📦 Project name - SentinelSecrets

🔐 Secret Scanner for CI/CD & Git Hooks

SentinelSecrets is an open-source tool for preventing secret leaks (API keys, tokens, passwords) in Git repositories and CI/CD.The project integrates directly into the development process via Git hooks, blocking a commit if a secret is detected in it.

🎯 Project Summary

A tool that automatically prevents secrets (API keys, tokens, passwords) from leaking before code is pushed to the repository:

• Checks git diffs before committing

• Uses regular expressions + entropy analysis

• Suitable for local development and CI/CD

• Generates reports in JSON and Markdown

• Has a REST API with OpenAPI (Swagger)

✅ Benefits and Problems Solved

• Leak Prevention: Stops secrets from leaking into public and corporate repositories.
• Risk Mitigation (Shift Left Security): Security is checked at the coding stage, not after deployment.
• Audit Automation: Report generation in JSON format allows for easy integration into corporate security dashboards.

Git pre-commit hook

🌐 REST API (Swagger)

Swagger will be available on:

http://localhost:8000/docs

🚀 Features

• 🔍 Regex search (AWS, GitHub, JWT, passwords)
• 🔐 Entropy analysis (Shannon entropy)
• 🧠 False positive minimization
• 🪝 Git pre-commit integration
• 📄 Reports: JSON / Markdown / HTML
• 📊 HTML report with graphs (Chart.js)
• ❌ Commit locking on leak

Installation

git clone https://github.com/mscbuild/sentinel-secrets-.git
cd sentinel-secrets-
pip install -r requirements.txt

Usage

python main.py --file app.py

Architecture

• scanner.py — signatures and search logic

• entropy.py — random secret detection

• git_utils.py — working with git diff

• api.py — REST API

Threats this addresses

• API key leaks to public repositories

• Cloud account compromise

• SOC2/ISO 27001 compliance violations

• Supply chain attacks

🧪 How to run tests

pip install pytest
pytest -v

Important

Use git filter-repo (recommended) or BFG Repo-Cleaner to remove secrets from Git history.

Note

My project is lightweight, customizable to the company's internal formats, and written in pure Python for easy auditing.

🛡️ Security

This project is developed in compliance with the OWASP Code Review Guide.
