Dart Requires Chilkat v11.0.0+

Export Public Key from USB Token or Smartcard using the Apple Keychain

See more Apple Keychain Examples

Demonstrates how to export a public key from a USB token or smart card via the Apple Keychain. 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.

  final cert = CkCert();

  // On MacOS and iOS, the LoadByCommonName function will search the Apple Keychain for the matching certificate.

  // A digital certificate's Common Name (CN) is a field in the certificate that specifies the name of the entity the 
  // certificate is issued to. It is often used to identify the domain name, hostname, or organization the certificate represents. 

  // For example:
  // - In an SSL/TLS certificate for a website, the CN typically contains the domain name (e.g., "www.example.com").
  // - For certificates representing individuals or organizations, the CN might include the person's name or the organization's name.

  // The CN is part of the certificate's Subject field and is crucial for verifying that the certificate corresponds 
  // to the intended entity, especially in SSL/TLS communications.

  try {
    cert.loadByCommonName('Test 2048 bit RSA');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final pubKey = CkPublicKey();
  cert.getPublicKey(pubKey);

  try {
    pubKey.savePemFile(false, 'rsaKeys/Test2048Rsa.pem');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
