// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Mime mime = new Chilkat.Mime();

// Load the MIME
bool success = mime.LoadMimeFile("encryptedMime.txt");
if (success == false) {
    Debug.WriteLine(mime.LastErrorText);
    return;
}

// The AddPfxSourceFile and/or AddPfxSourceData
// methods may be called one or more times (one per PFX)
// to add sources from which the MIME component will
// search for certificates and private keys when decrypting.
string pfxPassword = "myPassword";
success = mime.AddPfxSourceFile("myCertAndPrivateKey.pfx",pfxPassword);
if (success == false) {

// Decrypt...

// Display the decrypted MIME:
