Chilkat2 PHP

<?php

use Chilkat2\Cert;

// On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
// having the specified CN.
$cert = new Cert();
try {
    $cert->LoadByCommonName('Certum CA');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $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 Cert();
try {
    $cert2->LoadByCommonName('Chilkat Software, Inc.');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $cert2->SubjectDN, "\n";
$hasPrivKey = $cert2->HasPrivateKey();
echo 'Has private key: ', ($hasPrivKey ? 'true' : 'false'), "\n";

echo "Success.\n";
