Detailed Description

Handshake IO Interface

This interface abstracts over stream and datagram processing of handshake messages. It receives individual records from the channel via add_record and provides a sending interface via a callback function provided by the channel.

Handshake message headers are parsed and removed in get_next_record. The result is provided back to the channel via Handshake_State::get_next_handshake_msg.

send is used by individual handshake message implementations, which send themselves, as well as both client and server to dispatch CCS messaged (and Hello_Verify_Request in the server case). Before calling the writer_fn, format is called to add the handshake message header (except for CCS).

The buffer returned by send is used to update the transcript record hash (where desired).
