Documentation

Overview

Package message is used to create network messages for the purpose of confirming integrity and proof of work.

The main purpose of the message is the possibility of retransmission with verification by the network key.

MESSAGE FORMAT

P(HM) || HM || M
where
	HM = H(M)
	where
		P - proof of work
		H - hmac (auth-key)
		M - message bytes
