ST STM32F2

HAL HASH Generic Driver
UM1940
276/1371
DocID028236 Rev 2
Function description
Returns the computed digest in MD5 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
16 bytes.
Timeout: Timeout value
Return values
HAL: status
HAL_HMAC_SHA1_Start_DMA
Function name
HAL_StatusTypeDef HAL_HMAC_SHA1_Start_DMA
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)
Function description
Initializes the HASH peripheral in HMAC 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_HMAC_MD5_Start_DMA
Function name
HAL_StatusTypeDef HAL_HMAC_MD5_Start_DMA
(HASH_HandleTypeDef * hhash, uint8_t * pInBuffer, uint32_t
Size)

HAL: status
HAL_HASH_IRQHandler
Function name
void HAL_HASH_IRQHandler (HASH_HandleTypeDef * hhash)
Function description
This function handles HASH interrupt request.
Parameters
hhash: pointer to a HASH_HandleTypeDef structure that
contains the configuration information for HASH module
Return values
None:
HAL_HASH_GetState
