<?php

include("chilkat.php");

$success = false;

// On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
// having the specified CN.
$cert = new CkCert();
$success = $cert->LoadByCommonName('Certum CA');
if ($success == false) {
    print $cert->lastErrorText() . "\n";
    exit;
}

print $cert->subjectDN() . "\n";

// 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.
$cert2 = new CkCert();
$success = $cert2->LoadByCommonName('Chilkat Software, Inc.');
if ($success == false) {
    print $cert2->lastErrorText() . "\n";
