- ==============================================================================
- ##### 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 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 initilalized 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.
