processing functions using interrupt mode.

 ===============================================================================
              ##### HASH processing using interrupt functions #####
 ===============================================================================  
    [..]  This section provides functions allowing to calculate in interrupt mode
          the hash value using one of the following algorithms:
      (+) SHA224
      (+) SHA256

void HAL_HASHEx_IRQHandler ( HASH_HandleTypeDef * hhash )

This function handles HASH interrupt request.

Parameters:

hhash pointer to a HASH_HandleTypeDef structure that contains the configuration information for HASH module

Return values:

None

HAL_StatusTypeDef HAL_HASHEx_SHA224_Start_IT	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer
	)

Initializes the HASH peripheral in 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.

Return values:

HAL status
