Functions
WOLFSSL_API int	wc_HmacSetKey (Hmac *, int type, const byte *key, word32 keySz)
	This function initializes an Hmac object, setting its encryption type, key and HMAC length.
WOLFSSL_API int	wc_HmacUpdate (Hmac *, const byte *, word32)
	This function updates the message to authenticate using HMAC. It should be called after the Hmac object has been initialized with wc_HmacSetKey. This function may be called multiple times to update the message to hash. After calling wc_HmacUpdate as desired, one should call wc_HmacFinal to obtain the final authenticated message tag.
WOLFSSL_API int	wc_HmacFinal (Hmac *, byte *)
	This function computes the final hash of an Hmac object's message.
WOLFSSL_API int	wc_HmacSizeByType (int type)
WOLFSSL_API int	wc_HmacInit (Hmac *hmac, void *heap, int devId)
WOLFSSL_API int	wc_HmacInit_Id (Hmac *hmac, byte *id, int len, void *heap, int devId)
WOLFSSL_API void	wc_HmacFree (Hmac *)
WOLFSSL_API int	wolfSSL_GetHmacMaxSize (void)
	This function returns the largest HMAC digest size available based on the configured cipher suites.
WOLFSSL_LOCAL int	_InitHmac (Hmac *hmac, int type, void *heap)
WOLFSSL_API int	wc_HKDF_Extract (int type, const byte *salt, word32 saltSz, const byte *inKey, word32 inKeySz, byte *out)
WOLFSSL_API int	wc_HKDF_Expand (int type, const byte *inKey, word32 inKeySz, const byte *info, word32 infoSz, byte *out, word32 outSz)
WOLFSSL_API int	wc_HKDF (int type, const byte *inKey, word32 inKeySz, const byte *salt, word32 saltSz, const byte *info, word32 infoSz, byte *out, word32 outSz)
	This function provides access to a HMAC Key Derivation Function (HKDF). It utilizes HMAC to convert inKey, with an optional salt and optional info into a derived key, which it stores in out. The hash type defaults to MD5 if 0 or NULL is given.
