Posted on March 14, 2016 at 18:01I'm using the CRC unit on the STM32L486. In the reference manual it states that:''CRC computation is done on the whole 32-bit dataword or byte by byte depending on the format of the data being written.''However, late...
Posted on March 01, 2016 at 13:39Hi, My problem is this, i have a product that have in the pages 0-3 a bootloader, and the RDP is state ON to protect my code, then the application code (120KB). All works fine and with this bootloader i can change th...
Posted on February 16, 2016 at 16:01 Hi! I'm using the X-CUBE-CRYPTOLIB (AES-256-ECB) on the STM3220 devboard using System Workbench (GCC) with no luck. I set the config.h file (tried every permutation nearly), my project compiles success...
Posted on January 05, 2016 at 08:15Just noticed this library called X-Cube-Cryptolib. Quick question is , if i use the HW accelerated version of the lib, is it safe to make calls to the library from different RTOS threads considering they will be ca...
Posted on November 11, 2015 at 18:11I'm trying to install the STM32Cube Cryptographic Library v3.0.0 on a fresh STM32CubMX install, version 4.11.0, under Windows 7. Installation fails with a message that ''This Package version is not managed on this...
Posted on October 30, 2015 at 20:08Hi. I want to make SSI protocol with SPI peripheral on STM32F3 series. Also want to use DMA for Tx. There is a hardware CRC calculation unit, which calculate CRC above all data and is attached as last byte (in my c...
Posted on October 06, 2015 at 12:24Hi all, Anyone knows why the following code is not disabling the flash memory readout protection? It is being executed on a STM32F103 microcontroller.FLASH_Unlock(); FLASH_ReadOutProtection(DISABLE); FLASH_UserOp...
Posted on November 09, 2013 at 13:03Hello Everyone,Does anybody know, how exactly to use STs crypto library (V2.0.6 for STM32F427) such that it behaves / is compatible with openssl?i.e. generating an encrypted file via:openssl enc $encryption -p -e ...
Posted on June 14, 2015 at 15:15Hi,I'm developing on the stm32f207 with the M3_CryptoFW_RngHW_2_0_6.libI would like to use the sha-1 from lib but from some reason I do not get the correct result.Here is my test...My input buffer is 8 bytes: 1,2,3,4,...
Posted on May 19, 2015 at 12:47I am trying out some examples of the crypto library from ST, but its not working the way it should.If I try the AES-CBC192 examples on a STM32F107 (STM3210C eval board),I can verify that the encrypted cipher text is co...
