HAL_StatusTypeDef HAL_HMACEx_SHA224_Start	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Initializes the HASH peripheral in HMAC SHA224 mode then processes pInBuffer.

The digest is available in pOutBuffer.

Parameters:

hhash	pointer to a HASH_HandleTypeDef structure that contains the configuration information for HASH module
pInBuffer	Pointer to the input buffer (buffer to be hashed).
Size	Length of the input buffer in bytes. If the Size is not multiple of 64 bytes, the padding is managed by hardware.
pOutBuffer	Pointer to the computed digest. Its size must be 20 bytes.
Timeout	Timeout value

Return values:

HAL
