Dart Requires Chilkat v11.0.0+

Get the Server Certificate, Certificate Chain, and Root CA Certificate

See more HTTP Examples

Demonstrates how to get the HTTP server certificate, its certificate chain, and the root CA certificate. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // We're getting the SSL/TLS certificate, so make sure to connect to the SSL/TLS port (443).
  final sslCert = CkCert();
  try {
    http.getServerCert('apple.com', 443, sslCert);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final certChain = CkCertChain();
  try {
    sslCert.buildCertChain(certChain);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final cert = CkCert();
  var i = 0;
  final numCerts = certChain.numCerts;
  while (i < numCerts) {
    certChain.certAt(i, cert);
    print('SubjectDN $i: ${cert.subjectDN}');
    print('IssuerDN $i: ${cert.issuerDN}');
    i++;
  }

  // If the certificate chain reaches the root CA cert, then the last cert in the chain
  // is the root CA cert.
  if (certChain.reachesRoot) {
    final caCert = CkCert();
    certChain.certAt(numCerts - 1, caCert);
    print('CA Root Cert: ${caCert.subjectDN}');
