Get the JWS Payload as a String

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetPayload, which returns the payload of a loaded JWS as text, decoded using the given charset.

Background. In practice, validate the signature before trusting the payload. Getting the payload retrieves the signed content.
