SSL/TLS Cipher Suites

A cipher suite combines four kinds of security features, and is given a name in the SSL protocol specification. Before data flows over a SSL connection, both ends attempt to negotiate a cipher suite. This lets them establish an appropriate quality of protection for their communications, within the constraints of the particular mechanism combinations which are available. The features associated with a cipher suite are:

A given implementation of SSL will support a particular set of cipher suites, and some subset of those will be enabled by default. Applications have a limited degree of control over the cipher suites that are used on their connections; they can enable or disable any of the supported cipher suites, but cannot change the cipher suites that are available.
