Considering this, what is JWT used for?
JSON Web tokens(JWT) is a standard for representing claims securely between two parties. It is quite secure because the JWT can be signed using a secret or public/private key.
Likewise, what should JWT contain? Unserialized JWTs have two main JSON objects in them: the header and the payload . The header object contains information about the JWT itself: the type of token, the signature or encryption algorithm used, the key id, etc. The payload object contains all the relevant information carried by the token.
One may also ask, what is JWT and how it works?
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. Signed tokens can verify the integrity of the claims contained within it, while encrypted tokens hide those claims from other parties.
How do you sign a JWT?
A party uses its private party to sign a JWT. Receivers in turn use the public key (which must be shared in the same way as an HMAC shared key) of that party to verify the JWT. The receiving parties cannot create new JWTs using the public key of the sender.
