use chilkat();

$mime = new chilkat::CkMime();

$success = $mime->UnlockComponent("Anything for 30-day trial.");
if ($success == 0) {
    print $mime->lastErrorText() . "\r\n";
    exit;
}

#  Load the MIME
$success = $mime->LoadMimeFile("encrypted.mim");
if ($success == 0) {
    print $mime->lastErrorText() . "\r\n";
    exit;
}

#  Decrypt using a specific PFX file:
$pfxPassword = "myPassword";
$success = $mime->DecryptUsingPfxFile("c:/myPfxFiles/myCertAndPrivateKey.pfx",$pfxPassword);
if ($success == 0) {
    print $mime->lastErrorText() . "\r\n";
    exit;
}

#  Display the decrypted MIME:
print $mime->getMime() . "\r\n";

#  Note: The MIME to be decrypted should look something like this
#  when viewed in a text editor:
#  (Note that the Content-Type is application/x-pkcs7-mime)
#  
Content-Disposition: attachment; filename="smime.p7m"
Content-Transfer-Encoding: base64
Content-Type: application/x-pkcs7-mime;
 name="smime.p7m"
