This interface is implemented by all web-client credentials. The class NetworkCredential works with authentication schemes such as Basic and Digest authentication, NTLM, and Kerberos. If you need to implement a client authentication scheme not supported by .NET (such as SSL client certificates), you need to implement ICredentials and add a new instance of your implementation to your application's credential cache. For more information on using a credential cache, see CredentialCache.
