Herbert, Could you please clarify?
In the earlier code we had a async_request which is now replaced by
crypto_async_request. Do you want a new async_request to be used?
Do you think we shouldn't be setting the members of the
crypto_ahash_request directly, but use some other interface to do the
same for us?
