• Question 425:

  What is the structure of a JSON web token?

  A. three parts separated by dots header payload, and signature

  B. header and payload

  C. three parts separated by dots version header and signature

  D. payload and signature

  Correct Answer: A

  JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is

  digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA. JSON Web Tokens are composed of three parts, separated by a dot (.): Header, Payload, Signature. Therefore,

  a JWT typically looks like the following:

  xxxxx.yyyyy.zzzzz

  The header typically consists of two parts: the type of the token, which is JWT, and the signing algorithm being used, such as HMAC SHA256 or RSA. The second part of the token is the payload, which contains the claims. Claims are

  statements about an entity (typically, the user) and additional data. To create the signature part you have to take the encoded header, the encoded payload, a secret, the algorithm specified in the header, and sign that.
