HAL HASH Generic Driver
DocID028236 Rev 2
273/1371
Return values
HAL: status
HAL_HASH_MD5_Accumulate
Function name
HAL_StatusTypeDef HAL_HASH_MD5_Accumulate
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)
Function description
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_HASH_SHA1_Accumulate
Function name
HAL_StatusTypeDef HAL_HASH_SHA1_Accumulate
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)
Function description
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.
Return values
HAL: status
Notes
Input buffer size in bytes must be a multiple of 4 otherwise the
digest computation is corrupted.
HAL_HMAC_SHA1_Start
Function name
HAL_StatusTypeDef HAL_HMAC_SHA1_Start
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size, uint8_t * pOutBuffer, uint32_t Timeout)
Function description
Initializes the HASH peripheral in HMAC 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.
pOutBuffer: Pointer to the computed digest. Its size must be
20 bytes.
Timeout: Timeout value
