Detailed Description

template<Connection_Side whoami, typename Outbound_Message_T, typename Inbound_Message_T, typename Inbound_Post_Handshake_Message_T>
class Botan::TLS::Handshake_State_13< whoami, Outbound_Message_T, Inbound_Message_T, Inbound_Post_Handshake_Message_T >

Place to store TLS handshake messages

This class is used to keep all handshake messages that have been received from and sent to the peer as part of the TLS 1.3 handshake. Getters are provided for all message types. Specializations for the client and server side provide specific setters in the form of sent and received that only allow those types of handshake messages that are sensible for the respective connection side.

The handshake state machine as described in RFC 8446 Appendix A is NOT validated here.
