The history behind this is that the crypto layer has used chaining way before generic chaining was invented. When the generic code was added I tried to convert crypto over to that, however, that failed because generic chaining was not ported to every architecture.
So that's why the crypto layer still retains its own chaining.

I suppose we should ask Jens whether he thinks this is worth adding an interface over?
