Correct digest for SHA-1!

And correct digest for SHA-256!

Try again! ;-)

It _shouldn't_ happen. It is (I think) caused by the reader thread
trying to read after the the device has been closed. My multithread
Python fu needs improvement.

But the important thing is that you were able to download the HW design
from the Cryptech repo, set up the dev and test environment, build the
FPGA design and download it. And the run hash operations on our own HW.
Not bad me thinks.
