STM32 MCUs Security

STM32F439ZI, the HASH_Start_DMA() function works as expected if the size parameter is 16, elsewhere it doesn't calculate anything

I'm trying to use the STM32F439ZI HASH accelerator with the following code:#define INPUT_SIZE 16 static uint8_t hash_test_buffer[224] = {0};   static uint8_t hash_test_output[224];   HASH_Start_DMA(&hhash, hash_test_buffer, INPUT_SIZE, HASH_ALGOSEL...

Is it possible to read STM32L0 with RDP L1 using another STM32L4 without RDP?

I have one STM32L4 that act as master MCU.This master MCU is set with RDP L0. I have another slave STM32L0 with RDP L1. I tried to read this STM32L0 using this master MCU but did not get any result. It seems like this slave MCU did not run the code c...

Hi, I want to ask if it is possible for me to implement FTPS and HTTPS using STM32F303RC and W5500, all datasheets I see exclude the F3 family, is it possible? Thanks for reading this, and sorry for wasting your time.

Determine the padding to save the firmware SHA256 using STM32F746GDISCOVERY to verify integrity

I am trying to implement a firmware integrity check using the Cryptographic Library (X-CUBE-CRYPTOLIB) for this I have to calculate the SHA256 checksum and then determine the padding and include it in the binary that I will upload to the board.I've b...

STM32 has the capability to perform checksum self checking.If no, there is some way to verify that the program have been loaded properly.

Help in SBSFU memory

Hi all,I generated the SBSFU file. now i am getting another issue, I was thinking to program the .bin file using CubePrg (DFU method)so I loaded the .bin file which created using sbsfu, then I set the start address as 0x080000000 or 0x0 and trying to...
