Require SSL Server Certificate Domain Match

See more HTTP Examples

Demonstrates how to require that the SSL server certificate's domain matches the intended domain. 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();

  // Call SetSslCertRequirement to require that the SSL server certificate's domain
  // matches only the domain we are intending to communicate with.

  // In this example we will test with the URL https://wrong.host.badssl.com/
  // which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

  http.setSslCertRequirement('SAN', 'wrong.host.badssl.com');

  // Also validate the server cert..
  http.requireSslCertVerify = true;

  // Try sending the request.  It should fail within the SSL/TLS handshake
  // because the server's certificate does not match the domain "wrong.host.badssl.com"
  try {
    final html = http.quickGetStr('https://wrong.host.badssl.com/');
    print('Unexpected success.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
  }
