About JWT
JSON Web Tokens (JWT) are an open standard for securely transmitting information between parties as a JSON object. JWTs are commonly used for authentication and information exchange.
Each JWT consists of three parts: a header (algorithm and token type), a payload (claims and data), and a signature (for verification). This tool allows you to inspect the contents of a JWT without requiring the secret key.
Security Note: All JWT processing happens locally in your browser. No tokens or secrets are sent to external servers.
