Detailed Description

SSL/TLS Handshake State

This is a data holder object for all state aggregated during the handshake, both on client and server side and across protocol versions. It does not implement any logic and offers no guarantees regarding state consistency and legal TLS state transitions.

TODO: currently it implements some logic for TLS 1.2, which should be removed TODO: investigate moving the handshake_io to the channel
