I seem to be massively misreading ECB for CBC and vice versa.

The test code that I wrote several weeks ago that I thought let me use CBC
for decryption without an AlgorithmParameters. . . .
I double checked. I misread. It was ECB.

My confusion over the Alice/Bob Key Agreement code is what tipped me off.
I was certain that it also used CBC. And I was certain that I copied it.

I'm still, like David, bothered by the non-WORA aspect.
I assumed that the purpose of different providers (and I think I read this
somewhere!) was that one provider might have a higher security rating,
or faster algorithms, or provide a wider variety of algorithms.
I didn't think that they were allowed to give different answers to the
same question. Users will be surprised once they have multiple providers.
