HAL_StatusTypeDef HAL_HASHEx_SHA224_Finish	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Returns the computed digest in SHA224.

Parameters:

hhash	pointer to a HASH_HandleTypeDef structure that contains the configuration information for HASH module
pOutBuffer	Pointer to the computed digest. Its size must be 28 bytes.
Timeout	Timeout value

Return values:

HAL_StatusTypeDef HAL_HASHEx_SHA224_Start_DMA	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size
	)

Initializes the HASH peripheral in SHA224 mode then enables DMA to control data transfer.

Use HAL_HASH_SHA224_Finish() to get the digest.

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.

Return values:

HAL_StatusTypeDef HAL_HASHEx_SHA256_Finish	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Returns the computed digest in SHA256.

Parameters:

hhash	pointer to a HASH_HandleTypeDef structure that contains the configuration information for HASH module
pOutBuffer	Pointer to the computed digest. Its size must be 32 bytes.
Timeout	Timeout value
