About JWTs

JSON Web Tokens (JWTs) are a compact, URL-safe means of representing claims to be transferred between two parties. They consist of three parts: a header (algorithm & type), a payload (claims), and a signature. This tool decodes the header and payload but cannot verify the signature without the secret key.
