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. Chilkat2 PHP

<?php

use Chilkat2\Socket;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$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 (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// 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).
$bTls = true;
$port = 443;
$maxWaitMs = 5000;
try {
    $sock->Connect('www.example.com', $port, $bTls, $maxWaitMs);
} catch (\Chilkat2\Exception $e) {
    echo 'Connect Failure Error Code: ', $sock->ConnectFailReason, "\n";
    echo $e->getMessage(), "\n";
    exit;
}

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