Posted on February 14, 2018 at 18:39Hy.I would like to download the crypto library. When I click the request software button, a form shows up. I fill the form correctly, but nothing happens, I cannot download the software.I really need the library. ...
Posted on August 04, 2014 at 10:47 Hi, I created a C# class which calculates the CRC32 checksum exactly like the STM This may be useful to others: using System; using System.Collections.Generic; using System.Linq; using ...
Posted on February 01, 2018 at 14:46Hi.I'm using an RSA cryptographic library and I have a big issue with the verification process.ST crypto library for RSA has a 'standard' module, message, key pairs and signatures in its main program.I need to use...
Posted on January 25, 2018 at 06:42I am using ♯, where I tried to calculate the 32- bit CRC of my flash using ♯ register.How I can ensure if the CRC calculation of my flash is correct.CRC Configuration I used is :hcrc.Instance = CRC;hcrc.Init.Defaul...
Posted on January 17, 2018 at 10:52Hello everyoneI have some trouble with the CRC unit on my STM32F407 MCU.Before each time I am going to use it to calculate a checksum, I reset it and after doing so I double check that the CRC data register (CRC_DR...
Posted on January 26, 2018 at 09:27Hi,I'm using AES CCM algorithm from X-CUBE-CRYPTOLIB (STM32AccHwCryptoV3.1.0_L4_KEIL_otslsm1elfspf.lib) in sensitive real time system and unfortunelaty it does not fit our time requirement. We would like to investi...
Posted on January 24, 2018 at 15:19Hi,we are facing troubles with the readout Protection on the STM32L0: when you secure the chip and then want to do a firmware update, the Settings and serial numbers in EEPROM also are erased. Can we somehow protec...
Posted on January 19, 2018 at 11:55Hello friends.I created CRC calculator, but I don't know, how to compare results.My input data:uint32_t data[16] = { 0x1234, 0x456, 0x78, 0x09, 0x10, 0x100, 0x1000, 0x01, 0x54, 0x35, 0x98, 0x2432,...
Posted on January 10, 2018 at 14:51 Hi there, I wrote a serial protocol to exchange data between MCU and a PC. This protocol provides a checksum to verify data integrity. At the moment I use a simple sum of each byte but I think that the...
Posted on January 09, 2018 at 14:27HelloI would like to use the crypto lib with gcc (eclipse/ system workbench).The compiler returns this:error: xxx.elf uses VFP register arguments, libSTM32CryptographicV3.0.0_CM4_GCC_ot.a(crypto.o) does not.I'm not...
