Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

import 'package:chilkat/chilkat.dart';

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

  // Protected header: PBES2 password-based key management with AES-128-GCM content encryption.
  final header = CkJsonObject();
  header.updateString('alg', 'PBES2-HS256+A128KW');
  header.updateString('enc', 'A128GCM');
  try {
    jwe.setProtectedHeader(header);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
  // being hard-coded.
  final password = 'myPassword';
  try {
    jwe.setPassword(0, password);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final String jweCompact;
  try {
    jweCompact = jwe.encrypt('This is the secret content.', 'utf-8');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(jweCompact);
