sensleak is a Rust-based tool that scans Git repositories for sensitive data, specifically targeting sensitive information such as passwords, API keys, certificates, and private keys embedded within code.
Many developers store sensitive information such as keys and certificates in their code, which poses security risks. Therefore, there are commercial services like GitGuardian scanning GitHub and GitLab, as well as open-source components like truffleHog and Gitleaks that support similar functionalities.
- Enhanced Security. Develop the tool in Rust to ensure improved security and memory safety.
- Command-line Interface. Create a user-friendly command-line tool that generates a comprehensive test report.
- REST API with Access Control. Enable the tool to run as a service and provide access control through a REST API. Utilize Swagger to generate API documentation.
- Concurrent Scanning. Utilize a thread pool to control concurrent scanning of secrets, thereby improving overall efficiency.
- Batch Processing. Implement batch processing of files to further optimize the scanning process and enhance efficiency.
- Development Language: Rust
- Command-line Interaction: clap.rs
- Git Repository Operations: git2
- Web Framework: axum
- Auto-generated OpenAPI Documentation: utoipa
Running the tool in the command-line interface (CLI) to perform sensitive data checks.

- Review the Contributing Guidelines. This document outlines the process for submitting bug reports, feature requests, and pull requests to sensleak-rs.
- Sign the Developer Certificate of Origin (DCO) by adding a
Signed-off-byline to your commit messages. This certifies that you wrote or have the right to submit the code you are contributing to the project. - Choose an issue to work on. Issues labeled
good first issueare suitable for newcomers. You can also look for issues markedhelp wanted. - Fork the sensleak-rs repository and create a branch for your changes.
- Make your changes and commit them with a clear commit message.
- Push your changes to GitHub and open a pull request.
- Respond to any feedback on your pull request. The sensleak-rs maintainers will review your changes and may request modifications before merging.
- Once your pull request is merged, you will be listed as a contributor in the project repository and documentation.
To comply with the requirements, contributors must include both a Signed-off-by line and a PGP signature in their commit messages. You can find more information about how to generate a PGP key here.
Git even has a -s command line option to append this automatically to your commit message, and -S to sign your commit with your PGP key. For example:
$ git commit -S -s -m 'This is my commit message'sensleak-rs is licensed under this licensed:
