## Detailed Description

AES Encrypt/Decrypt functions.

     ===============================================================================
                          ##### IO operation functions #####
     ===============================================================================
        This subsection provides a set of functions allowing to manage the AES encrypt or decrypt.

        (#) There are two mode of transfer:
           (++) Blocking mode: The communication is performed in polling mode.
               The HAL status of all data processing are returned by the same function
               after finishing transfer.
           (++) Non-Blocking mode: The communication is performed using Interrupts
               or DMA. These API return the HAL status.
               The end of the data processing will be indicated through the
               dedicated AES IRQ when using Interrupt mode or the DMA IRQ when
               using DMA mode.
               The hal_aes_done_callback() user callbacks will be executed respectively
               at the end of the encrypt or decrypt process
               The hal_aes_error_callback() user callback will be executed when a error is detected

        (#) Blocking mode API's are :
            (++) hal_aes_ecb_encrypt()
            (++) hal_aes_ecb_decrypt()
            (++) hal_aes_cbc_encrypt()
            (++) hal_aes_cbc_decrypt()

        (#) Non-Blocking mode API's with Interrupt are :
            (++) hal_aes_ecb_encrypt_it()
            (++) hal_aes_ecb_decrypt_it()
            (++) hal_aes_cbc_encrypt_it()
            (++) hal_aes_cbc_decrypt_it()

        (#) Non-Blocking mode API's with DMA are :
            (++) hal_aes_ecb_encrypt_dma()
            (++) hal_aes_ecb_decrypt_dma()
            (++) hal_aes_cbc_encrypt_dma()
            (++) hal_aes_cbc_decrypt_dma()

        (#) A set of encrypt or decrypt Callbacks are provided in Non_Blocking mode:
            (++) hal_aes_done_callback()
            (++) hal_aes_error_callback()

        (#) Non-Blocking mode transfers could be aborted using Abort API's :
            (++) hal_aes_abort()
            (++) hal_aes_abort_it()

        (#) For Abort services based on interrupts (hal_aes_abort_xxx_it), Abort Complete Callback is provided:
            (++) hal_aes_abort_cplt_callback()
