'  Display the decrypted MIME:

'  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;
