Is this line needed? If not, please remove instead of comment-out.

Please define const variable for the magic number '16'.

We had better have
   const size_t Sha1HashSize = 20;
here or SHA1.h.

Removed.

Defined "nonceSize".

Defined a constant inside this function for now. Added a FIXME comment to tell it really should be moved to SHA1.h.
