System.ServiceModel 4.0.0.0 System.Object Digest authentication verifies that both parties to a communication know a shared secret (a password). Authentication is done without sending the password in the clear. Digest authentication is based on a challenge-response paradigm. The Digest scheme challenges using a nonce ("number used once") value. The response must contain a checksum of the user name, the password, the nonce value, the HTTP method, and the requested URI.

Used for digest authentication of HTTP clients.

Property 4.0.0.0 System.Net.NetworkCredential To be added. If not specified, the default thread credential will be used.
