NYX 0:85b3fd62ea1a 17 ==============================================================================
NYX 0:85b3fd62ea1a 18 ##### How to use this driver #####
NYX 0:85b3fd62ea1a 19 ==============================================================================
NYX 0:85b3fd62ea1a 20 [..]
NYX 0:85b3fd62ea1a 21 The HASH HAL driver can be used as follows:
NYX 0:85b3fd62ea1a 22 (#)Initialize the HASH low level resources by implementing the HAL_HASH_MspInit():
NYX 0:85b3fd62ea1a 23 (##) Enable the HASH interface clock using __HAL_RCC_HASH_CLK_ENABLE()
NYX 0:85b3fd62ea1a 24 (##) In case of using processing APIs based on interrupts (e.g. HAL_HMAC_SHA1_Start_IT())
NYX 0:85b3fd62ea1a 25 (+++) Configure the HASH interrupt priority using HAL_NVIC_SetPriority()
NYX 0:85b3fd62ea1a 26 (+++) Enable the HASH IRQ handler using HAL_NVIC_EnableIRQ()
NYX 0:85b3fd62ea1a 27 (+++) In HASH IRQ handler, call HAL_HASH_IRQHandler()
NYX 0:85b3fd62ea1a 28 (##) In case of using DMA to control data transfer (e.g. HAL_HMAC_SHA1_Start_DMA())
NYX 0:85b3fd62ea1a 29 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
NYX 0:85b3fd62ea1a 30 (+++) Configure and enable one DMA stream one for managing data transfer from
NYX 0:85b3fd62ea1a 31 memory to peripheral (input stream). Managing data transfer from
NYX 0:85b3fd62ea1a 32 peripheral to memory can be performed only using CPU
NYX 0:85b3fd62ea1a 33 (+++) Associate the initialized DMA handle to the HASH DMA handle
NYX 0:85b3fd62ea1a 34 using __HAL_LINKDMA()
NYX 0:85b3fd62ea1a 35 (+++) Configure the priority and enable the NVIC for the transfer complete
NYX 0:85b3fd62ea1a 36 interrupt on the DMA Stream using HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
NYX 0:85b3fd62ea1a 37 (#)Initialize the HASH HAL using HAL_HASH_Init(). This function configures mainly:
NYX 0:85b3fd62ea1a 38 (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit.
NYX 0:85b3fd62ea1a 39 (##) For HMAC, the encryption key.
NYX 0:85b3fd62ea1a 40 (##) For HMAC, the key size used for encryption.
NYX 0:85b3fd62ea1a 41 (#)Three processing functions are available:
NYX 0:85b3fd62ea1a 42 (##) Polling mode: processing APIs are blocking functions
NYX 0:85b3fd62ea1a 43 i.e. they process the data and wait till the digest computation is finished
NYX 0:85b3fd62ea1a 44 e.g. HAL_HASH_SHA1_Start()
NYX 0:85b3fd62ea1a 45 (##) Interrupt mode: encryption and decryption APIs are not blocking functions
NYX 0:85b3fd62ea1a 46 i.e. they process the data under interrupt
NYX 0:85b3fd62ea1a 47 e.g. HAL_HASH_SHA1_Start_IT()
NYX 0:85b3fd62ea1a 48 (##) DMA mode: processing APIs are not blocking functions and the CPU is
NYX 0:85b3fd62ea1a 49 not used for data transfer i.e. the data transfer is ensured by DMA
NYX 0:85b3fd62ea1a 50 e.g. HAL_HASH_SHA1_Start_DMA()
NYX 0:85b3fd62ea1a 51 (#)When the processing function is called at first time after HAL_HASH_Init()
NYX 0:85b3fd62ea1a 52 the HASH peripheral is initialized and processes the buffer in input.
NYX 0:85b3fd62ea1a 53 After that, the digest computation is started.
NYX 0:85b3fd62ea1a 54 When processing multi-buffer use the accumulate function to write the
NYX 0:85b3fd62ea1a 55 data in the peripheral without starting the digest computation. In last
NYX 0:85b3fd62ea1a 56 buffer use the start function to input the last buffer ans start the digest
NYX 0:85b3fd62ea1a 57 computation.
NYX 0:85b3fd62ea1a 58 (##) e.g. HAL_HASH_SHA1_Accumulate() : write 1st data buffer in the peripheral without starting the digest computation
NYX 0:85b3fd62ea1a 59 (##) write (n-1)th data buffer in the peripheral without starting the digest computation
NYX 0:85b3fd62ea1a 60 (##) HAL_HASH_SHA1_Start() : write (n)th data buffer in the peripheral and start the digest computation
NYX 0:85b3fd62ea1a 61 (#)In HMAC mode, there is no Accumulate API. Only Start API is available.
NYX 0:85b3fd62ea1a 62 (#)In case of using DMA, call the DMA start processing e.g. HAL_HASH_SHA1_Start_DMA().
NYX 0:85b3fd62ea1a 63 After that, call the finish function in order to get the digest value
NYX 0:85b3fd62ea1a 64 e.g. HAL_HASH_SHA1_Finish()
NYX 0:85b3fd62ea1a 65 (#)Call HAL_HASH_DeInit() to deinitialize the HASH peripheral.
