Cryptography API: Next Generation (CNG) http://msdn.microsoft.com/de-de/library/aa376210.aspx

CNG is supported beginning with Windows Server 2008 and Windows Vista. As this is WINAPI it should easily work with Delphi, and for .NET there exists wrapper classes.

another Option is to create a COM Wrapper for your C# code. (maybe a bit less secure)

I think you can solve this by using HttpListener in .net app(old post how to enable ssl), in such way you would get communication based on http protocol.
On top of that you can use additional layers:
a) OpenRasta, lightweight RESTful library
b) Self hosted WCF
