bool success = false;

Chilkat.Email email = new Chilkat.Email();

//  ...

//  ------------------------------------------------------------------------
//  The GetSignedByCert method is deprecated:

Chilkat.Cert certObj = email.GetSignedByCert();
if (email.LastMethodSuccess == false) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

//  ...

//  ------------------------------------------------------------------------
//  Do the equivalent using LastSignerCert.
//  Your application creates a new, empty Cert object which is passed 
//  in the last argument and filled upon success.

Chilkat.Cert certOut = new Chilkat.Cert();
