Set the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetProtectedHeader, which sets the integrity-protected JWE header from a JsonObject. The header specifies the key-management algorithm (alg) and content-encryption algorithm (enc).

Background. The protected header is integrity-protected and applies to all recipients. It is configured before encrypting.
