A certificate contains information about its issuer. This example demonstrates how to get the issuer information from a certificate. React Native

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

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

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

  // Get issuer information:

  // (Not all subject fields may exist depending on the issuer certificate.)

  // Issuer DN (Distinguished Name, i.e. all the Issuer subject parts)
  console.log(`DN: ${cert.issuerDN}`);

  // Common Subject parts:
  // Issuer Common Name
  console.log(`CN: ${cert.issuerCN}`);

  // Issuer Country
