type SecurityProtocolType

Member nameDescription
Ssl3Specifies the Secure Socket Layer (SSL) 3.0 security protocol.

SSL 3.0 has been superseded by the Transport Layer Security (TLS) protocol and is provided for backward compatibility only.

TlsSpecifies the Transport Layer Security (TLS) 1.0 security protocol.

TLS assumes that a connection-oriented protocol, typically TCP, is in use. The TLS protocol is defined in IETF RFC 2246.

This enumeration defines permissible values for the SecurityProtocol property and specifies the security protocols that are used by instances of the SslStream class.

The following code example demonstrates creating a TcpClient that uses the SslStream class to communicate with a server.

No code example is currently available or this language may not be supported.
