* @brief CRYP HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Cryptography (CRYP) peripheral:
* + Initialization and de-initialization functions
* + AES processing functions
* + DES processing functions
* + TDES processing functions
* + DMA callback functions
* + CRYP IRQ handler management
* + Peripheral State functions
*

==============================================================================
##### 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 __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 initilalized 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()
(+++) 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.
