How to add STM32 cryptographic library in a project using kiel IDE??

When using X-cube-sbsfu, why is swap area size constrained to be at least equal to the size of the largest flash sector? Is there a way to modify SBSFU to work with a smaller swap area?

On STM32F746, largest sector is 256K and total flash size is 1M. This means that 1/4th of our flash is lost to the swap area. As a result, we do not have enough flash memory left to implement the dual image variant. We are now trying to optimize the ...

Problem with reloading option bytes - STM32L452RE

I want to modify option bytes to set up readout protection. I am programming this device with my own programming tool (UART+BOOT0+RESET pin). Programming works fine using bootloader protocol. Setting readout protection doesn't. After setting it up it...

How to make X-CUBE-CRYPTOLIB V3.1.0 to perform AES-192 encryption compatible with other online tools?

I am using X-CUBE-CRYPTOLIB V3.1.0 on STM32L0 to perform AES-192 encryption with a 192-bits key and 128-bits IV. Encrypted Data by STM32L0 can be correctly decrypted by STM32L0 using the same library.However, when I copy the encrypted data, key and I...

HI, I'm working with STM32F103R8 on AES .The input key which I enter is not stored properly I tried by simply displaying the key through UART.Here I missed the 13th to 16th elements.This happens only for a 32byte array.

Can anyone help me with this,I have attached the code below.Thanks in Advance

Hi., I'm beginner for atollic true studio. i need to work with SHA- 256 and AES-128 algorithm for Stm32F series plz help me for the development. There is any library availability plz share
