That should be SHA256Digest, not SHA156Digest.

   Anyway, I was concerned that maybe the raw digest was in error as
the output above has been massaged into a character representation for
an ostream. Perhaps all those excess zeroes were in memory but were
neatly removed when going out ostream...

   It looks good here.
