[[wikipedia:Transport Layer Security]] [[cryptographic protocol]] successor to [[SSL]] (deprecated since 2011).

{{Draft}}
  
Once the client and server have agreed to use TLS, they negotiate a stateful connection by using a handshaking procedure. The protocols use a handshake with an [[asymmetric cipher]] to establish not only cipher settings but also a session-specific shared key with which further communication is encrypted using a [[symmetric cipher]].
