  * @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 __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.

    [..]  This section provides functions allowing to:
      (+) Encrypt plaintext using TDES based on ECB or CBC chaining modes
      (+) Decrypt cyphertext using TDES based on ECB or CBC chaining modes
    [..]  Three processing functions are available:
      (+) Polling mode
      (+) Interrupt mode
      (+) DMA mode

              ##### Initialization and deinitialization functions #####
  ==============================================================================
    [..]  This section provides functions allowing to:
      (+) Initialize the CRYP according to the specified parameters 
          in the CRYP_InitTypeDef and creates the associated handle
      (+) DeInitialize the CRYP peripheral
      (+) Initialize the CRYP MSP (MCU Specific Package)
      (+) De-Initialize the CRYP MSP
      
    [..]
    (@) Specific care must be taken to format the key and the Initialization Vector IV!
    
   [..] If the key is defined as a 128-bit long array key[127..0] = {b127 ... b0} where 
        b127 is the MSB and b0 the LSB, the key must be stored in MCU memory 
        (+) as a sequence of words where the MSB word comes first (occupies the
          lowest memory address) 
        (+) where each word is byte-swapped:
         (++)   address n+0 : 0b b103 .. b96 b111 .. b104 b119 .. b112 b127 .. b120
         (++)   address n+4 : 0b b71 .. b64 b79 .. b72 b87 .. b80 b95 .. b88
         (++)   address n+8 : 0b b39 .. b32 b47 .. b40 b55 .. b48 b63 .. b56
         (++)   address n+C : 0b b7 .. b0 b15 .. b8 b23 .. b16 b31 .. b24                 
    [..] Hereafter, another illustration when considering a 128-bit long key made of 16 bytes {B15..B0}.
        The 4 32-bit words that make the key must be stored as follows in MCU memory:  
         (+)    address n+0 : 0x B12 B13 B14 B15
         (+)    address n+4 : 0x B8 B9 B10 B11
         (+)    address n+8 : 0x B4 B5 B6 B7
         (+)    address n+C : 0x B0 B1 B2 B3  
    [..]  which leads to the expected setting  
      (+)       AES_KEYR3 = 0x B15 B14 B13 B12   
      (+)       AES_KEYR2 = 0x B11 B10 B9 B8      
      (+)       AES_KEYR1 = 0x B7 B6 B5 B4        
      (+)       AES_KEYR0 = 0x B3 B2 B1 B0      
   
   [..]  Same format must be applied for a 256-bit long key made of 32 bytes {B31..B0}. 
         The 8 32-bit words that make the key must be stored as follows in MCU memory:
         (+)    address n+00 : 0x B28 B29 B30 B31
         (+)    address n+04 : 0x B24 B25 B26 B27
         (+)    address n+08 : 0x B20 B21 B22 B23
         (+)    address n+0C : 0x B16 B17 B18 B19            
         (+)    address n+10 : 0x B12 B13 B14 B15
         (+)    address n+14 : 0x B8 B9 B10 B11
         (+)    address n+18 : 0x B4 B5 B6 B7
         (+)    address n+1C : 0x B0 B1 B2 B3 
    [..]  which leads to the expected setting 
      (+)       AES_KEYR7 = 0x B31 B30 B29 B28   
      (+)       AES_KEYR6 = 0x B27 B26 B25 B24      
      (+)       AES_KEYR5 = 0x B23 B22 B21 B20        
      (+)       AES_KEYR4 = 0x B19 B18 B17 B16       
      (+)       AES_KEYR3 = 0x B15 B14 B13 B12   
      (+)       AES_KEYR2 = 0x B11 B10 B9 B8      
      (+)       AES_KEYR1 = 0x B7 B6 B5 B4        
      (+)       AES_KEYR0 = 0x B3 B2 B1 B0           
   
   [..] Initialization Vector IV (4 32-bit words) format must follow the same as 
        that of a 128-bit long key.
