HAL_HASH_busy

#define HAL_HASH_busy

(

)

(hwp_aes_acc->STATUS & AES_ACC_STATUS_BUSY)

Test whether AES hardware block is busy.

Function Documentation

HAL_HASH_init()

int HAL_HASH_init	(	uint32_t *	iv,
		uint8_t	algo,
		uint32_t	length
	)

Initialize AES Hash hardware block.

Parameters

iv	initial vector, must be 32bit aligned, if NULL, use algorithm default initial vector.
algo	hash algorithm
length	finished length

Return values

0	if successful, otherwise -1

HAL_HASH_reset()

int HAL_HASH_reset

(

void

)

Reset AES HASH hardware block.

Return values

0	if successful, otherwise -1

HAL_HASH_result()

void HAL_HASH_result

(

uint8_t *

out_data

)

Get hash result.

Parameters

out_data

output data, Size of out_data depends on hash algorithm

Note

SHA224 result is 28 bytes, but internal need 32 byte, please allocate 32 bytes for usage.

HAL_HASH_run()

HAL_StatusTypeDef HAL_HASH_run	(	uint8_t *	in_data,
		int	size,
		int	final
	)

run Hash hardware

Parameters

in_data	input data, input data could not in ITCM or Retention memory
size	length of input data in bytes.
final	Last block

Return values

HAL_OK

if successful, otherwise HAL_ERROR

HAL_HASH_run_IT()

HAL_StatusTypeDef HAL_HASH_run_IT	(	uint8_t *	in_data,
		int	size,
		int	final
	)

run Hash hardware, return immediately, generate AES HASH interrupt when done.

Parameters

in_data	input data, input data could not in ITCM or Retention memory
size	length of input data in bytes.
final	Last block

Return values

HAL_OK

if successful, otherwise HAL_ERROR
