brontide: reduce memory allocs by using static buf for next header+msg
In this commit, we reduce the total number of allocations that a
brontide session will incur over its lifetime. Profiling on one of my
nodes showed that we were generating a lot of garbage due to
re-creating a 65KB buffer to read the next message each time the
ReadMessage method was called.

To reduce the total number of memory allocations, we’ll now simply
re-use a buffer for both the cipher text header, and the cipher text
itself.

brontide

Build Status MIT licensed GoDoc

The brontide package implements a secure crypto messaging protocol based off of the Noise Protocol Framework. The package exposes the raw state machine that handles the handshake and subsequent message encryption/decryption scheme. Additionally, the package exposes a net.Conn and a net.Listener interface implementation which allows the encrypted transport to be seamlessly integrated into a codebase.

The secure messaging scheme implemented within this package is described in detail in BOLT #8 of the Lightning Network specifications.

This package has intentionally been designed so it can be used as a standalone package for any projects needing secure encrypted+authenticated communications between network enabled programs.
