Get a JWS Protected Header
See more JSON Web Signatures (JWS) Examples
Demonstrates Jws.GetProtectedH, which copies the decoded protected header of a signature into a JsonObject.
Background. The protected header is integrity-protected by the signature. Inspecting it (for example the
alg value) is useful before deciding how to validate.Chilkat PowerBuilder Downloads
