Set an IMAP TLS Client Certificate from PEM

See more IMAP Examples

Demonstrates the Chilkat Imap.SetSslClientCertPem method, which supplies a TLS client certificate and private key from PEM. The first argument may be the PEM text itself or a path to a PEM file (Chilkat detects which), and the second is the password used when the private key is encrypted. Call it before connecting.

Note: The certificate path is relative to the application's current working directory. Supply the path to your own certificate file.

import 'package:chilkat/chilkat.dart';

void main() {
  // Demonstrates the Imap.SetSslClientCertPem method, which supplies a TLS client certificate
  // and private key from PEM.  The 1st argument is the PEM text or a PEM file path, and the 2nd
  // is the password when the private key is encrypted.  It must be called before connecting.

  final imap = CkImap();

  imap.ssl = true;
  imap.port = 993;

  // The PEM private-key password is not hard-coded in source.  Insert code here to obtain it from an
  // interactive prompt, environment variable, or a secrets vault.
  final pemPassword = '';

  // Provide the PEM client certificate BEFORE connecting.  The first argument may be a PEM file
  // path or the PEM text itself.

    imap.setSslClientCertPem('qa_data/client.pem', pemPassword);
