  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
    [..]
      The CRYP HAL driver can be used in CRYP or TinyAES IP 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()or __HAL_RCC_AES_CLK_ENABLE for TinyAES IP
         (##) In case of using interrupts (e.g. HAL_CRYP_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_Encrypt_DMA())
             (+++) Enable the DMAx interface clock using __RCC_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 according to the specified parameters :
         (##) The data type: 1-bit, 8-bit, 16-bit or 32-bit.
         (##) The key size: 128, 192 or 256.
         (##) The AlgoMode DES/ TDES Algorithm ECB/CBC or AES Algorithm ECB/CBC/CTR/GCM or CCM.
         (##) The initialization vector (counter). It is not used in ECB mode.
         (##) The key buffer used for encryption/decryption.
         (##) The Header used only in AES GCM and CCM Algorithm for authentication.
         (##) The HeaderSize The size of header buffer in word.
         (##) The B0 block is the first authentication block used only  in AES CCM 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_Encrypt & HAL_CRYP_Decrypt
         (##) Interrupt mode: encryption and decryption APIs are not blocking functions
              i.e. they process the data under interrupt,
              e.g. HAL_CRYP_Encrypt_IT & HAL_CRYP_Decrypt_IT
         (##) DMA mode: encryption and decryption APIs are not blocking functions
              i.e. the data transfer is ensured by DMA,
              e.g. HAL_CRYP_Encrypt_DMA & HAL_CRYP_Decrypt_DMA

      (#)When the processing function is called at first time after HAL_CRYP_Init()
         the CRYP peripheral is configured and processes the buffer in input.
         At second call, no need to Initialize the CRYP, user have to get current configuration via
         HAL_CRYP_GetConfig() API, then only  HAL_CRYP_SetConfig() is requested to set
         new parametres, finally user can  start encryption/decryption.

       (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.

       (#)To process a single message with consecutive calls to HAL_CRYP_Encrypt() or HAL_CRYP_Decrypt()
          without having to configure again the Key or the Initialization Vector between each API call,
          the field KeyIVConfigSkip of the initialization structure must be set to CRYP_KEYIVCONFIG_ONCE.
          Same is true for consecutive calls of HAL_CRYP_Encrypt_IT(), HAL_CRYP_Decrypt_IT(), HAL_CRYP_Encrypt_DMA()
          or HAL_CRYP_Decrypt_DMA().

    [..]
      The cryptographic processor supports following standards:
      (#) The data encryption standard (DES) and Triple-DES (TDES) supported only by CRYP1 IP:
         (##)64-bit data block processing
         (##) chaining modes supported :
             (+++)  Electronic Code Book(ECB)
             (+++)  Cipher Block Chaining (CBC)
         (##) keys length supported :64-bit, 128-bit and 192-bit.
      (#) The advanced encryption standard (AES) supported  by CRYP1 & TinyAES IP:
         (##)128-bit data block processing
         (##) chaining modes supported :
             (+++)  Electronic Code Book(ECB)
             (+++)  Cipher Block Chaining (CBC)
             (+++)  Counter mode (CTR)
             (+++)  Galois/counter mode (GCM/GMAC)
             (+++)  Counter with Cipher Block Chaining-Message(CCM)
         (##) keys length Supported :
             (+++) for CRYP1 IP: 128-bit, 192-bit and 256-bit.
             (+++) for TinyAES IP:  128-bit and 256-bit

    [..]  This section describes the AES Galois/counter mode (GCM) supported by both CRYP1 IP:
      (#)  Algorithm supported :
         (##) Galois/counter mode (GCM)
         (##) Galois message authentication code (GMAC) :is exactly the same as
              GCM algorithm composed only by an header.
      (#)  Four phases are performed in GCM :
         (##) Init phase: IP prepares the GCM hash subkey (H) and do the IV processing
         (##) Header phase: IP processes the Additional Authenticated Data (AAD), with hash
          computation only.
         (##) Payload phase: IP processes the plaintext (P) with hash computation + keystream
          encryption + data XORing. It works in a similar way for ciphertext (C).
         (##) Final phase: IP generates the authenticated tag (T) using the last block of data.
      (#)  structure of message construction in GCM is defined as below  :
         (##) 16 bytes Initial Counter Block (ICB)composed of IV and counter
         (##) The authenticated header A (also knows as Additional Authentication Data AAD)
          this part of the message is only authenticated, not encrypted.
         (##) The plaintext message P is both authenticated and encrypted as ciphertext.
          GCM standard specifies that ciphertext has same bit length as the plaintext.
         (##) The last block is composed of the length of A (on 64 bits) and the length of ciphertext
          (on 64 bits)

