Functions
WOLFSSL_API int	wc_HashGetOID (enum wc_HashType hash_type)
	This function will return the OID for the wc_HashType provided.
WOLFSSL_API enum wc_HashType	wc_OidGetHash (int oid)
WOLFSSL_API enum wc_HashType	wc_HashTypeConvert (int hashType)
WOLFSSL_API int	wc_HashGetDigestSize (enum wc_HashType hash_type)
	This function returns the size of the digest (output) for a hash_type. The returns size is used to make sure the output buffer provided to wc_Hash is large enough.
WOLFSSL_API int	wc_HashGetBlockSize (enum wc_HashType hash_type)
WOLFSSL_API int	wc_Hash (enum wc_HashType hash_type, const byte *data, word32 data_len, byte *hash, word32 hash_len)
	This function performs a hash on the provided data buffer and returns it in the hash buffer provided.
WOLFSSL_API int	wc_HashInit_ex (wc_HashAlg *hash, enum wc_HashType type, void *heap, int devId)
WOLFSSL_API int	wc_HashInit (wc_HashAlg *hash, enum wc_HashType type)
WOLFSSL_API int	wc_HashUpdate (wc_HashAlg *hash, enum wc_HashType type, const byte *data, word32 dataSz)
WOLFSSL_API int	wc_HashFinal (wc_HashAlg *hash, enum wc_HashType type, byte *out)
WOLFSSL_API int	wc_HashFree (wc_HashAlg *hash, enum wc_HashType type)
WOLFSSL_API int	wc_HashSetFlags (wc_HashAlg *hash, enum wc_HashType type, word32 flags)
WOLFSSL_API int	wc_HashGetFlags (wc_HashAlg *hash, enum wc_HashType type, word32 *flags)

	Convenience function, handles all the hashing and places the result into hash.
WOLFSSL_API int	wc_Sha224Hash (const byte *, word32, byte *)
	Convenience function, handles all the hashing and places the result into hash.
