processing functions using polling mode

 ===============================================================================
              ##### HASH processing using polling mode functions#####
 ===============================================================================  
    [..]  This section provides functions allowing to calculate in polling mode
          the hash value using one of the following algorithms:
      (+) MD5
      (+) SHA1

HAL_StatusTypeDef HAL_HASH_MD5_Accumulate	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size
	)

Initializes the HASH peripheral in MD5 mode then writes the pInBuffer.

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 multiple of 64 bytes, appending the input buffer is possible. If the Size is not multiple of 64 bytes, the padding is managed by hardware and appending the input buffer is no more possible.

Return values:

HAL status

HAL_StatusTypeDef HAL_HASH_MD5_Start	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Initializes the HASH peripheral in MD5 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 multiple of 64 bytes, appending the input buffer is possible. If the Size is not multiple of 64 bytes, the padding is managed by hardware and appending the input buffer is no more possible.
pOutBuffer	Pointer to the computed digest. Its size must be 16 bytes.
Timeout	Timeout value

Return values:

HAL status

HAL_StatusTypeDef HAL_HASH_SHA1_Accumulate	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size
	)

Initializes the HASH peripheral in SHA1 mode then processes pInBuffer.

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.

Note:: Input buffer size in bytes must be a multiple of 4 otherwise the digest computation is corrupted.

Return values:

HAL status

HAL_StatusTypeDef HAL_HASH_SHA1_Start	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Initializes the HASH peripheral in SHA1 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 status
