PHP Extension

Convert Cert + Key to PEM and PFX

See more Certificates Examples

This example is based on the following question from a Chilkat customer:

We receive 2 files :

    MyCertificate.p7b
    MyCertificate-privatekey.pkey

We have to transform these certificate like this:

First convert it to PEM like this:

openssl pkcs7 -in MyCertificate.p7b -inform DER -out MyCertificate.pem -print_certs

Now we get MyCertificate.pem

Last step, we need to convert it to pfx file:

openssl pkcs12 -export -inkey moncertificat-privatekey.pkey  -in  moncertificat.pem -out moncertificat.pfx

Is there a way to make all these steps with Chilkat ?

I will be nice to include this directly in our software instead of askig the user to do it manualy.

<?php

include("chilkat.php");

$success = false;

$cert = new CkCert();
$privKey = new CkPrivateKey();

// Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile.
$success = $cert->LoadFromFile('qa_data/certs/sample_cert_a.cer');
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}

// Load the private key.
// (The various privKey methods that load from a file will automatically detect
// the format.  It doesn't actually matter if you try to load a non-PKCS8 format private key
// by calling LoadPkcs8EncryptedFile -- internally Chilkat will detect the format and will load
// based on what it finds.)
$success = $privKey->LoadPkcs8EncryptedFile('qa_data/certs/sample_key_a.pkcs8','password');
if ($success != true) {
    print $privKey->lastErrorText() . "\n";
    exit;
}

// Write the cert as PEM.
$success = $cert->ExportCertPemFile('qa_output/cert.pem');

// Or get the PEM string directly...
print $cert->exportCertPem() . "\n";

// Associate the private key with the cert object.
$success = $cert->SetPrivateKey($privKey);
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}

// Write the cert + private key to a .pfx file.
$success = $cert->ExportToPfxFile('qa_data/myPfx.pfx','password',true);
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}

print 'Success.' . "\n";
