Q.  How can I program TCP/IP security on Windows?

A.

If you just want to make a https connection you can use Wininet which is easy.
(Also works for ftp and gopher).

If you want to do IPSEC use WSASetSocketSecurity() on a socket.

If you want to do STARTTLS / SSL (other than https) use SChannel.
Or you can leave the Microsoft world and use OpenSSL.
