Detailed Description

Aggregate conventional handshake messages. This will update the given Transcript_Hash_State accordingly as individual messages are added to the aggregation.

Member Function Documentation

add()

Channel_Impl_13::AggregatedHandshakeMessages & Botan::TLS::Channel_Impl_13::AggregatedHandshakeMessages::add

(

Handshake_Message_13_Ref

message

)

Adds a single handshake message to the send buffer. Note that this updates the handshake transcript hash regardless of sending the message.

send()

std::vector< uint8_t > Botan::TLS::Channel_Impl_13::AggregatedMessages::send ( )

inherited

Send the messages aggregated in the message buffer. The buffer is returned if the sender needs to also handle it somehow. Most notable use: book keeping for a potential protocol downgrade in the client implementation.
