Yes, I think you're right.  The reason we did it this way was that
we're expecting to add more modes, such as 'dynamic' and/or 'canned-
dynamic' etc.

But I don't see a reason we couldn't just register them all and have
the user choose using the algorithm names, especially if that's the way
crypto users expect things to work.

Thanks,
