STM32 MCUs Security

Can I use CubeExpansion_Crypto_V3.1.0 with the STM32WB series?

Hi,Before I try this out is it possible to use this library to Decrypt AES-GCM 256 on a WB series mcu?

How can I set STM32F427 SPI CRC Initial value?

If the SPI_InitStruct.SPI_CRCPolynomial = 0x1021; I would like to set the SPI CRC initial value to 0xFFFF; I can NOT find the register, can someone tell me the details?

Activation of Readout protection from user application

Hi,I am trying to implement readout protection on my stm32f427VG. I want to apply Read protection Level 2 from the user application or bootloader code in the flash. My custom bootloader resides in flash at address 0x00000000.

Use of STM32L4 HAL_CRYP hardware in LORAWAN

I've tried to find an example code of use of crypto harware accelerator in LORAWAN but i haven't been able to find any . Does someone have an example expecially concerning the use of AES CMAC?Regards

What is the correct sequence to remove read protection (RDP level 1 -> RDP level 0) using bootloader over SPI-bus?

I working with the STM32F446-microcontroller and I need to upgrade firmware and change the option bytes on it using the built-in bootloader (en.CD00167594.pdf, AN2606) using SPI-bus (en.DM00081379.pdf, AN4286). I am able to successfully modify all op...
