I am facing the same issue.
since i don't have arduino nano, can you sent me a print screen of the working examples. I need to verify the output in order to push to code into the library.
i solved this issue with this solution, https://forum.arduino.cc/index.php?topic=299928.0
I use Arduino IDE 1.8.3 and Arduino NANO, PROGMEM should be const:
sha256.cpp:3: error: variable 'sha256K' must be const in order to be put into read-only section by means of '__attribute__((progmem))'
