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

include("chilkat.php");

$success = false;

$socket = new CkSocket();

//  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 CkCert();
$success = $cert->LoadPfxFile('qa_data/server.pfx',$pfxPassword);
if ($success == false) {
    print $cert->lastErrorText() . "\n";
    exit;
}

//  Configure this object for server-side TLS using the certificate.  The certificate must have
//  access to its corresponding private key.
$success = $socket->InitSslServer($cert);
if ($success == false) {
    print $socket->lastErrorText() . "\n";
    exit;
}

//  Listen for connections.  Accepted connections will use TLS.
$success = $socket->BindAndListen(5000,25);
if ($success == false) {
    print $socket->lastErrorText() . "\n";
    exit;
}

$connectedSock = new CkSocket();
$success = $socket->AcceptNext(20000,$connectedSock);
if ($success == false) {
    print $socket->lastErrorText() . "\n";
    exit;
}

print 'Accepted a TLS client connection.' . "\n";
