 Do you know what a JWT is? JWT, also pronounced as Jot, stands for JSON Web Token. It's a compact way to securely transmit information between two parties in a JSON object. A JWT has three parts. It has the header, the payload, and the signature. The header includes two parts, the token type, and the signing algorithm that was used. The payload has claims. Claims typically include information about the user. To create the signature, take a base 64 encoded version of the header, and the payload, a secret, and the algorithm specified in the header, and then sign all of that. The output will have each section separated by three dots. The signature verifies the message was in chains along the way, and if you sign it with the private key, it also verifies the sender of the JWT is who they say they are.
