DESCRIPTION
This library provides the interface to SHA-256 secure hash algorithms.
SHA-256 performs processing on message blocks to produce a final hash digest
output. It can be used to hash a message, M, having a length of L bits,
where 0 <= L < 2^64.
Note that in some cases, hardware acceleration may be enabled, depending
on the specific device platform.

* SHA256 Build Options:

* WOLFSSL_SHA256_BY_SPEC: Uses the Ch/Maj based on SHA256 specification

optimize and recognize as SHA256 (default OFF)
