JWT Encoder: Create and Sign JSON Web Tokens for Authentication
Learn how JWTs work, understand signing algorithms, and create tokens for stateless API authentication.
What Is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe token format used for securely transmitting information between parties as a JSON object. A JWT consists of three Base64URL-encoded parts separated by dots: header.payload.signature. The header specifies the signing algorithm, the payload contains the claims (data), and the signature verifies the token has not been tampered with.
