This package is designed as a replacement for crypto/sha256. For Intel CPUs it
has two flavors for AVX512 and AVX2 (AVX/SSE are also supported). For ARM CPUs
with the Cryptography Extensions, advantage is taken of the SHA2 instructions
resulting in a massive performance improvement.

This package uses Golang assembly. The AVX512 version is based on the Intel's
"multi-buffer crypto library for IPSec" whereas the other Intel implementations
are described in "Fast SHA-256 Implementations on Intel Architecture Processors"
by J. Guilford et al.

This package contains the source code needed for building packages that
reference the following Go import paths:
