System.Net.Security Namespace

Provides network streams for secure communications between hosts.

Classes

AuthenticatedStream	Provides methods for passing credentials across a stream and requesting or performing authentication for client-server applications.
CipherSuitesPolicy	Specifies allowed cipher suites.
NegotiateAuthentication	Represents a stateful authentication exchange that uses the Negotiate, NTLM, or Kerberos security protocols to authenticate the client or server, in client-server communication.
NegotiateAuthenticationClientOptions	Represents a property bag for the client side of an authentication exchange.
NegotiateAuthenticationServerOptions	Represents a property bag for the server side of an authentication exchange.
NegotiateStream	Provides a stream that uses the Negotiate security protocol to authenticate the client, and optionally the server, in client-server communication.
SslCertificateTrust	Represents a trust policy for use with SSL/TLS connections.
SslClientAuthenticationOptions	Represents a client authentication property bag for the SslStream.
SslServerAuthenticationOptions	This struct represents a server authentication property bag for the SslStream.
SslStream	Provides a stream used for client-server communication that uses the Secure Socket Layer (SSL) security protocol to authenticate the server and optionally the client.
SslStreamCertificateContext	Represents a set of certificates used for building a certificate chain.

Structs

SslApplicationProtocol	Represents a value of TLS Application protocol.
SslClientHelloInfo	This struct contains information from received TLS Client Hello frame.

Enums

AuthenticationLevel	Specifies client requirements for authentication and impersonation when using the WebRequest class and derived classes to request a resource.
EncryptionPolicy	Specifies the encryption policy.
NegotiateAuthenticationStatusCode	Specifies the statuses for a single step of an authentication exchange.
ProtectionLevel	Indicates the security services requested for an authenticated stream.
SslPolicyErrors	Enumerates Secure Socket Layer (SSL) policy errors.
TlsCipherSuite	Represents cipher suite values for the TLS (formerly SSL) protocol.

Delegates

LocalCertificateSelectionCallback	Selects the local Secure Sockets Layer (SSL) certificate used for authentication.
RemoteCertificateValidationCallback	Verifies the remote Secure Sockets Layer (SSL) certificate used for authentication.
ServerCertificateSelectionCallback	Selects the server Secure Sockets Layer (SSL) certificate.
ServerOptionsSelectionCallback	Represents the asynchronous callback method that will select session properties based on the name requested by the client.
