About JWT
JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: Header, Payload, and Signature.
- Header: Contains the token type and hashing algorithm.
- Payload: Contains the claims and user data.
- Signature: Ensures token integrity and authenticity.
Create and sign JSON Web Tokens (JWT) for secure authentication and authorization. Supports multiple algorithms including HS256, RS256, and ES256. Perfect for developers working with API authentication, single sign-on, or microservices architecture.
