Apple Keychain - Get Certificate by Common Name

See more Apple Keychain Examples

Retrieves the certificate from the Apple Keychain that matches the specified common name (CN).

Note: This example requires Chilkat v10.0.0 or greater.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
  // having the specified CN.
  final cert = CkCert();
  try {
    cert.loadByCommonName('Certum CA');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(cert.subjectDN);

  // Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
  // When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
  // You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
  final cert2 = CkCert();
  try {
    cert2.loadByCommonName('Chilkat Software, Inc.');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(cert2.subjectDN);
  final hasPrivKey = cert2.hasPrivateKey();
  print('Has private key: $hasPrivKey');

  print('Success.');