    [..]  This section describe The AES Counter with Cipher Block Chaining-Message
          Authentication Code (CCM) supported by both CRYP1 IP:
      (#)  Specific parameters for CCM  :

         (##) B0 block  : According to NIST Special Publication 800-38C,
            The first block B0 is formatted as follows, where l(m) is encoded in
            most-significant-byte first order(see below table 3)

              (+++)  Q: a bit string representation of the octet length of P (plaintext)
              (+++)  q The octet length of the binary representation of the octet length of the payload
              (+++)  A nonce (N), n The octet length of the where n+q=15.
              (+++)  Flags: most significant octet containing four flags for control information,
              (+++)  t The octet length of the MAC.
         (##) B1 block (header) : associated data length(a) concatenated with Associated Data (A)
              the associated data length expressed in bytes (a) defined as below:
            (+++)  If 0 < a < 216-28, then it is encoded as [a]16, i.e. two octets
            (+++)  If 216-28 < a < 232, then it is encoded as 0xff || 0xfe || [a]32, i.e. six octets
            (+++)  If 232 < a < 264, then it is encoded as 0xff || 0xff || [a]64, i.e. ten octets
         (##) CTRx block  : control blocks
            (+++) Generation of CTR1 from first block B0 information :
              equal to B0 with first 5 bits zeroed and most significant bits storing octet
              length of P also zeroed, then incremented by one ( see below Table 4)
            (+++) Generation of CTR0: same as CTR1 with bit[0] set to zero.

      (#)  Four phases are performed in CCM for CRYP1 IP:
         (##) Init phase: IP prepares the GCM hash subkey (H) and do the IV processing
         (##) Header phase: IP processes the Additional Authenticated Data (AAD), with hash
          computation only.
         (##) Payload phase: IP processes the plaintext (P) with hash computation + keystream
          encryption + data XORing. It works in a similar way for ciphertext (C).
         (##) Final phase: IP generates the authenticated tag (T) using the last block of data.

  *** Callback registration ***
  =============================================

  The compilation define  USE_HAL_CRYP_REGISTER_CALLBACKS when set to 1
  allows the user to configure dynamically the driver callbacks.
  Use Functions @ref HAL_CRYP_RegisterCallback() or HAL_CRYP_RegisterXXXCallback()
  to register an interrupt callback.

  Function @ref HAL_CRYP_RegisterCallback() allows to register following callbacks:
    (+) InCpltCallback     :  Input FIFO transfer completed callback.
    (+) OutCpltCallback    : Output FIFO transfer completed callback.
    (+) ErrorCallback      : callback for error detection.
    (+) MspInitCallback    : CRYP MspInit.
    (+) MspDeInitCallback  : CRYP MspDeInit.
  This function takes as parameters the HAL peripheral handle, the Callback ID
  and a pointer to the user callback function.

  Use function @ref HAL_CRYP_UnRegisterCallback() to reset a callback to the default
  weak function.
  @ref HAL_CRYP_UnRegisterCallback() takes as parameters the HAL peripheral handle,
  and the Callback ID.
  This function allows to reset following callbacks:
    (+) InCpltCallback     :  Input FIFO transfer completed callback.
    (+) OutCpltCallback    : Output FIFO transfer completed callback.
    (+) ErrorCallback      : callback for error detection.
    (+) MspInitCallback    : CRYP MspInit.
    (+) MspDeInitCallback  : CRYP MspDeInit.

  By default, after the @ref HAL_CRYP_Init() and when the state is HAL_CRYP_STATE_RESET
  all callbacks are set to the corresponding weak functions :
  examples @ref HAL_CRYP_InCpltCallback() , @ref HAL_CRYP_OutCpltCallback().
  Exception done for MspInit and MspDeInit functions that are
  reset to the legacy weak function in the @ref HAL_CRYP_Init()/ @ref HAL_CRYP_DeInit() only when
  these callbacks are null (not registered beforehand).
  if not, MspInit or MspDeInit are not null, the @ref HAL_CRYP_Init() / @ref HAL_CRYP_DeInit()
  keep and use the user MspInit/MspDeInit functions (registered beforehand)

  Callbacks can be registered/unregistered in HAL_CRYP_STATE_READY state only.
  Exception done MspInit/MspDeInit callbacks that can be registered/unregistered
  in HAL_CRYP_STATE_READY or HAL_CRYP_STATE_RESET state,
  thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
  In that case first register the MspInit/MspDeInit user callbacks
  using @ref HAL_CRYP_RegisterCallback() before calling @ref HAL_CRYP_DeInit()
  or @ref HAL_CRYP_Init() function.

  When The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS is set to 0 or
  not defined, the callback registration feature is not available and all callbacks
  are set to the corresponding weak functions.
