Sorry, you're right.

It's already abusing the shash API, this doesn't change that, except where it
gets the data from.

I can have a go at conversion to ahash, but that will have to be a separate
patch set as it isn't trivial.  The problem is that the current code just
assumes it can push bits into the hash as it gets them - this is not possible
with ahash.
