Compability when using .NET security API to sign docs for GNUPG

There is a wrapper (GnuPGWrapper v1.0) for GNUPG in order to encrypt/decrypt
by using GNUPG executables under the .NET framework.

My question is: Is it possible to encrypt the document by using the .NET
1.1 Framework security APIs and decrypt the document by original GNUPG in
other end?

If there is no way to do it or it would require too much effort then I would
use the windows binary and call it from the GnuPGWrapper and do extra
stability testing of calling a non-manage code in ASP.NET.

Anyhow, help on this concern is highly appreciated. Also if you have some
code example how to do it within .NET framework that would make my day.

Thanks in advanced...
