Subject Alternative Name

See more Certificates Examples

Demonstrates the usage of the SubjectAlternativeName property to get the certificate SAN (subject alternative name) as XML. Chilkat2 PHP

<?php

use Chilkat2\Cert;
use Chilkat2\Xml;

// Note: Not all certificates contain a Subject Alternative Name.
// If it does not, the SubjectAlternativeName property will contain the empty string.

$cert = new Cert();

try {
    $cert->LoadFromFile('qa_data/certs/testIcpBrasil.cer');
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

$subjectAltNameXml = $cert->SubjectAlternativeName;

echo $subjectAltNameXml, "\n";

// Here's a sample of the subjectAltNameXml:

/*
 * <?xml version="1.0" encoding="utf-8"?>
 * <SubjectAltName>
 *     <name type="oid" oid="2.16.76.1.3.4">...</name>
 *     <name type="oid" oid="2.16.76.1.3.2">...</name>
 *     <name type="oid" oid="2.16.76.1.3.3">...</name>
 *     <name type="oid" oid="2.16.76.1.3.7">...</name>
 *     <rfc822Name>...</rfc822Name>
 * </SubjectAltName>
 */

// The XML can be parsed like this:

$xml = new Xml();

$xml->LoadXml($subjectAltNameXml);

$oid = '';
$name = '';

$i = 0;
$count_i = $xml->NumChildrenHavingTag('name');
while ($i < $count_i) {
    $xml->I = $i;
    $oid = $xml->ChilkatPath('name[i]|(oid)');
    $name = $xml->GetChildContent('name[i]');
    $i = $i + 1;
}

$rfc822Name = $xml->GetChildContent('rfc822Name');
