Demonstrates how to get a certificate's policy OIDs (if any) React Native

import { Cert, Xml } from '@chilkat/react-native'

function chilkatExample() {
  const cert = new Cert();

  try {
    cert.loadFromFile('qa_data/certs/sample.cer');
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  // The certificatePolicies OID is 2.5.29.32
  const oid = '2.5.29.32';
  try {
    const strXml = cert.getExtensionAsXml(oid);
    console.log(strXml);

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

    const xml = new Xml();
    xml.loadXml(strXml);
    console.log(`Policy OID = ${xml.getChildContent('sequence|oid')}`);
  } catch {
    // cert.getExtensionAsXml() failed; continue anyway.
  }
