wolfSSL new wrappers for signature generation / verification and hashing

We’ve added some useful wrappers to the wolfSSL embedded SSL/TLS library for signature generation/verification and hashing. The signature wrappers support ECC and RSA. The hashing wrappers support MD5 and SHA, SHA256, SHA384 and SHA512.

Documentation for these new wrapper functions is in the wolfCrypt API Reference – Signature API and wolfCrypt Init and Cleanup.

New API functions:

#include <wolfssl/wolfcrypt/signature.h>
wc_SignatureGetSize
wc_SignatureVerify
wc_SignatureGenerate.

#include <wolfssl/wolfcrypt/hash.h>
wc_HashGetDigestSize
wc_Hash

An example for these new wrapper functions can be found here https://github.com/wolfSSL/wolfssl-examples/tree/master/signature. There is also an example for the wc_Hash function in wolfcrypt/src/signature.c.
