  ==============================================================================
                      ##### Encrypt Decrypt  functions #####
  ==============================================================================
    [..]  This section provides API allowing to Encrypt/Decrypt Data following
          Standard DES/TDES or AES, and Algorithm configured by the user:
      (+) Standard DES/TDES only supported by CRYP1 IP, below list of Algorithm supported :
           - Electronic Code Book(ECB)
           - Cipher Block Chaining (CBC)
      (+) Standard AES  supported by CRYP1 IP & TinyAES, list of Algorithm supported:
           - Electronic Code Book(ECB)
           - Cipher Block Chaining (CBC)
           - Counter mode (CTR)
           - Cipher Block Chaining (CBC)
           - Counter mode (CTR)
           - Galois/counter mode (GCM)
           - Counter with Cipher Block Chaining-Message(CCM)
    [..]  Three processing functions are available:
      (+) Polling mode : HAL_CRYP_Encrypt & HAL_CRYP_Decrypt
      (+) Interrupt mode : HAL_CRYP_Encrypt_IT & HAL_CRYP_Decrypt_IT
      (+) DMA mode : HAL_CRYP_Encrypt_DMA & HAL_CRYP_Decrypt_DMA
