import 'package:chilkat/chilkat.dart';

void main() {
  final cert = CkCert();

  try {
    cert.loadFromFile('qa_data/certs/sample.cer');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // The certificatePolicies OID is 2.5.29.32
  final oid = '2.5.29.32';
  try {
    final strXml = cert.getExtensionAsXml(oid);
    print(strXml);

    // Sample result:
    // <sequence><sequence><oid>2.16.840.1.101.2.1.11.39</oid></sequence></sequence>

    final xml = CkXml();
    xml.loadXml(strXml);
    print('Policy OID = ${xml.getChildContent('sequence|oid')}');
  } on ChilkatException {
    // cert.getExtensionAsXml() failed; continue anyway.
  }
