conn

Documentation

Overview

Package conn makes it possible to hide the structure of the true message by encrypting and adding random bytes.

NETWORK MESSAGE FORMAT

E( LEM || LV || H(LEM||LV) || H(EM||V) ) || EM || V
where
	LEM = L(EM)
	LV  = L(V)
	EM  = E(M)
	where
		E - encrypt (cipher-key)
		H - hmac (auth-key)
		L - length
		M - message bytes
		V - void bytes
