I am trying to create a mechanism of verification where I sign a file on the PC save it to a disk on a key device and then verify it by the MCU after saving it to internal flash.The PC is doing the signing process and the MCU should only do the verif...
I'm trying to port the SBSFU to STM32H735. I started from the project for the NUCLEO-H753ZI.I get errors in sfu_fwimg_core.c on FW_INFO_TOT_LEN but where is this defined?A simple grep -r turns up nothing.Thanks!
We are evaluating if we can use the STM32WLE5, to interface to existing devices .A critical factor is the expected endianness of the data. I have seen no reference in the docs if this can be set, so I have provided an example message and would like t...
Hello,one question (or feature request):I try to use the STM32 crypto library (v1.3.1 software implementation) on STM32WB. I activated the RNG and CRC but the calculated results (encryption/decryption, cmac) are not ok. Are there other things to do?I...
Hello,I want to calculate the CRC (32 bit) of image at post build and insert it in a known location in the image.In order to do it I should perform the following steps:a) Definition of placeholder in linker script fileb) Post build steps: b.1) Ca...
HiI want to use the Cryptographic peripheral on the above nucleo board, in the following way.Serial message from embedded board-->H745 crypto engine-->wireless transmission-->Decrypt packet on remote x86 laptopAnd the reverse direction tooSo clearly ...
Hi!I'm triying to set the CRC-16-IBM: X16+X15+X2+1, but CUBEMx does not allow it. In fact, I cannot introduce any polynomial.Is it a CUBE issue? How can I introduce the CRC-16 IBM polynomial ?Thank you
HelloIn STM32 Crypto Library, there are function "AES_CMAC_Encrypt_Init", "AES_CMAC_Encrypt_Append" and "AES_CMAC_Encrypt_Finish" to calculate the authentication code of a plain text.How can this be done on STM32WB using the CRYP peripheral (HAL driv...
