##### How to use this driver #####
|
|
==============================================================================
|
|
[..]
|
|
The CRYP HAL driver can be used as follows:
|
|
|
|
(#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
|
|
(##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()
|
|
(##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT())
|
|
(+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
|
|
(+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
|
|
(+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
|
|
(##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA())
|
|
(+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
|
|
(+++) Configure and enable two DMA streams one for managing data transfer from
|
|
memory to peripheral (input stream) and another stream for managing data
|
|
transfer from peripheral to memory (output stream)
|
|
(+++) Associate the initialized DMA handle to the CRYP DMA handle
|
|
using __HAL_LINKDMA()
|
|
(+++) Configure the priority and enable the NVIC for the transfer complete
|
|
interrupt on the two DMA Streams. The output stream should have higher
|
|
priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
|
|
|
|
(#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
|
|
(##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
|
|
(##) The key size: 128, 192 and 256. This parameter is relevant only for AES
|
|
(##) The encryption/decryption key. It's size depends on the algorithm
|
|
used for encryption/decryption
|
|
(##) The initialization vector (counter). It is not used ECB mode.
|
|
|
|
(#)Three processing (encryption/decryption) functions are available:
|
|
(##) Polling mode: encryption and decryption APIs are blocking functions
|
|
i.e. they process the data and wait till the processing is finished,
|
|
e.g. HAL_CRYP_AESCBC_Encrypt()
|
|
(##) Interrupt mode: encryption and decryption APIs are not blocking functions
|
|
i.e. they process the data under interrupt,
|
|
e.g. HAL_CRYP_AESCBC_Encrypt_IT()
|
|
(##) DMA mode: encryption and decryption APIs are not blocking functions
|
|
i.e. the data transfer is ensured by DMA,
|
|
e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
|
|
|
|
(#)When the processing function is called at first time after HAL_CRYP_Init()
|
|
the CRYP peripheral is initialized and processes the buffer in input.
|
|
At second call, the processing function performs an append of the already
|
|
processed buffer.
|
|
When a new data block is to be processed, call HAL_CRYP_Init() then the
|
|
processing function.
|
|
|
|
(#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
