How to correctly implement SHA-2 in C++?

Question

Cryptography

Good day, %username% ! Need your help!
I am a second-year student and the topic of my course work is: "Implementation of the SHA-2 (256,384,512) hash functions in C ++."
As you understand, the level of programming knowledge is rather mediocre in this context, otherwise I would not contact you. It so happened that they did not teach us "Programming of crypto-primitives" and other things.
But I am quite clearly aware that there are a lot of different ready-made solutions.
Maybe you can suggest open libraries with ready-made primitives or share your source codes? I will be very grateful to you!

Answer 1

Implementation is very simple, you need to open the text description of the algorithm and write code on it.
The task of learning is to learn how to write code yourself, and not to give out ready-made solutions for your work.
