Some minor suggestions:

* The naming of BLOCK_SIZE and block_len in hashSignedDataBlock seems
misleading to me, maybe CHUNK_SIZE and block_len?

* The method hashSignedDataBlock could probably be replaced by a static
function taking the stream and the handler? This should give the
compiler more optimization possibilities than if it is visible in other
translation units.

* I think the while loop within could become a for loop for better
readability with the case reduced to computing the number of bytes to
read instead of two separate calls to doGetChars and updateHash.
