Require SSL Server Certificate Domain Match

See more HTTP Examples

Demonstrates how to require that the SSL server certificate's domain matches the intended domain. Chilkat2 PHP

<?php

use Chilkat2\Http;

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

$http = new Http();

// Call SetSslCertRequirement to require that the SSL server certificate's domain
// matches only the domain we are intending to communicate with.

// In this example we will test with the URL https://wrong.host.badssl.com/
// which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

$http->SetSslCertRequirement('SAN', 'wrong.host.badssl.com');

// Also validate the server cert..
$http->RequireSslCertVerify = true;

// Try sending the request.  It should fail within the SSL/TLS handshake
// because the server's certificate does not match the domain "wrong.host.badssl.com"
try {
    $html = $http->QuickGetStr('https://wrong.host.badssl.com/');
    echo "Unexpected success.\n";
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
