Detailed Description

HMAC processing functions using interrupt mode.

 ===============================================================================
                 ##### Interrupt mode HMAC processing functions #####
 ===============================================================================
    [..]  This section provides functions allowing to calculate in interrupt mode
          the HMAC value using one of the following algorithms:
      (+) MD5
         (++) HAL_HMAC_MD5_Start_IT()
      (+) SHA1
         (++) HAL_HMAC_SHA1_Start_IT()

Function Documentation

HAL_StatusTypeDef HAL_HMAC_MD5_Start_IT	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer
	)

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

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.

Return values:

HAL

HAL_StatusTypeDef HAL_HMAC_SHA1_Start_IT	(	HASH_HandleTypeDef *	hhash,
		uint8_t *	pInBuffer,
		uint32_t	Size,
		uint8_t *	pOutBuffer
	)

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

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.

Return values:

HAL
