  JSON Web Token

  JSON Web Token (JWT) defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

Scenarios where JSON Web Tokens are useful:

• Information Exchange: Because JWTs can be signed, JSON Web Tokens are a good way of securely transmitting information between parties.

JSON Web Tokens consist of 3 parts:

• Header
• Payload

Header consists of two parts:

• token type.
• hashing algorithm.
