What is JSON Web Token (JWT)

JSON Web Token (JWT), as an open standard (RFC 7519), defines a concise and self-contained method for the secure transmission of information in the form of JSON objects between two parties of communication. Because of the digital signature, the information of these communications can be verified and trusted.

JWT can use the secret key (secret) for signature (using the HMAC algorithm) or the public / private key pair (public/private key) of the RSA or ECDSA algorithm.

Although JWT can sign between the two parties of the communication by providing a secret, we will pay more attention to * * signed (signed) * * token.

The data integrity (integrity) in it can be verified by signed tokens, while encrypted tokens can be hide claims against other parties.

When a token (token) is signed with a public key / private key pair (public/private key), only the party who holds the private key to sign is signed.
