c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	11 ==============================================================================
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	12 ##### How to use this driver #####
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	13 ==============================================================================
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	14 [..]
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	15 The CRYP Extension HAL driver can be used as follows:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	16 (#)Initialize the CRYP low level resources by implementing the HAL_CRYP_MspInit():
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	17 (##) Enable the CRYP interface clock using __HAL_RCC_CRYP_CLK_ENABLE()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	18 (##) In case of using interrupts (e.g. HAL_CRYPEx_AESGCM_Encrypt_IT())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	19 (+++) Configure the CRYP interrupt priority using HAL_NVIC_SetPriority()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	20 (+++) Enable the CRYP IRQ handler using HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	21 (+++) In CRYP IRQ handler, call HAL_CRYP_IRQHandler()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	22 (##) In case of using DMA to control data transfer (e.g. HAL_AES_ECB_Encrypt_DMA())
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	23 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	24 (+++) Configure and enable two DMA streams one for managing data transfer from
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	25 memory to peripheral (input stream) and another stream for managing data
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	26 transfer from peripheral to memory (output stream)
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	27 (+++) Associate the initialized DMA handle to the CRYP DMA handle
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	28 using __HAL_LINKDMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	29 (+++) Configure the priority and enable the NVIC for the transfer complete
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	30 interrupt on the two DMA Streams. The output stream should have higher
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	31 priority than the input stream HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	32 (#)Initialize the CRYP HAL using HAL_CRYP_Init(). This function configures mainly:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	33 (##) The data type: 1-bit, 8-bit, 16-bit and 32-bit
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	34 (##) The key size: 128, 192 and 256. This parameter is relevant only for AES
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	35 (##) The encryption/decryption key. Its size depends on the algorithm
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	36 used for encryption/decryption
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	37 (##) The initialization vector (counter). It is not used ECB mode.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	38 (#)Three processing (encryption/decryption) functions are available:
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	39 (##) Polling mode: encryption and decryption APIs are blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	40 i.e. they process the data and wait till the processing is finished
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	41 e.g. HAL_CRYPEx_AESGCM_Encrypt()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	42 (##) Interrupt mode: encryption and decryption APIs are not blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	43 i.e. they process the data under interrupt
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	44 e.g. HAL_CRYPEx_AESGCM_Encrypt_IT()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	45 (##) DMA mode: encryption and decryption APIs are not blocking functions
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	46 i.e. the data transfer is ensured by DMA
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	47 e.g. HAL_CRYPEx_AESGCM_Encrypt_DMA()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	48 (#)When the processing function is called at first time after HAL_CRYP_Init()
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	49 the CRYP peripheral is initialized and processes the buffer in input.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	50 At second call, the processing function performs an append of the already
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	51 processed buffer.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	52 When a new data block is to be processed, call HAL_CRYP_Init() then the
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	53 processing function.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	54 (#)In AES-GCM and AES-CCM modes are an authenticated encryption algorithms
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	55 which provide authentication messages.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	56 HAL_AES_GCM_Finish() and HAL_AES_CCM_Finish() are used to provide those
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	57 authentication messages.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	58 Call those functions after the processing ones (polling, interrupt or DMA).
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	59 e.g. in AES-CCM mode call HAL_CRYPEx_AESCCM_Encrypt() to encrypt the plain data
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	60 then call HAL_CRYPEx_AESCCM_Finish() to get the authentication message
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	61 -@- For CCM Encrypt/Decrypt API's, only DataType = 8-bit is supported by this version.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	62 -@- The HAL_CRYPEx_AESGCM_xxxx() implementation is limited to 32bits inputs data length
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	63 (Plain/Cyphertext, Header) compared with GCM standards specifications (800-38D).
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	64 (#)Call HAL_CRYP_DeInit() to deinitialize the CRYP peripheral.
