bogdanm	0:9b334a45a8ff	19	##### How to use this driver #####
bogdanm	0:9b334a45a8ff	20	==============================================================================
bogdanm	0:9b334a45a8ff	21	[..]
bogdanm	0:9b334a45a8ff	22	The CRYP HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	23
bogdanm	0:9b334a45a8ff	24	(#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
bogdanm	0:9b334a45a8ff	25	(##) Enable the CRYP interface clock using __HAL_RCC_AES_CLK_ENABLE()
bogdanm	0:9b334a45a8ff	26	(##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT())
bogdanm	0:9b334a45a8ff	27	(+) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
bogdanm	0:9b334a45a8ff	28	(+) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
bogdanm	0:9b334a45a8ff	29	(+) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
bogdanm	0:9b334a45a8ff	30	(##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA())
bogdanm	0:9b334a45a8ff	31	(+) Enable the DMA1 interface clock using
bogdanm	0:9b334a45a8ff	32	(++) __HAL_RCC_DMA1_CLK_ENABLE()
bogdanm	0:9b334a45a8ff	33	(+) Configure and enable two DMA Channels one for managing data transfer from
bogdanm	0:9b334a45a8ff	34	memory to peripheral (input channel) and another channel for managing data
bogdanm	0:9b334a45a8ff	35	transfer from peripheral to memory (output channel)
bogdanm	0:9b334a45a8ff	36	(+) Associate the initialized DMA handle to the CRYP DMA handle
bogdanm	0:9b334a45a8ff	37	using __HAL_LINKDMA()
bogdanm	0:9b334a45a8ff	38	(+) Configure the priority and enable the NVIC for the transfer complete
bogdanm	0:9b334a45a8ff	39	interrupt on the two DMA Streams. The output stream should have higher
bogdanm	0:9b334a45a8ff	40	priority than the input stream.
bogdanm	0:9b334a45a8ff	41	(++) HAL_NVIC_SetPriority()
bogdanm	0:9b334a45a8ff	42	(++) HAL_NVIC_EnableIRQ()
bogdanm	0:9b334a45a8ff	43
bogdanm	0:9b334a45a8ff	44	(#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
bogdanm	0:9b334a45a8ff	45	(##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
bogdanm	0:9b334a45a8ff	46	(##) The encryption/decryption key.
bogdanm	0:9b334a45a8ff	47	(##) The initialization vector (counter). It is not used ECB mode.
bogdanm	0:9b334a45a8ff	48
bogdanm	0:9b334a45a8ff	49	(#)Three processing (encryption/decryption) functions are available:
bogdanm	0:9b334a45a8ff	50	(##) Polling mode: encryption and decryption APIs are blocking functions
bogdanm	0:9b334a45a8ff	51	i.e. they process the data and wait till the processing is finished
bogdanm	0:9b334a45a8ff	52	e.g. HAL_CRYP_AESCBC_Encrypt()
bogdanm	0:9b334a45a8ff	53	(##) Interrupt mode: encryption and decryption APIs are not blocking functions
bogdanm	0:9b334a45a8ff	54	i.e. they process the data under interrupt
bogdanm	0:9b334a45a8ff	55	e.g. HAL_CRYP_AESCBC_Encrypt_IT()
bogdanm	0:9b334a45a8ff	56	(##) DMA mode: encryption and decryption APIs are not blocking functions
bogdanm	0:9b334a45a8ff	57	i.e. the data transfer is ensured by DMA
bogdanm	0:9b334a45a8ff	58	e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
bogdanm	0:9b334a45a8ff	59
bogdanm	0:9b334a45a8ff	60	(#)When the processing function is called for the first time after HAL_CRYP_Init()
bogdanm	0:9b334a45a8ff	61	the CRYP peripheral is initialized and processes the buffer in input.
bogdanm	0:9b334a45a8ff	62	At second call, the processing function performs an append of the already
bogdanm	0:9b334a45a8ff	63	processed buffer.
bogdanm	0:9b334a45a8ff	64	When a new data block is to be processed, call HAL_CRYP_Init() then the
bogdanm	0:9b334a45a8ff	65	processing function.
bogdanm	0:9b334a45a8ff	66
bogdanm	0:9b334a45a8ff	67	(#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
