Detailed Description

HMAC processing functions using polling mode.

 ===============================================================================
                 ##### Polling mode HMAC processing functions #####
 ===============================================================================
    [..]  This section provides functions allowing to calculate in polling mode
          the HMAC value using one of the following algorithms:
      (+) MD5
         (++) HAL_HMAC_MD5_Start()
      (+) SHA1
         (++) HAL_HMAC_SHA1_Start()

Function Documentation

HAL_HMAC_MD5_Start()

HAL_StatusTypeDef HAL_HMAC_MD5_Start	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Initialize the HASH peripheral in HMAC MD5 mode, next process pInBuffer then read the computed digest.

Note

Digest is available in pOutBuffer.

Same key is used for the inner and the outer hash functions; pointer to key and key size are respectively stored in hhash->Init.pKey and hhash->Init.KeySize.

Parameters

hhash	HASH handle.
pInBuffer	pointer to the input buffer (buffer to be hashed).
Size	length of the input buffer in bytes.
pOutBuffer	pointer to the computed digest. Digest size is 16 bytes.
Timeout	Timeout value.

Return values

  return HMAC_Start(hhash, pInBuffer, Size, pOutBuffer, Timeout, HASH_ALGOSELECTION_MD5);

HAL_HMAC_SHA1_Start()

HAL_StatusTypeDef HAL_HMAC_SHA1_Start	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer,
		uint32_t	Timeout
	)

Initialize the HASH peripheral in HMAC SHA1 mode, next process pInBuffer then read the computed digest.

Note

Digest is available in pOutBuffer.

Same key is used for the inner and the outer hash functions; pointer to key and key size are respectively stored in hhash->Init.pKey and hhash->Init.KeySize.

Parameters

hhash	HASH handle.
pInBuffer	pointer to the input buffer (buffer to be hashed).
Size	length of the input buffer in bytes.
pOutBuffer	pointer to the computed digest. Digest size is 20 bytes.
Timeout	Timeout value.
