| 20 | ##### How to use this driver #####
|
---|
| 21 | ==============================================================================
|
---|
| 22 | [..]
|
---|
| 23 | The CRYP HAL driver can be used as follows:
|
---|
| 24 |
|
---|
| 25 | (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
|
---|
| 26 | (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()
|
---|
| 27 | (##) In case of using interrupts (e.g. HAL_CRYP_AESECB_Encrypt_IT())
|
---|
| 28 | (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
|
---|
| 29 | (+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
|
---|
| 30 | (+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
|
---|
| 31 | (##) In case of using DMA to control data transfer (e.g. HAL_CRYP_AESECB_Encrypt_DMA())
|
---|
| 32 | (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
|
---|
| 33 | (+++) Configure and enable two DMA streams one for managing data transfer from
|
---|
| 34 | memory to peripheral (input stream) and another stream for managing data
|
---|
| 35 | transfer from peripheral to memory (output stream)
|
---|
| 36 | (+++) Associate the initialized DMA handle to the CRYP DMA handle
|
---|
| 37 | using __HAL_LINKDMA()
|
---|
| 38 | (+++) Configure the priority and enable the NVIC for the transfer complete
|
---|
| 39 | interrupt on the two DMA Streams. The output stream should have higher
|
---|
| 40 | priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
|
---|
| 41 |
|
---|
| 42 | (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
|
---|
| 43 | (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
|
---|
| 44 | (##) The key size: 128, 192 and 256. This parameter is relevant only for AES
|
---|
| 45 | (##) The encryption/decryption key. It's size depends on the algorithm
|
---|
| 46 | used for encryption/decryption
|
---|
| 47 | (##) The initialization vector (counter). It is not used ECB mode.
|
---|
| 48 |
|
---|
| 49 | (#)Three processing (encryption/decryption) functions are available:
|
---|
| 50 | (##) Polling mode: encryption and decryption APIs are blocking functions
|
---|
| 51 | i.e. they process the data and wait till the processing is finished,
|
---|
| 52 | e.g. HAL_CRYP_AESCBC_Encrypt()
|
---|
| 53 | (##) Interrupt mode: encryption and decryption APIs are not blocking functions
|
---|
| 54 | i.e. they process the data under interrupt,
|
---|
| 55 | e.g. HAL_CRYP_AESCBC_Encrypt_IT()
|
---|
| 56 | (##) DMA mode: encryption and decryption APIs are not blocking functions
|
---|
| 57 | i.e. the data transfer is ensured by DMA,
|
---|
| 58 | e.g. HAL_CRYP_AESCBC_Encrypt_DMA()
|
---|
| 59 |
|
---|
| 60 | (#)When the processing function is called at first time after HAL_CRYP_Init()
|
---|
| 61 | the CRYP peripheral is initialized and processes the buffer in input.
|
---|
| 62 | At second call, the processing function performs an append of the already
|
---|
| 63 | processed buffer.
|
---|
| 64 | When a new data block is to be processed, call HAL_CRYP_Init() then the
|
---|
| 65 | processing function.
|
---|
| 66 |
|
---|
| 67 | (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
