| * @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 using polling mode |
| * + Processing functions using interrupt mode |
| * + Processing functions using DMA mode |
| * + Peripheral State functions |
| * |
| @verbatim |
| ============================================================================== |
| ##### 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_AES_CLK_ENABLE() |
| (++) In case of using interrupts (e.g. HAL_CRYP_AES_IT()) |
| (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority() |
| (+++) Enable the AES IRQ handler using HAL_NVIC_EnableIRQ() |
| (+++) In AES IRQ handler, call HAL_CRYP_IRQHandler() |
| (++) In case of using DMA to control data transfer (e.g. HAL_CRYPEx_AES_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 channels. The output channel should have higher |
| priority than the input channel. |
| Resort to HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ() |
| |
| (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures: |
| (++) The data type: 1-bit, 8-bit, 16-bit and 32-bit |
| (++) The AES operating mode (encryption, key derivation and/or decryption) |
| (++) The AES chaining mode (ECB, CBC, CTR, GCM, GMAC, CMAC when applicable, CCM when applicable) |
| (++) The encryption/decryption key if so required |
| (++) The initialization vector or nonce if applicable (not used in 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 |
| (++) Interrupt mode: encryption and decryption APIs are not blocking functions |
| i.e. they process the data under interrupt |
| (++) DMA mode: encryption and decryption APIs are not blocking functions |
| i.e. the data transfer is ensured by DMA |
| |
| (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral. |
| |
| *** Callback registration *** |
| =================================== |
| [..] |
| (#) The compilation define USE_HAL_CRYP_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| Use function @ref HAL_CRYP_RegisterCallback() to register a user callback. |
| |
| (#) Function @ref HAL_CRYP_RegisterCallback() allows to register following callbacks: |
| (+) InCpltCallback : callback for input DMA transfer completion. |
| (+) OutCpltCallback : callback for output DMA transfer completion. |
| (+) CompCpltCallback : callback for computation completion. |
| (+) ErrorCallback : callback for error. |
| (+) 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 (surcharged) function. |
| @ref HAL_CRYP_UnRegisterCallback() takes as parameters the HAL peripheral handle, |
| and the Callback ID. |
| This function allows to reset following callbacks: |
| (+) InCpltCallback : callback for input DMA transfer completion. |
| (+) OutCpltCallback : callback for output DMA transfer completion. |
| (+) CompCpltCallback : callback for computation completion. |
| (+) ErrorCallback : callback for error. |
| (+) MspInitCallback : CRYP MspInit. |
| (+) MspDeInitCallback : CRYP MspDeInit. |
| |
| (#) By default, after the @ref HAL_CRYP_Init and if the state is HAL_CRYP_STATE_RESET |
| all callbacks are reset to the corresponding legacy weak (surcharged) functions: |
| examples @ref HAL_CRYP_InCpltCallback(), @ref HAL_CRYP_ErrorCallback() |
| Exception done for MspInit and MspDeInit callbacks that are respectively |
| reset to the legacy weak (surcharged) functions in the @ref HAL_CRYP_Init |
| and @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 and @ref HAL_CRYP_DeInit |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand). |
| |
| Callbacks can be registered/unregistered in READY state only. |
| Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered |
| in READY or 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 registering feature is not available |
| and weak (surcharged) callbacks are used. |

| ##### Initialization and deinitialization functions ##### |
| ============================================================================== |
| [..] This section provides functions allowing to: |
| (+) Initialize the CRYP according to the specified parameters |
| in the CRYP_InitTypeDef and creates the associated handle |
| (+) DeInitialize the CRYP peripheral |
| (+) Initialize the CRYP MSP (MCU Specific Package) |
| (+) De-Initialize the CRYP MSP |
| |
| [..] |
| (@) Specific care must be taken to format the key and the Initialization Vector IV! |
| |
| [..] If the key is defined as a 128-bit long array key[127..0] = {b127 ... b0} where |
| b127 is the MSB and b0 the LSB, the key must be stored in MCU memory |
| (+) as a sequence of words where the MSB word comes first (occupies the |
| lowest memory address) |
| (+) where each word is byte-swapped: |
| (++) address n+0 : 0b b103 .. b96 b111 .. b104 b119 .. b112 b127 .. b120 |
| (++) address n+4 : 0b b71 .. b64 b79 .. b72 b87 .. b80 b95 .. b88 |
| (++) address n+8 : 0b b39 .. b32 b47 .. b40 b55 .. b48 b63 .. b56 |
| (++) address n+C : 0b b7 .. b0 b15 .. b8 b23 .. b16 b31 .. b24 |
| [..] Hereafter, another illustration when considering a 128-bit long key made of 16 bytes {B15..B0}. |
| The 4 32-bit words that make the key must be stored as follows in MCU memory: |
| (+) address n+0 : 0x B12 B13 B14 B15 |
| (+) address n+4 : 0x B8 B9 B10 B11 |
| (+) address n+8 : 0x B4 B5 B6 B7 |
| (+) address n+C : 0x B0 B1 B2 B3 |
| [..] which leads to the expected setting |
| (+) AES_KEYR3 = 0x B15 B14 B13 B12 |
| (+) AES_KEYR2 = 0x B11 B10 B9 B8 |
| (+) AES_KEYR1 = 0x B7 B6 B5 B4 |
| (+) AES_KEYR0 = 0x B3 B2 B1 B0 |
| |
| [..] Same format must be applied for a 256-bit long key made of 32 bytes {B31..B0}. |
| The 8 32-bit words that make the key must be stored as follows in MCU memory: |
| (+) address n+00 : 0x B28 B29 B30 B31 |
| (+) address n+04 : 0x B24 B25 B26 B27 |
| (+) address n+08 : 0x B20 B21 B22 B23 |
| (+) address n+0C : 0x B16 B17 B18 B19 |
| (+) address n+10 : 0x B12 B13 B14 B15 |
| (+) address n+14 : 0x B8 B9 B10 B11 |
| (+) address n+18 : 0x B4 B5 B6 B7 |
| (+) address n+1C : 0x B0 B1 B2 B3 |
| [..] which leads to the expected setting |
| (+) AES_KEYR7 = 0x B31 B30 B29 B28 |
| (+) AES_KEYR6 = 0x B27 B26 B25 B24 |
| (+) AES_KEYR5 = 0x B23 B22 B21 B20 |
| (+) AES_KEYR4 = 0x B19 B18 B17 B16 |
| (+) AES_KEYR3 = 0x B15 B14 B13 B12 |
| (+) AES_KEYR2 = 0x B11 B10 B9 B8 |
| (+) AES_KEYR1 = 0x B7 B6 B5 B4 |
| (+) AES_KEYR0 = 0x B3 B2 B1 B0 |
| |
| [..] Initialization Vector IV (4 32-bit words) format must follow the same as |
| that of a 128-bit long key. |
