Verify the Timestamp Server Token (if any) while Validating a CMS Signature

Demonstrates how to also validate the timestamp server token (if any) while validating a CMS signature. React Native

import { Crypt2, JsonObject } from '@chilkat/react-native'

function chilkatExample() {
  const crypt = new Crypt2();

  // Tell Chilkat to also validate the timestamp token if a timestamp exists in the CMS message's unauthenticated attributes.
  const cmsOptions = new JsonObject();
  cmsOptions.updateBool('ValidateTimestampTokens', true);
  crypt.cmsOptions = cmsOptions.emit();

  const outputFile = 'qa_output/original.xml';
  const inFile = 'qa_data/p7m/fattura_signature.xml.p7m';

  // Verify the signature and extract the contained file, which in this case is XML.
  try {
    crypt.verifyP7M(inFile, outputFile);
  } catch {
    console.log(crypt.lastErrorText);
    return;
  }

  console.log('Signature validated.');
}
