21 The HASH HAL driver can be used as follows:
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
22 (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
23 (##) Enable the HASH interface clock using __HAL_RCC_HASH_CLK_ENABLE()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
24 (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT())
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
25 (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
26 (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
27 (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
28 (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA())
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
29 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:

30 (+++) Configure and enable one DMA stream one for managing data transfer from
5f11787b4f42 include in ostc4 repository
heinrichsweikamp

31 memory to peripheral (input stream). Managing data transfer from
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
32 peripheral to memory can be performed only using CPU
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
33 (+++) Associate the initialized DMA handle to the HASH DMA handle
5f11787b4f42 include in ostc4 repository

34 using __HAL_LINKDMA()
5f11787b4f42 include in ostc4 repository

36 interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
37 (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
38 (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
39 (##) For HMAC, the encryption key.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
40 (##) For HMAC, the key size used for encryption.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
41 (#)Three processing functions are available:
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
42 (##) Polling mode: processing APIs are blocking functions
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
43 i.e. they process the data and wait till the digest computation is finished
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
44 e.g. HAL_HASH_SHA1_Start()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
45 (##) Interrupt mode: encryption and decryption APIs are not blocking functions
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
46 i.e. they process the data under interrupt
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
47 e.g. HAL_HASH_SHA1_Start_IT()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:

48 (##) DMA mode: processing APIs are not blocking functions and the CPU is
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
49 not used for data transfer i.e. the data transfer is ensured by DMA
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
50 e.g. HAL_HASH_SHA1_Start_DMA()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:

51 (#)When the processing function is called at first time after HAL_HASH_Init()
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
52 the HASH peripheral is initialized and processes the buffer in input.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
53 After that, the digest computation is started.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
54 When processing multi-buffer use the accumulate function to write the
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
55 data in the peripheral without starting the digest computation. In last
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
56 buffer use the start function to input the last buffer ans start the digest
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
57 computation.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
58 (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
59 (##) write (n-1)th data buffer in the peripheral without starting the digest computation

5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:

61 (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
62 (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA().
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
63 After that, call the finish function in order to get the digest value
5f11787b4f42 include in ostc4 repository
heinrichsweikamp
parents:
diff changeset
64 e.g. HAL_HASH_SHA1_Finish()
5f11787b4f42 include in ostc4 repository
