!!! Overview
[{$pagename}] is a relatively short-lived and often single-use [Symmetric Key] used for [encryption] of [messages] in one [communication] [session].

A [{$pagename}] should be strong enough to remain secure for the lifespan of the [session]. 

When [{$pagename}] are [exchanged|Key-Exchange], they are generally protected with [Asymmetric Keys] so that [{$pagename}]s remain [Confidential]. 

[{$pagename}] can be derived from a [Hash Function].

[Asymmetric Key Cryptography] is too slow for many purposes, and all secret key algorithms require that the key is securely distributed. By using an [Asymmetric Keys] to encrypt the [{$pagename}] for another, faster, [Symmetric Key] overall performance can be improved considerably.

!! Alternative Names for [{$pagename}]
The terms [MAC] [key], [{$pagename}], and often [Symmetric Key] are typically used interchangeably and refer to some form of [cryptographic] [keying material] established between the [client] and [server]. 

!! [EDirectory] ([NICI]) [{$pagename}]
[EDirectory] [{$pagename}]s  are [SASDFM keys]
