Windows Authentication / Encryption in WCF With NetTcpBinding

Question

I'm trying to understand how windows authentication / encryption works with the NetTcpBinding in WCF. I need to know exactly what encryption algorithm is used to encrypt the data going across the wire (and some documentation to prove it). Will windows authentication / encryption still work if the client and or host is not on a domain?

Answer 1

The netTcpBinding using Windows Credentials requires the caller and the service to be on the same domain - or at least on mutually trusting domains. Otherwise, the server won't be able to verify the Windows credentials and will refuse the service call.

As for encryption : you can even pick and choose which one you'd like ! :-) TripleDES, AES - you name it, with varying key lengths, too.

See the Fundamentals of WCF Security article - it talks about all aspects of security and encryption; also see the MSDN Docs on Securing Services which goes into some more detail; a good overview can be found here showing the properties of the basicHttp transport security element.
