Transport Layer Security

TLS is very similar to SSL in that it provides communications privacy, authentication, and message integrity by using a combination of public-key and symmetric encryption. In fact, TLS supports the option of reverting to SSL support, if need be. However, there are some important differences. TLS supports different encryption algorithms than SSL and is an Internet Engineering Task Force (IETF) draft standard. Many people view TLS as the likely successor to SSL in the long term.

Because TLS is designed to be a replacement for SSL, using either protocol should be transparent to the user. However, the software must be TLS- and SSL-aware.
