/** ****************************************************************************** * @file stm32f4xx_hal_cryp.c * @author MCD Application Team * @version V1.6.0 * @date 04-November-2016 * @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. @endverbatim ****************************************************************************** * @attention * *
