Detailed Description

HASH extended processing functions using polling mode.

 ===============================================================================
               ##### Polling mode HASH extended processing functions #####
 ===============================================================================
    [..]  This section provides functions allowing to calculate in polling mode
          the hash value using one of the following algorithms:
      (+) SHA224
         (++) HAL_HASHEx_SHA224_Start()
         (++) HAL_HASHEx_SHA224_Accmlt()
         (++) HAL_HASHEx_SHA224_Accmlt_End()
      (+) SHA256
         (++) HAL_HASHEx_SHA256_Start()
         (++) HAL_HASHEx_SHA256_Accmlt()
         (++) HAL_HASHEx_SHA256_Accmlt_End()

    [..] For a single buffer to be hashed, user can resort to HAL_HASH_xxx_Start().

    [..]  In case of multi-buffer HASH processing (a single digest is computed while
          several buffers are fed to the Peripheral), the user can resort to successive calls
          to HAL_HASHEx_xxx_Accumulate() and wrap-up the digest computation by a call
          to HAL_HASHEx_xxx_Accumulate_End().

Function Documentation

HAL_StatusTypeDef HAL_HASHEx_SHA224_Accmlt	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size
	)

If not already done, initialize the HASH peripheral in SHA224 mode then processes pInBuffer.

Note:

Consecutive calls to HAL_HASHEx_SHA224_Accmlt() can be used to feed several input buffers back-to-back to the Peripheral that will yield a single HASH signature once all buffers have been entered. Wrap-up of input buffers feeding and retrieval of digest is done by a call to HAL_HASHEx_SHA224_Accmlt_End().

Field hhash->Phase of HASH handle is tested to check whether or not the Peripheral has already been initialized.

Digest is not retrieved by this API, user must resort to HAL_HASHEx_SHA224_Accmlt_End() to read it, feeding at the same time the last input buffer to the Peripheral.

The input buffer size (in bytes) must be a multiple of 4 otherwise, the HASH digest computation is corrupted. Only HAL_HASHEx_SHA224_Accmlt_End() is able to manage the ending buffer with a length in bytes not a multiple of 4.

Parameters:

hhash	HASH handle.
pInBuffer	pointer to the input buffer (buffer to be hashed).
Size	length of the input buffer in bytes, must be a multiple of 4.

Return values:

HAL
