Clear the S/MIME Recipient Certificate List

See more MIME Examples

Demonstrates ClearEncryptCerts, which empties the recipient-certificate list previously populated by AddEncryptCert. This is useful to start over with a different set of recipients before calling EncryptN.

import 'package:chilkat/chilkat.dart';

void main() {
  final mime = CkMime();
  try {
    mime.setBodyFromPlainText('This message will be encrypted.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Add a recipient certificate.
  final cert = CkCert();
  try {
    cert.loadFromFile('qa_data/recipient.cer');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  try {
    mime.addEncryptCert(cert);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // ClearEncryptCerts empties the recipient-certificate list, for example to start over with a
  // different set of recipients before calling EncryptN.  It is a void method.
  mime.clearEncryptCerts();

  print('Recipient certificate list cleared.');
