UM1940
HAL HASH Generic Driver
DocID028236 Rev 2
275/1371
Return values
HAL: status
HAL_HASH_SHA1_Start_DMA
Function name
HAL_StatusTypeDef HAL_HASH_SHA1_Start_DMA
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)
Function description
Initializes the HASH peripheral in SHA1 mode then enables DMA
to control data transfer.
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
HAL_HASH_SHA1_Finish
Function name
HAL_StatusTypeDef HAL_HASH_SHA1_Finish
(HASH_HandleTypeDef * hhash, uint8_t * pOutBuffer, uint32_t
Timeout)
Function description
Returns the computed digest in SHA1 mode.
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
20 bytes.
Timeout: Timeout value
Return values
HAL: status
HAL_HASH_MD5_Start_DMA
Function name
HAL_StatusTypeDef HAL_HASH_MD5_Start_DMA
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)
Function description
Initializes the HASH peripheral in MD5 mode then enables DMA to
control data transfer.
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
HAL_HASH_MD5_Finish
Function name
HAL_StatusTypeDef HAL_HASH_MD5_Finish
(HASH_HandleTypeDef * hhash, uint8_t * pOutBuffer, uint32_t
Timeout)
