SHA256 and HMAC-SHA256

I'm new to arduino and programming,
I want to use SHA256 and HMAC-SHA256 on my arduino uno.

Please share correct library file for SHA256.

I tried using libraries from GIT_HUB but got compiling error.

If you want help trying to get the libraries you found, you can post a link to the repository and the full text of the error messages you got.
