<?php

$cert = new COM("Chilkat_9_5_0.Cert");

//  LoadFromFile will load virtually any certificate format file.
//  It will auto-recognize the format and load appropiately.
//  In this case, load a PEM format certificate and convert to DER.
$success = $cert->LoadFromFile('/Users/chilkat/testData/pem/chilkat.pem');
if ($success != 1) {
    print $cert->LastErrorText . "\n";
    exit;
}

$success = $cert->ExportCertDerFile('chilkat.der');
if ($success != 1) {
    print $cert->LastErrorText . "\n";
    exit;
}

print 'Converted certificate from PEM to DER format.' . "\n";
