SHA256 lib that works?

Is there any SHA256 lib that works in current version of Arduino? (1.6.7)
I found a lot of libs, but none worked. The last that I’ve try is one year since last update, GitHub - spaniakos/Cryptosuite: Cryptographic suite for Arduino & RPi (SHA, HMAC-SHA) but when I try to compile the example sha256test, got this error:

In file included from C:\Users\jonis\Documents\Arduino\libraries\Sha/sha256.h:4:0,

from C:\Users\jonis\Documents\Arduino\libraries\Sha\examples\sha256test\sha256test.pde:1:

C:\Users\jonis\Documents\Arduino\libraries\Sha/sha256_config.h:26:21: fatal error: avr/io.h: No such file or directory

#include <avr/io.h>


compilation terminated.

exit status 1

I just need to hash using SHA256, not HMAC.

What Arduino are you compiling for?

Remove/comment the #include <avr/io.h> line in sha1_config.h and sha256_config.h.
It is already included from <Arduino.h> on AVR boards and not relevant on other boards.
