Data Fields
struct GNUNET_CRYPTO_SignaturePurpose	purpose
	Purpose must be GNUNET_SIGNATURE_PURPOSE_COMMUNICATOR_TCP_HANDSHAKE_ACK.
struct GNUNET_PeerIdentity	sender
	Identity of the inititor of the TCP connection (TCP client).
struct GNUNET_PeerIdentity	receiver
	Presumed identity of the target of the TCP connection (TCP server)
struct GNUNET_TIME_AbsoluteNBO	monotonic_time
	Monotonic time of sender, to possibly help detect replay attacks (if receiver persists times by sender).
struct GNUNET_CRYPTO_ChallengeNonceP	challenge
	Challenge value used to protect against replay attack, if there is no stored monotonic time value.
