bogdanm 0:9b334a45a8ff 18 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 19 ==============================================================================
bogdanm 0:9b334a45a8ff 20 [..]
bogdanm 0:9b334a45a8ff 21 The CRYP HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 22
bogdanm 0:9b334a45a8ff 23 (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
bogdanm 0:9b334a45a8ff 24 (++) Enable the CRYP interface clock using __HAL_RCC_AES_CLK_ENABLE()
bogdanm 0:9b334a45a8ff 25 (++) In case of using interrupts (e.g. HAL_CRYP_AES_IT())
bogdanm 0:9b334a45a8ff 26 (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
bogdanm 0:9b334a45a8ff 27 (+++) Enable the AES IRQ handler using HAL_NVIC_EnableIRQ()
bogdanm 0:9b334a45a8ff 28 (+++) In AES IRQ handler, call HAL_CRYP_IRQHandler()
bogdanm 0:9b334a45a8ff 29 (++) In case of using DMA to control data transfer (e.g. HAL_CRYPEx_AES_DMA())
bogdanm 0:9b334a45a8ff 30 (+++) Enable the DMA2 interface clock using
bogdanm 0:9b334a45a8ff 31 __HAL_RCC_DMA2_CLK_ENABLE()
bogdanm 0:9b334a45a8ff 32 (+++) Configure and enable two DMA channels one for managing data transfer from
bogdanm 0:9b334a45a8ff 33 memory to peripheral (input channel) and another channel for managing data
bogdanm 0:9b334a45a8ff 34 transfer from peripheral to memory (output channel)
bogdanm 0:9b334a45a8ff 35 (+++) Associate the initialized DMA handle to the CRYP DMA handle
bogdanm 0:9b334a45a8ff 36 using __HAL_LINKDMA()
bogdanm 0:9b334a45a8ff 37 (+++) Configure the priority and enable the NVIC for the transfer complete
bogdanm 0:9b334a45a8ff 38 interrupt on the two DMA channels. The output channel should have higher
bogdanm 0:9b334a45a8ff 39 priority than the input channel.
bogdanm 0:9b334a45a8ff 40 Resort to HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
bogdanm 0:9b334a45a8ff 41
bogdanm 0:9b334a45a8ff 42 (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures:
bogdanm 0:9b334a45a8ff 43 (++) The data type: 1-bit, 8-bit, 16-bit and 32-bit
bogdanm 0:9b334a45a8ff 44 (++) The AES operating mode (encryption, key derivation and/or decryption)
bogdanm 0:9b334a45a8ff 45 (++) The AES chaining mode (ECB, CBC, CTR, GCM, GMAC, CMAC)
bogdanm 0:9b334a45a8ff 46 (++) The encryption/decryption key if so required
bogdanm 0:9b334a45a8ff 47 (++) The initialization vector or nonce if applicable (not used in ECB mode).
bogdanm 0:9b334a45a8ff 48
bogdanm 0:9b334a45a8ff 49 (#)Three processing (encryption/decryption) functions are available:
bogdanm 0:9b334a45a8ff 50 (++) Polling mode: encryption and decryption APIs are blocking functions
bogdanm 0:9b334a45a8ff 51 i.e. they process the data and wait till the processing is finished
bogdanm 0:9b334a45a8ff 52 (++) Interrupt mode: encryption and decryption APIs are not blocking functions
bogdanm 0:9b334a45a8ff 53 i.e. they process the data under interrupt
bogdanm 0:9b334a45a8ff 54 (++) DMA mode: encryption and decryption APIs are not blocking functions
bogdanm 0:9b334a45a8ff 55 i.e. the data transfer is ensured by DMA
bogdanm 0:9b334a45a8ff 56
bogdanm 0:9b334a45a8ff 57 (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
