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
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.
