⨠Key Features
JWT Support: Decode and generate JSON Web Tokens
PASETO Support: Decode PASETO tokens (v2, v4)
Real-time Decoding: See results as you type
Token Generation: Create JWT tokens with custom payloads
Syntax Highlighting: Color-coded JSON output
Copy Functions: One-click copy for all sections
100% Client-Side: All processing in your browser
Privacy-First: Tokens never sent to any server
đ What are these tokens?
JWT: JSON Web Token is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. Commonly used for authentication.
PASETO: Platform-Agnostic SEcurity TOkens - a more secure alternative to JWT, designed to avoid common cryptographic pitfalls.
đ Privacy & Security
All token processing happens entirely in your browser. Your tokens are never transmitted to any server, stored, or logged. For generation, we use JavaScript crypto libraries - in production, always use proper server-side implementations.
