# Introduction
|
|||
|
|
|
|||
|
|
This library is an MIT-licensed compact HMAC-SHA-256 C++11 library
|
|||
|
|
designed for embedded systems. It is built following the JPL Power of
|
|||
|
|
Ten rules.
|
|||
|
|
|
|||
|
|
This library came about as a result of a need for a standalone SHA-256
|
|||
|
|
library for an embedded system. The original goal was to implement a
|
|||
|
|
wrapper around the code extracted from RFC 6234; instead a standalone
|
|||
|
|
implementation was decided on.

# Validation
|
|||
|
|
|
|||
|
|
- The behaviour of this package was cross-checked using the Go 1.5.1 linux/amd64 standard library\'s
|
|||
|
|
crypto/sha256 package.
