Set the JWS Payload from BinData

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetPayloadBd, which sets the payload to be signed from the binary bytes in a BinData.

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.
