Hello everyone,I was wondering the proper way to use the STM32_CHACHA_20_Encrypt() and STM32_CHACHA_20_Decrypt() functions available on the ST CryptoLib. I run the standard demo code on a STM32F072C8 MCU and it apparently run correctly, returning PAS...
The code from the 1.16 example builds fine in the EWARM. It writes the source blocks to the terminal, but as I see in the debugger, it fails to encrypt the input block. That times out as it fails to return a HAL_OK status. /* Start decrypting aCypher...
I have the nucleo l152RE board and am trying to use this for following the mooc on sbsfu. It is possible for me to build (in cube IDE) both SECoreBin and SBSFU images. however, when building the UserApp it fails on the postbuild script. During build,...
I am using x-cube-sbsfu version 2.4.0 on a custom designed board using the STM32F722. I have ported the single slot code (1_Image) for the STM32F769I-Discovery board to the custom board. I have come across what looks like an error in the sfu_low_leve...
I know this was cracked before, but required high skills and expensive equipment, but nowthis method makes it really easy, basically anyone can do it.Any official statement concerning this from ST?Like the list of devices which are affected, possible...
The ECDSA implementation in cryptolib does not provide means of implementing ECDSA without a random number. RFC6979 is a secure way of doing ECDSA without a random number, it is used in the blockchain implementations (bitcoin, ethereum)
Hello community,I have a few of questions regarding SFI:1) Does STM32H753AI support SFI (Secure Firmware Install)?2) Can I use SWD for the SFI?3) Is there any recommended HSM smart card reader for the SFI?Thank you :)
Hi all,I have two different batches of Revision V STM32H750VBT6. All units in one of the batches (Date Code 045) has issue with the hash peripheral while the one (Date Code 928) is working completely fine.I created a new basic project for testing thi...
I am using STM32L4A6VG with 1 MB flash and my application is about 600+KB. I want to update the user app from an external flash and need some guide to modify SBSFU.After reading these 2 examples (STM32CubeExpansion_SBSFU_V2.4.0\Projects\B-L475E-IOT0...
