Get the Server Certificate from a TLS Connection

See more Socket/SSL/TLS Examples

Demonstrates Socket.GetServerCert, which copies the certificate presented by the remote TLS server into a Cert object for inspection.

import 'package:chilkat/chilkat.dart';

void main() {
  final socket = CkSocket();

  // Connect to the server using TLS.
  final bTls = true;
  final maxWaitMs = 5000;
  try {
    socket.connect('example.com', 5000, bTls, maxWaitMs);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Copy the certificate presented by the remote TLS server, then inspect it.  This can be used to
  // validate the server's identity.
  final cert = CkCert();
  try {
    socket.getServerCert(cert);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Server certificate subject: ${cert.subjectCN}');
  print('Issued by: ${cert.issuerCN}');
