Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate. React Native

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

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

  const sock = new Socket();

  // Set the certificate to be used for mutual TLS authentication
  // (i.e. sets the client-side certificate for two-way TLS authentication)
  try {
    sock.setSslClientCertPfx('/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx', 'pfxPassword');
  } catch {
    console.log(sock.lastErrorText);
    return;
  }

  // Note: The certificate used for the client-side of TLS mutual authentication
  // must have the associated private key available. (.pfx/.p12 files typically store both
  // the certificate and associated private key.)

  // Establish the connection using the socket object (with client certificate authentication).
  const bTls = true;
  const port = 443;
  const maxWaitMs = 5000;
  try {
    await sock.connectAsync('www.example.com', port, bTls, maxWaitMs);
  } catch {
    console.log(`Connect Failure Error Code: ${sock.connectFailReason}`);
    console.log(sock.lastErrorText);
    return;
  }

  // At this point, the Socket object is connected and authenticated using the client-side cert

  // ...
  // ...
