Hello,
Does any body know if there is a free source code for SHA-256 implementation in C for STM32 implementable in Keil?
Thank you. Your description is good for understanding basic concept of Hash. But I still need to know a standard way of adding a key to a data maybe like method used in HMAC-SHA-256.
What part of the use of Google is it that you don't understand?
Right now, you are a danger to yourself and your surroundings because you are refusing to invest time trying to understand exactly what you should do - and how you should do it.
Hi Hamed Adldoost,
Could you please describe the method used in HMAC-SHA-256? Since you already know that.
You know the method, but you want a more standard method. If this is the case, you would have to describe the method first.
