PFX to PEM (Certificate and Private Key Files)

Export a certificate and private key from a PFX to a pair of PEM files.

<?php


$certStore = new COM("Chilkat.CertStore");

//  Load the PFX file into a certificate store object

$password = 'myPassword';
$success = $certStore->LoadPfxFile('chilkat.pfx',$password);
if ($success != true) {
    print $certStore->lastErrorText() . "\n";
    exit;
}

//  Find the cert to be exported by the subject:

// cert is a Chilkat.Cert
$cert = $certStore->FindCertBySubject('Chilkat Software, Inc.');
if (is_null($cert)) {
    print 'Certificate not found.' . "\n";
    exit;
}

//  Does this cert have a private key?
if ($cert->HasPrivateKey() == true) {

    //  Get the private key.

    // pvkey is a Chilkat.PrivateKey
    $pvkey = $cert->ExportPrivateKey();

    //   Export the private key to a PEM file:
    $success = $pvkey->SaveRsaPemFile('chilkat_pkey.pem');
    if ($success != true) {
        print $pvkey->lastErrorText() . "\n";
        exit;
    }

}

//  Save the cert to a PEM file:
$success = $cert->ExportCertPemFile('chilkat_cert.pem');
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}
