  ==============================================================================
                     ##### 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.
