An SSL connection, such as that provided by <see cref="T:System.Net.Security.SslStream" />, should be used when communicating sensitive information between a client and a server. Using an <see cref="T:System.Net.Security.SslStream" /> helps to prevent anyone from reading and tampering with information while it is in transit on the network. </para><para>An <see cref="T:System.Net.Security.SslStream" /> instance transmits data using a stream that you supply when creating the <see cref="T:System.Net.Security.SslStream" />. When you supply this underlying stream, you have the option to specify whether closing the <see cref="T:System.Net.Security.SslStream" /> also closes the underlying stream. Typically, the <see cref="T:System.Net.Security.SslStream" /> class is used with the <see cref="T:System.Net.Sockets.TcpClient" /> and <see cref="T:System.Net.Sockets.TcpListener" /> classes. The <see cref="M:System.Net.Sockets.TcpClient.GetStream" /> method provides a <see cref="T:System.Net.Sockets.NetworkStream" /> suitable for use with the <see cref="T:System.Net.Security.SslStream" /> class.</para><para>After creating an <see cref="T:System.Net.Security.SslStream" />, the server and optionally, the client must be authenticated. The server must provide an X509 certificate that establishes proof of its identity and can request that the client also do so. Authentication must be performed before transmitting information using an <see cref="T:System.Net.Security.SslStream" />. Clients initiate authentication using the synchronous <see cref="Overload:System.Net.Security.SslStream.AuthenticateAsClient" /> methods, which block until the authentication completes, or the asynchronous <see cref="Overload:System.Net.Security.SslStream.BeginAuthenticateAsClient" /> methods, which do not block waiting for the authentication to complete. Servers initiate authentication using the synchronous <see cref="Overload:System.Net.Security.SslStream.AuthenticateAsServer" /> or asynchronous <see cref="Overload:System.Net.Security.SslStream.BeginAuthenticateAsServer" /> methods. Both client and server must initiate the authentication. </para><para>The authentication is handled by the Security Support Provider (SSPI) channel provider. The client is given an opportunity to control validation of the server's certificate by specifying a <see cref="T:System.Net.Security.RemoteCertificateValidationCallback" /> delegate when creating an <see cref="T:System.Net.Security.SslStream" />. The server can also control validation by supplying a <see cref="T:System.Net.Security.RemoteCertificateValidationCallback" /> delegate. The method referenced by the delegate includes the remote party's certificate and any errors SSPI encountered while validating the certificate. Note that if the server specifies a delegate, the delegate's method is invoked regardless of whether the server requested client authentication. If the server did not request client authentication, the server's delegate method receives a null certificate and an empty array of certificate errors. </para><para>If the server requires client authentication, the client must specify one or more certificates for authentication. If the client has more than one certificate, the client can provide a <see cref="T:System.Net.Security.LocalCertificateSelectionCallback" /> delegate to select the correct certificate for the server. The client's certificates must be located in the current user's "My" certificate store. Client authentication via certificates is not supported for the <see cref="F:System.Security.Authentication.SslProtocols.Ssl2" /> (SSL version 2) protocol.</para><para>If the authentication fails, you receive a <see cref="T:System.Security.Authentication.AuthenticationException" />, and the <see cref="T:System.Net.Security.SslStream" /> is no longer useable. You should close this object and remove all references to it so that it can be collected by the garbage collector. </para><para>When the authentication process, also known as the SSL handshake, succeeds, the identity of the server (and optionally, the client) is established and the <see cref="T:System.Net.Security.SslStream" /> can be used by the client and server to exchange messages. Before sending or receiving information, the client and server should check the security services and levels provided by the <see cref="T:System.Net.Security.SslStream" /> to determine whether the protocol, algorithms, and strengths selected meet their requirements for integrity and confidentiality. If the current settings are not sufficient, the stream should be closed. You can check the security services provided by the <see cref="T:System.Net.Security.SslStream" /> using the <see cref="P:System.Net.Security.SslStream.IsEncrypted" /> and <see cref="P:System.Net.Security.SslStream.IsSigned" /> properties.
