Load PKCS12 / PFX and Access Contents

See more PFX/P12 Examples

Loads a PKCS12 / PFX file and iterates over the contents which include private keys and certificates. React Native

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

function chilkatExample() {
  const pfx = new Pfx();

  // Load the PKCS12 from a file
  try {
    pfx.loadPfxFile('/someDir/my.p12', 'pfxFilePassword');
  } catch {
    console.log(pfx.lastErrorText);
    return;
  }

  const numPrivateKeys = pfx.numPrivateKeys;

  const privKey = new PrivateKey();

  console.log('Private Keys:');

  let i = 0;
  while (i < numPrivateKeys) {
    pfx.privateKeyAt(i, privKey);

    // Do something with the private key ...

    i++;

  const cert = new Cert();

  const numCerts = pfx.numCerts;

  console.log('Certs:');
  i = 0;
  while (i < numCerts) {
    pfx.certAt(i, cert);
    console.log(cert.subjectDN);

    // If the certificate has a private key (one of the private keys within the PFX)
    // then it can also be obtained via the certificate object:
    if (cert.hasPrivateKey()) {

      console.log('Has private key!');

      cert.getPrivateKey(privKey);
