Set the Decryption Certificate and Private Key

See more Email Object Examples

Demonstrates the Chilkat Email.SetDecryptCert2 method, which explicitly provides a certificate and its corresponding private key as separate objects for decrypting a received encrypted email. Set them before loading the encrypted message. This example loads a .cer certificate and a PEM private key, sets both, then loads an encrypted email.

import 'package:chilkat/chilkat.dart';

void main() {
  // Demonstrates the SetDecryptCert2 method, which explicitly provides a certificate and its
  // corresponding private key (as separate objects) for decrypting a received encrypted
  // email.  Set them before loading the encrypted email.

  final email = CkEmail();

  // Load the certificate (public) and the matching private key from separate files.
  final cert = CkCert();
  try {
    cert.loadFromFile('qa_data/certs/recipient.cer');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final privKey = CkPrivateKey();
  try {
    privKey.loadPemFile('qa_data/certs/recipient_privkey.pem');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Provide the certificate and private key to use for decryption.
  try {
    email.setDecryptCert2(cert, privKey);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Load the encrypted email; Chilkat decrypts it using the certificate and key.
  try {
    email.loadEml('qa_data/eml/encrypted.eml');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Decrypted = ${email.decrypted}');
