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 - * - * <h2><center>© COPYRIGHT(c) 2015 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.
