I need to implement some BigNumber math on an STM32F4 (bn.h, conv.h, modular.h). I would like to use functions such as W8_to_Big(), StAllocBig(), and InitBig(). Unfortunately I cannot find any information on how to use these functions. Are there any ...
The user manual (UM1924) says in section 15 RSA Algorithm:There are two structures that pass keys to the functions:•RSAprivKey_stt for the private key•RSApubKey_stt for the public keyAll members of the above functions should be filled by the user bef...
Hi, I just went over the X-Cube-SBSFU material and tried to compile the example projects to get an overall picture of this function.The MCU I used is STM32F730I8 and I am using the STM32F7308-DISCO board.As only 64kB flash is available in STM32F730 s...
I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.
Dear all. How secure is STM32 MCUs to prevent hackers from dumping the firmware from the flash memory? I've searched on the internet and on Taobao (like ebay) China and I found there are plenty of companies that claim they can crack and dump the fla...
For example, Im looking at the STM32L073RZT6 This documentation from ST states there is "128‑bit AES hardware encryption".https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/brochure/6c/48/c0/f1/bb/35/4a/b4/brstm32ulp.pdf...
Is there a list of STM32 based Mbed supported MCUs that have hardware encryption?I'm looking for the cheapest options.Many thanks
The reference manual gives a brief description but how do you actually implement it?I'm using an STM32F437 which includes a cryptographic accelerator so I'm not looking to use the Cryptographic Library.Any documentation, tutorial, example code or any...
Hi,In my company we are currenlty looking at integrate the crypto lib.I have created a small STM32 IDE project to test the crypto lib provided by ST. I am using the Nucleo STM32413. The whole project compiles and I can succesfully call AccHw_AES_CFB_...
Hello,When the RDP level 1 protection option bytes is set and the boot adress is set in the user flash memory, what are the debugger protections ? Which parts of the microcontroller still remain available via the JTAG debug port or the SWD debug po...
