        return;

    //  Load the MIME
    success = mime.LoadMimeFile("encrypted.mim");
    if (success == false) {
        printf("%s\n",mime.lastErrorText());
        return;
    }

    //  Decrypt using a specific PFX file:
    const char * pfxPassword;
    pfxPassword = "myPassword";
    success = mime.DecryptUsingPfxFile("c:/myPfxFiles/myCertAndPrivateKey.pfx",pfxPassword);
    if (success == false) {
        printf("%s\n",mime.lastErrorText());
        return;
    }

    //  Display the decrypted MIME:
    printf("%s\n",mime.getMime());

    //  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"
