* @brief CRYP HAL module driver. | |
* | |
* 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 __HAL_RCC_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 | |
(++) __HAL_RCC_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. | |
