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).

import 'package:chilkat/chilkat.dart';

void main() {
  final jwe = CkJwe();

  // Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
  // member names the content-encryption algorithm.
  final header = CkJsonObject();
  header.updateString('alg', 'A256KW');
  header.updateString('enc', 'A256GCM');

  // Set the protected header on the JWE.  The protected header is integrity-protected and applies to
  // all recipients.
  try {
    jwe.setProtectedHeader(header);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Protected header set.');
