Experience

I created this project from scratch as an open source tool

Redflag is a lightweight, cross-platform secret scanner designed to identify potentially sensitive information in codebases. Built with Rust for performance and reliability, it helps developers and security teams detect exposed secrets, API keys, and credentials before they reach production environments.

Redflag

The Challenge

Development teams often accidentally commit sensitive information like API keys, passwords, and tokens to version control systems. Traditional security scanning tools are often heavy, slow, or lack comprehensive git history analysis capabilities, leaving organizations vulnerable to credential exposure.

My Contributions

Architected and implemented a high-performance secret scanning engine using Rust. Developed advanced pattern matching with regex support, Shannon entropy detection for high-entropy strings, and comprehensive git history analysis. Created flexible configuration system with custom exclusion policies and multiple output formats including JSON for CI/CD integration.

Results & Impact

The tool provides fast, accurate secret detection across multiple file types with configurable severity levels. Its git history scanning capabilities allow teams to audit entire repository histories, while the lightweight design ensures minimal impact on development workflows. The cross-platform support and GitHub Actions integration make it accessible for teams of all sizes.
