Enumerate Server-Advertised Acceptable Client CAs

See more Socket/SSL/TLS Examples

Demonstrates Socket.GetSslAcceptableClientCaDn, which returns a certificate-authority distinguished name advertised by a TLS server when it requests a client certificate.

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;
  }

  // After connecting to a server that requests a client certificate, enumerate the certificate-
  // authority distinguished names the server advertised as acceptable.
  final numCAs = socket.numSslAcceptableClientCAs;
  for (var i = 0; i < numCAs; i++) {
    final String caDn;
    try {
      caDn = socket.getSslAcceptableClientCaDn(i);
    } on ChilkatException catch (e) {
      print(e.lastErrorText);
      return;
    }

    print(caDn);
  }
