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,
C:\Users\jonis\Documents\Arduino\libraries\Sha/sha256_config.h:26:21: fatal error: avr/io.h: No such file or directory
exit status 1
I just need to hash using SHA256, not HMAC.
