digital signature, use private key to encrypt MAC(message authorization
code) ,

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
about that.

thanks in advance!
