Decrypt MIME with PFX

Demonstrates how to decrypt MIME using a PFX (containing a digital certificate with private key). The content-type of an encrypted MIME message looks like this:

Content-Type: application/x-pkcs7-mime;
	name="smime.p7m"

<?php

$mime = new COM("Chilkat.Mime");

$success = $mime->UnlockComponent('Anything for 30-day trial');
if ($success == false) {
    print 'Failed to unlock component' . "\n";
    exit;
}

$success = $mime->LoadMimeFile('encryptedEmail.eml');
if ($success != true) {
    print $mime->lastErrorText() . "\n";
    exit;
}

$certStore = new COM("Chilkat.CertStore");
$success = $certStore->LoadPfxFile('myPfx.pfx','myPfxPassword');
if ($success != true) {
    print $certStore->lastErrorText() . "\n";
    exit;
}

//  Find the certificate by email address.  There are many
//  ways to find certificates within a Chilkat certificate store
//  object...

// cert is a Chilkat.Cert
$cert = $certStore->FindCertBySubjectE('support@chilkatsoft.com');
if (is_null($cert)) {
    print $certStore->lastErrorText() . "\n";
    exit;
}

// privKey is a Chilkat.PrivateKey
$privKey = $cert->ExportPrivateKey();
if (is_null($privKey)) {
    print $cert->lastErrorText() . "\n";

    exit;
}

$success = $mime->Decrypt2($cert,$privKey);
if ($success != true) {
    print $mime->lastErrorText() . "\n";
    exit;
}

//  Show the decrypted MIME:
print $mime->getMime() . "\n";
