I was the one who introduced it, and I chose bits instead of 
bytes because I didn't want to exclude the possibility that there 
are hashing algos that have a block size not divisible by 8. The 
algorithms are usually described in terms of bits, not bytes, so 
it's not unconceivable that such hash functions exist, though I 
don't know any. (Of course, HMAC wouldn't work with those, but 
that doesn't mean that other algorithms couldn't.)

I'd suggest you change `blockSize` to the number of bits, and 
introduce an enum `blockSizeInBytes` for internal use.
