+ * @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
+ *
+ @verbatim
+ ==============================================================================
+ ##### 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.
