- * @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
- * + AES processing functions
- * + DES processing functions
- * + TDES processing functions
- * + DMA callback functions
- * + CRYP IRQ handler management
- * + 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 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 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 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.

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