##### 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.
