Overview

Package dpos Uses nacl's secret_box to encrypt a net.Conn. It is (meant to be) an implementation of the STS protocol. Note we do not (yet) assume that a remote peer's pubkey is known ahead of time, and thus we are technically still vulnerable to MITM. (TODO!) See docs/sts-final.pdf for more info
