- * This file provides firmware functions to manage the following
- * functionalities of the Cryptography (CRYP) peripheral:
- * + Initialization and de-initialization functions
- * + Processing functions by algorithm using polling mode
- * + Processing functions by algorithm using interrupt mode
- * + Processing functions by algorithm using DMA mode
- * + Peripheral State functions

- ==============================================================================
- ##### 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 __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 DMA2 interface clock using
- (++) __DMA2_CLK_ENABLE()
- (+) Configure and enable two DMA Channels one for managing data transfer from
- memory to peripheral (input channel) and another channel for managing data
- transfer from peripheral to memory (output channel)
- (+) 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()
- (++) 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 encryption/decryption key.
- (##) 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 for the 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.
