Set the JWS Payload

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetPayload, which sets the content to be signed. The charset converts the text to bytes, and a flag controls whether a byte-order mark is included.

Background. JWS (JSON Web Signature) integrity-protects a payload with a signature or MAC. The header alg names the algorithm; this example uses HMAC-SHA256 (HS256) with a symmetric MAC key.
