Russ Magee f5be3578a8 1/3 Updated Makefile to allow VENDOR flag (adds -vendor to version string)
2/3 Added vendor/ dir to lock down dependent pkg versions.
The author of git.schwanenlied.me/yawning/{chacha20,newhope,kyber}.git has copied
their repos to gitlab.com/yawning/ but some imports of chacha20 from newhope still
inconsistently refer to git.schwanenlied.me/, breaking build.
Licenses for chacha20 also changed from CC0 to AGPL, which may or may not be an
issue. Until the two aforementioned issues are resolved, locking to last-good
versions is probably the best way forward for now.

To build with vendored deps, use make VENDOR=1 clean all

XOR

XOR code engine in pure Go

more than 10GB/S per core

see: https://github.com/templexxx/xorsimd

Introduction:

  1. Use SIMD (SSE2 or AVX2) for speeding up
  2. ...

Installation

To get the package use the standard:

go get github.com/templexxx/xor

Documentation

See the associated GoDoc

Performance

Performance depends mainly on:

  1. SIMD extension
  2. unit size of worker
  3. hardware ( CPU RAM etc)

Example of performance on my MacBook 2014-mid(i5-4278U 2.6GHz 2 physical cores). The 16MB per shards.

speed = ( shards * size ) / cost
