<?php

include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0

// On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
// having the specified CN.
$cert = new CkCert();

// Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
// When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
// You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
