This document provides a way to authenticate one party of a Transport
Layer Security (TLS) communication to another using a certificate
after the session has been established. This allows both the client
and server to prove ownership of additional identities at any time
after the handshake has completed. This proof of authentication can
be exported and transmitted out of band from one party to be
validated by the other party.
