This next question asks about the handshake protocol in TOR.
In the handshake protocol, which is based on the Diffie-Hellman key agreement,
Alice sends Bob g^x encrypted with Bob's public key
and Bob responds with g^y and the hash of K plus the handshake
where K is g^xy, which is the shared symmetric key.
The question is, why does the response include the hash of K and the handshake.
Check all that apply.
