Okay, just to be sure, what does "Asynchronous" mean in ablkcipher or ahash ? Is it related to the fact that crypto operations can be done in multiple steps (e.g.: one set_key + several encrypt chunk operations), or is this something else ?
It gives you the ability to postpone the processing. However it doesn't mean that you have to postpone the processing. For instance, all of our sync software algorithms are also available through the async interface for obvious reasons.
