Hello @stI am taking the reference implementation of the HKDF Algorithm using PSA API in the TFM Application Project and using the following algorithm :PSA_ALG_HKDF(PSA_ALG_SHA_256);I m able to export the output key to the console and am getting an o...
Hello, I am using STM32U585 TFM architecture for one of my project. Which basically is a combined project of 5 internal projects as usual TFM(mentioned below).1. TFM_Appli_NonSecure2. TFM_Appli_Secure3. TFM_Loader_NonSecure4. TFM_Loader_Secure5. TFM_...
Good afternoon,I am trying to encrypt some data using the AES peripheral and compare the results to the same operation in python and .NET. The cipher text output from the operation on the STM32 is different than that of the other two languages.The co...
Reference: STM32CubeExpansion_Crypto_V4..1.0, MCU: STM32G474REThe cmox_ecdsa_verify(...) function is failing with a fault code of 0x6c706, which is not contained within cmox_ecc_retvals.h header file. All arguments to the cmox_ecdsa_verify(...) funct...
Hi I have the project with the chip STSAFE_A110I don't need to development the application I just need to confirm the hardware is ok, for example, obtained the sn of the chip is successfully or other wayI don't want to add the stsw-safea1-mw to my pr...
Hello,I have a project created with STM32CubeIDE that includes FreeRTOS.A Black Duck vulnerability scan was made on this project and a single vulnerability (CVE-2021-3420) was detected.This vulnerability describes a flaw in Newlib 3.3.0 (all versions...
In the X-CUBE-CRYPTOLIB v4.1.0, the documentation say that cmox_cipher_decrypt() accept the CMOX_AESFAST_CFB_DEC_ALGO as algo. But CMOX_AESFAST_CFB_DEC_ALGO is not defined, instead there is a CMOX_AESFAST_CFB_DEC_ALG in cmox_cfb.h.
How do you determine or configure the I2C address of the ST33PHF2XI2C? The data sheet does not explicitly state the devices I2C address, nor as far as I have read, described how to configure the address with strapping options either. Is there another...
HiI'm using the SBSFU example for the STM32U5 microcontroller. After an intrusion, the board enters a locked state. Is there a way to receive a notification when an intrusion occurs and another when it has ceased, indicating that the board can return...
Hi @Jocelyn RICARD I would like to generate Certificate Signing Request in my STM32H5 board, can i know which library i can use and share any document or example project
