Structure of a JWT token

Let’s take a look at the structure of a JWT token:

The token is base64 encoded and consists of three parts:

• header

• claims

• signature

Both header and claims consist are represented by a JSON object. The header describes the cryptographic operations applied to the JWT and optionally, additional properties of the JWT. The claims represent a JSON object whose members are the claims conveyed by the JWT.
