Sign a JWS with an HMAC Key from BinData

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.SetMacKeyBd, which sets the symmetric MAC key for a signature from the raw bytes in a BinData.

Background. This is the in-memory equivalent of SetMacKey, for when the key material is already available as bytes.
