use chilkat();


$mime = new chilkat::CkMime();

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

#  Build a simple MIME message to be encrypted:
$mime->AddHeaderField("Content-Type","text/plain");
$mime->AddHeaderField("abc","123");
$mime->SetBody("This is a test");

#  A digital certificate is required to create PKCS7 encrypted MIME.
#  It can come from a variety of sources: .cer file, .pfx file, PEM files,
#  an in-memory representation, or directly from a Windows
#  registry-based certificate store.

#  This example will load a certificate object from a .cer file.
#  Note: Only the public-key is required to encrypt.  (Decryption
#  requires a private key.)

$cert = new chilkat::CkCert();
$success = $cert->LoadFromFile("myCert.cer");
if ($success == 0) {
    print $cert->lastErrorText() . "\r\n";
    exit;
}

#  Encrypt the MIME:
$success = $mime->Encrypt($cert);
if ($success == 0) {
    print $mime->lastErrorText() . "\r\n";
    exit;
}

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

#  The resulting S/MIME looks something like this:
#  
abc: 123
Content-Disposition: attachment; filename="smime.p7m"
Content-Transfer-Encoding: base64
Content-Type: application/x-pkcs7-mime;
 name="smime.p7m"
