  const readOnly = false;
  try {
    certStore.openCurrentUserStore(readOnly);
  } catch {
    console.log(certStore.lastErrorText);

  const json = new JsonObject();
  const hexThumbprint = '767192374BE3C1512D2CB80734926D40E96D6DC2';
  json.updateString('thumbprint', hexThumbprint);

  const cert = new Cert();
  try {
    certStore.findCert(json, cert);
    // Show the full distinguished name of the certificate.
    console.log(`Found: ${cert.subjectDN}`);
