!!! Overview
[{$pagename}] ([ECDH]) is an [anonymous] [Key-Exchange] [protocol] that allows two parties, each having an [Elliptic Curve] [Public Key]–[Private Key] pair, to establish a [Shared Secret] over an insecure channel.

This [Shared Secret] may be directly used as a key, or to derive another key. The key, or the derived key, can then be used to [encrypt] subsequent communications using a [Symmetric Key] [cipher]. 

[{$pagename}] is a variant of the [Diffie-Hellman key-exchange] [protocol] using [Elliptic Curve] [cryptography].
