19 ##### HASH peripheral extended features #####
20 ===============================================================================
21 [..]
22 The SHA-224 and SHA-256 HASH and HMAC processing can be carried out exactly
23 the same way as for SHA-1 or MD-5 algorithms.
24 (#) Three modes are available.
25 (##) Polling mode: processing APIs are blocking functions
26 i.e. they process the data and wait till the digest computation is finished,
27 e.g. HAL_HASHEx_xxx_Start()
28 (##) Interrupt mode: processing APIs are not blocking functions
29 i.e. they process the data under interrupt,
30 e.g. HAL_HASHEx_xxx_Start_IT()
31 (##) DMA mode: processing APIs are not blocking functions and the CPU is
32 not used for data transfer i.e. the data transfer is ensured by DMA,
33 e.g. HAL_HASHEx_xxx_Start_DMA(). Note that in DMA mode, a call to
34 HAL_HASHEx_xxx_Finish() is then required to retrieve the digest.
35
36 (#)Multi-buffer processing is possible in polling and DMA mode.
37 (##) In polling mode, only multi-buffer HASH processing is possible.
38 API HAL_HASHEx_xxx_Accumulate() must be called for each input buffer, except for the last one.
39 User must resort to HAL_HASHEx_xxx_Start() to enter the last one and retrieve as
40 well the computed digest.
41
42 (##) In DMA mode, multi-buffer HASH and HMAC processing are possible.
43
44 (+++) HASH processing: once initialization is done, MDMAT bit must be set thru __HAL_HASH_SET_MDMAT() macro.
45 From that point, each buffer can be fed to the IP thru HAL_HASHEx_xxx_Start_DMA() API.
46 Before entering the last buffer, reset the MDMAT bit with __HAL_HASH_RESET_MDMAT()
47 macro then wrap-up the HASH processing in feeding the last input buffer thru the
48 same API HAL_HASHEx_xxx_Start_DMA(). The digest can then be retrieved with a call to
49 API HAL_HASHEx_xxx_Finish().
50
51 (+++) HMAC processing (MD-5, SHA-1, SHA-224 and SHA-256 must all resort to
52 extended functions): after initialization, the key and the first input buffer are entered
53 in the IP with the API HAL_HMACEx_xxx_Step1_2_DMA(). This carries out HMAC step 1 and
54 starts step 2.
55 The following buffers are next entered with the API HAL_HMACEx_xxx_Step2_DMA(). At this
56 point, the HMAC processing is still carrying out step 2.
57 Then, step 2 for the last input buffer and step 3 are carried out by a single call
58 to HAL_HMACEx_xxx_Step2_3_DMA().
59
60 The digest can finally be retrieved with a call to API HAL_HASH_xxx_Finish() for
61 MD-5 and SHA-1, to HAL_HASHEx_xxx_Finish() for SHA-224 and SHA-256.

596 [..] User must first start-up the multi-buffer DMA-based HMAC computation in
597 calling HAL_HMACEx_xxx_Step1_2_DMA(). This carries out HMAC step 1 and
598 intiates step 2 with the first input buffer.
599
600 [..] The following buffers are next fed to the IP with a call to the API
601 HAL_HMACEx_xxx_Step2_DMA(). There may be several consecutive calls
602 to this API.
603
604 [..] Multi-buffer DMA-based HMAC computation is wrapped up by a call to
605 HAL_HMACEx_xxx_Step2_3_DMA(). This finishes step 2 in feeding the last input
606 buffer to the IP then carries out step 3.
607
608 [..] Digest is retrieved by a call to HAL_HASH_xxx_Finish() for MD-5 or
609 SHA-1, to HAL_HASHEx_xxx_Finish() for SHA-224 or SHA-256.
610
