digital signature, use private key to encrypt MAC(message authorization
in TLS1.2, HAMC is used ,MAC will be encrypted with a key which is created
during the handshake.
is it necessary to use private key to encrypt the HAMC for non-repudiation?
Is the digital signature optional in TLS?
i think it is necessary to encrypt HMAC of every record,but I'm not sure
thanks in advance!
