Elliptic Curve Cryptography (ECC) Brainpool curves were an option for
authentication and key exchange in the Transport Layer Security (TLS)
protocol version 1.2 but were deprecated by the IETF for use with TLS
version 1.3 because they had little usage. However, these curves have
not been shown to have significant cryptographical weaknesses, and
there is some interest in using several of these curves in TLS 1.3.

This document provides the necessary protocol mechanisms for using
ECC Brainpool curves in TLS 1.3. This approach is not endorsed by the
IETF.
