Configure a Socket for Server-Side TLS

See more Socket/SSL/TLS Examples

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

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.

<?php

use Chilkat2\Cert;
use Chilkat2\Socket;

$socket = new Socket();

// 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.
$pfxPassword = 'myPfxPassword';
$cert = new Cert();
try {
    $cert->LoadPfxFile('qa_data/server.pfx', $pfxPassword);

    // Configure this object for server-side TLS using the certificate.  The certificate must have
    // access to its corresponding private key.
    $socket->InitSslServer($cert);

    // Listen for connections.  Accepted connections will use TLS.
    $socket->BindAndListen(5000, 25);

    $connectedSock = new Socket();
    $socket->AcceptNext(20000, $connectedSock);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Accepted a TLS client connection.\n";
