I built a visual, interactive tool to help developers and students understand how JWT (JSON Web Tokens) work — from token generation and structure to signature verification and expiration logic.

Features:

Visualizes JWTs in color-coded sections (Header, Payload, Signature)
Real-time decoding and validation
Expiry countdown timer
Modal walkthrough explaining how JWTs are formed and verified
Deployed using GitHub Actions + GitHub Pages

Why I built this: Understanding how JWTs work is essential in secure authentication systems. This project aims to make those concepts intuitive and transparent.

Built with just HTML, CSS, and JavaScript, and deployed through a smooth CI/CD pipeline with GitHub Actions.

I would love to hear your thoughts or suggestions! #webdevelopment #jwt #authentication #security #githubactions #developer #javascript #opensource #frontend
