It allow to init, update and sign hash. Hash algorithm depends on SignatureAlgorithm. select (SignatureAlgorithm) { case anonymous: struct { }; case rsa: digitally-signed struct { opaque md5_hash[16]; opaque sha_hash[20]; }; case dsa: digitally-signed struct { opaque sha_hash[20]; }; } Signature; Digital signing description see in TLS spec., 4.7.
