Client Certificate in REST (USB Token or Smartcard)

See more REST Examples

Demonstrates how to use a client certificate with a REST connection where the certificate and private key are located on a USB token or smart card. Dart

import 'package:chilkat/chilkat.dart';

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

  // This example shows how to use the Chilkat socket object's connection.
  final rest = CkRest();
  final socket = CkSocket();

  // Set the certificate to be used for mutual TLS authentication
  final cert = CkCert();

  // If the smartcard or token requires a PIN...
  cert.smartCardPin = '000000';

    cert.loadFromSmartcard('');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);

  // Establish the connection using the socket object (with client certificate authentication).
  final bTls = true;

  try {

  // For example..
