| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| The CRYP HAL driver can be used in CRYP IP 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_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_Encrypt_DMA()) |
| (+++) Enable the DMAx interface clock using __RCC_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 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() and HAL_NVIC_EnableIRQ() |
| |
| (#)Initialize the CRYP according to the specified parameters : |
| (##) The data type: 1-bit, 8-bit, 16-bit or 32-bit. |
| (##) The key size: 128, 192 or 256. |
| (##) The AlgoMode DES/ TDES Algorithm ECB/CBC or AES Algorithm ECB/CBC/CTR. |
| (##) The initialization vector (counter). It is not used in ECB mode. |
| (##) The key buffer used for encryption/decryption. |
| |
| (#)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_Encrypt & HAL_CRYP_Decrypt |
| (##) Interrupt mode: encryption and decryption APIs are not blocking functions |
| i.e. they process the data under interrupt, |
| e.g. HAL_CRYP_Encrypt_IT & HAL_CRYP_Decrypt_IT |
| (##) DMA mode: encryption and decryption APIs are not blocking functions |
| i.e. the data transfer is ensured by DMA, |
| e.g. HAL_CRYP_Encrypt_DMA & HAL_CRYP_Decrypt_DMA |
| |
| (#)When the processing function is called at first time after HAL_CRYP_Init() |
| the CRYP peripheral is configured and processes the buffer in input. |
| At second call, no need to Initialize the CRYP, user have to get current configuration via |
| HAL_CRYP_GetConfig() API, then only HAL_CRYP_SetConfig() is requested to set |
| new parametres, finally user can start encryption/decryption. |
| |
| (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral. |
| |
| [..] |
| The cryptographic processor supports following standards: |
| (#) The data encryption standard (DES) and Triple-DES (TDES) supported only by CRYP1 IP: |
| (##)64-bit data block processing |
| (##) chaining modes supported : |
| (+++) Electronic Code Book(ECB) |
| (+++) Cipher Block Chaining (CBC) |
| (##) keys length supported :64-bit, 128-bit and 192-bit. |
| (#) The advanced encryption standard (AES) supported by CRYP1: |
| (##)128-bit data block processing |
| (##) chaining modes supported : |
| (+++) Electronic Code Book(ECB) |
| (+++) Cipher Block Chaining (CBC) |
| (+++) Counter mode (CTR) |
| (##) keys length Supported : |
| (+++) for CRYP1 IP: 128-bit, 192-bit and 256-bit. |
| |
| *** Callback registration *** |
| ============================================= |
| [..] |
| The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| Use Functions @ref HAL_CRYP_RegisterCallback() or HAL_CRYP_RegisterXXXCallback() |
| to register an interrupt callback. |
| [..] |
| Function @ref HAL_CRYP_RegisterCallback() allows to register following callbacks: |
| (+) InCpltCallback : Input FIFO transfer completed callback. |
| (+) OutCpltCallback : Output FIFO transfer completed callback. |
| (+) ErrorCallback : callback for error detection. |
| (+) MspInitCallback : CRYP MspInit. |
| (+) MspDeInitCallback : CRYP MspDeInit. |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| [..] |
| Use function @ref HAL_CRYP_UnRegisterCallback() to reset a callback to the default |
| weak function. |
| @ref HAL_CRYP_UnRegisterCallback() takes as parameters the HAL peripheral handle, |
| and the Callback ID. |
| This function allows to reset following callbacks: |
| (+) InCpltCallback : Input FIFO transfer completed callback. |
| (+) OutCpltCallback : Output FIFO transfer completed callback. |
| (+) ErrorCallback : callback for error detection. |
| (+) MspInitCallback : CRYP MspInit. |
| (+) MspDeInitCallback : CRYP MspDeInit. |
| [..] |
| By default, after the @ref HAL_CRYP_Init() and when the state is HAL_CRYP_STATE_RESET |
| all callbacks are set to the corresponding weak functions : |
| examples @ref HAL_CRYP_InCpltCallback() , @ref HAL_CRYP_OutCpltCallback(). |
| Exception done for MspInit and MspDeInit functions that are |
| reset to the legacy weak function in the @ref HAL_CRYP_Init()/ @ref HAL_CRYP_DeInit() only when |
| these callbacks are null (not registered beforehand). |
| if not, MspInit or MspDeInit are not null, the @ref HAL_CRYP_Init() / @ref HAL_CRYP_DeInit() |
| keep and use the user MspInit/MspDeInit functions (registered beforehand) |
| |
| Callbacks can be registered/unregistered in HAL_CRYP_STATE_READY state only. |
| Exception done MspInit/MspDeInit callbacks that can be registered/unregistered |
| in HAL_CRYP_STATE_READY or HAL_CRYP_STATE_RESET state, |
| thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using @ref HAL_CRYP_RegisterCallback() before calling @ref HAL_CRYP_DeInit() |
| or @ref HAL_CRYP_Init() function. |
| [..] |
| When The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registration feature is not available and all callbacks |
| are set to the corresponding weak functions. |
