React Native Requires Chilkat v11.0.0+

DKIM Signature using Windows Current User Certificate Store

See more DKIM / DomainKey Examples

This is a Windows-specific example to load a certificate from the Current User (registry-based) certificate store, and then use the certificate's associated private key for a DKIM signature. React Native

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

function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const cert = new Cert();

  // The LoadByCommonName method searches the Windows Local Machine and Current User 
  // registry-based certificate stores for a certificate having the common name specified. 
  // If found, the certificate is loaded and ready for use.
  try {
    cert.loadByCommonName('My Certificate ABC');
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  // The certificate must have an associated private key installed, and it must be a
  // private key that has been marked "exportable" when it was originally installed.
  if (!cert.hasPrivateKey()) {
    console.log('This certificate does not have a private key available.');
    return;
  }

  const privKey = new PrivateKey();
  try {
    cert.getPrivateKey(privKey);
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  const dkim = new Dkim();

  // Load the private key into the DKIM object:
  try {
    dkim.setDkimPrivateKey(privKey);
  } catch {
    console.log(dkim.lastErrorText);
    return;
  }

  // The private key has been loaded into the DKIM object.  See the other DKIM
  // examples for guidance on how to create a DKIM signature...
