusing on stabilising the project and completing its final development milestones.
Building SecretShield has been a great learning experience in Python, security tooling, packaging, cross-platform compatibility, and open-source development.
If you check it out, I'd appreciate feedback on the installation experience and how the tool works.
Thanks for reading!
