Hi,I am new the the development and I have been testing the hardware aes module.I have tested against a known vector and the results differ from what is expected, I have checked the test vectors using AES provider in .NET and I get the results I expe...
I have a module that uses the STM32F091RC MCU and trying to connect it with software using C# language.At the first the connection has worked properly, then I've used the CRC32 to verify the sent data but it didn't work.Ive read the "Application note...
Hi,I have (for example) a byte array with the size of 6. Now I want to calculate its crc32 value. The first 4 bytes are no problem - I put them in as word, but what about the last 2 bytes?Thanks for the Help in advance.BRNico
Hello,I now understand that I should have asked the question differently.Let's say we have 2 applications: secured and non-secured application.The secured is placed in inetrnal flash, just as done in the demo of SBSFU,But the non secured should be pl...
I have a file from ST, not sure where it comes from but the header has:sha1_alt.c for SHA1 HASHCopyright (c) 2017, STMicroelectronicsI am getting issues with the function that call HAL_HASH_SHA1_Accumulate function.They are no checking for size/len i...
Hi,According to application note for STM32F4xx protection features ,the reverse from RDP L2 to RDP L1 is not possible due to a JTAG fuse, does this mean also that the MCU can check the fuses before checking the RDP? Is it possible to change the Level...
I'm using the hardware hash processor of an STM32F756 to calculate the MD5 of string "user:realm:password", but the result is wrong. I'm using the HAL library, this is my code.static void AuthRespCalc(char * username, char *realm, char * password) { ...
Dear experts,I'd like to try the Secure Access mode of H753, but overwhelmed by the SBSFU and SFI documentation.I'm thinking about a minimal test for the "secure user memory" - without SFI, Secure Package Creator etc., or as little as possible:Burn a...
Hi all,I am writing an application on STMCubeIDE and i need to append the its CRC at the end of the generated hex/bin file. Is there any shortcut or functionality in order to do that on STMCubeIDE? And if not, how would you suggest me to do that? Tha...
