/** ****************************************************************************** * @file stm32f4xx_hal_cryp_ex.c * @author MCD Application Team * @brief Extended CRYP HAL module driver * This file provides firmware functions to manage the following * functionalities of CRYP extension peripheral: * + Extended AES processing functions * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] The CRYP Extension 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_CRYPEx_AESGCM_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_AES_ECB_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. Its 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_CRYPEx_AESGCM_Encrypt() (##) Interrupt mode: encryption and decryption APIs are not blocking functions i.e. they process the data under interrupt e.g. HAL_CRYPEx_AESGCM_Encrypt_IT() (##) DMA mode: encryption and decryption APIs are not blocking functions i.e. the data transfer is ensured by DMA e.g. HAL_CRYPEx_AESGCM_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. (#)In AES-GCM and AES-CCM modes are an authenticated encryption algorithms which provide authentication messages. HAL_AES_GCM_Finish() and HAL_AES_CCM_Finish() are used to provide those authentication messages. Call those functions after the processing ones (polling, interrupt or DMA). e.g. in AES-CCM mode call HAL_CRYPEx_AESCCM_Encrypt() to encrypt the plain data then call HAL_CRYPEx_AESCCM_Finish() to get the authentication message -@- For CCM Encrypt/Decrypt API's, only DataType = 8-bit is supported by this version. -@- The HAL_CRYPEx_AESGCM_xxxx() implementation is limited to 32bits inputs data length (Plain/Cyphertext, Header) compared with GCM standards specifications (800-38D). (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral. @endverbatim ****************************************************************************** * @attention * * <h2><center>&copy; COPYRIGHT(c) 2017 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
