JWS JSON Serialization Overview

A JWS is represented as the concatenation of

BASE64URL(UTF8(JWS Protected Header)) || '.' ||
BASE64URL(JWS Payload) || '.' ||
BASE64URL(JWS Signature)

In the JWS JSON Serialization, a JWS is represented as a JSON object containing some or all of these four members:

  • protected, with the value BASE64URL(UTF8(JWS Protected Header))
  • header, with the value JWS Unprotected Header for example
    {"alg":"HS256"}
    Encoding this JWS Protected Header as BASE64URL(UTF8(JWS Protected Header)) gives this value:
    eyJhbGciOiJIUzI1NiJ9
  • payload, with the value BASE64URL(JWS Payload) for example the payload
{
  "sub": "1234567890",
  "name": "Anish Nath",
  "iat": 1516239022
}

Encoding this JWS Payload as BASE64URL(JWS Payload) gives this value
