TLS supports many different methods for exchanging keys, encrypting data, and authenticating message integrity (see § Algorithm below).

As a result, secure configuration of TLS involves many configurable parameters, and not all choices provide all of the privacy-related properties described in the list above (see the § Key exchange (authentication), § Cipher security, and § Data integrity tables).

The TLS protocol comprises two layers: the TLS record and the TLS handshake protocols.

which would imply that it is above the transport layer.During this handshake, the client and server agree on various parameters used to establish the connection's security: This concludes the handshake and begins the secured connection, which is encrypted and decrypted with the session key until the connection closes.If any one of the above steps fails, then the TLS handshake fails and the connection is not created.It serves encryption to higher layers, which is normally the function of the presentation layer.

However, applications generally use TLS as if it were a transport layer, Early research efforts towards transport layer security included the Secure Network Programming (SNP) application programming interface (API), which in 1993 explored the approach of having a secure transport layer API closely resembling Berkeley sockets, to facilitate retrofitting pre-existing network applications with security measures.

Symantec currently accounts for just under a third of all certificates and 44% of the valid certificates used by the 1 million busiest websites, as counted by Netcraft.
