A JSON Web Token (JWT) is a JSON object utilized to securely transmit information between two parties over the web. Primarily employed in authentication systems, JWTs can also facilitate secure data exchange. These tokens enhance security by incorporating encryption, and for added protection, a signature can be appended. A JWT comprises a header JSON, a payload JSON, and an optional signature. Each of these components is concatenated with a period (“.”) separator....
