Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert object.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

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

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

  // The file path is relative to the application's current working directory.  An absolute path
  // may also be used.  Supply the path appropriate to your own environment.
  // The PFX password should come from a secure source rather than being hard-coded.
  const password = 'myPfxPassword';
  try {
    pfx.loadPfxFile('qa_data/identity.pfx', password);
  } catch {
    console.log(pfx.lastErrorText);
    return;
  }

  // Find a certificate whose certificate-bag localKeyId attribute matches the given value.  The 2nd
  // argument names the binary representation of the id, such as decimal, base64, or hex.
  const cert = new Cert();
  try {
    pfx.certByLocalKeyId('01', 'hex', cert);
  } catch {
    console.log(pfx.lastErrorText);
    return;
  }

  console.log(`Found certificate: ${cert.subjectCN}`);
