Description

the client Finished message, when server didn't ask for client certificates, is completely deterministic, allowing it to be precomputed by the server, allowing the server to send NewSessionTicket messages without waiting for client's second flight.

related: #288

Contributor guide

Research direction
Investigate the TLS handshake flow to understand how to precompute the client Finished message and send NewSessionTicket earlier. See related issue #288.
