OK. I will bookmark and recommend others do similarly, but I won't try
to fight this battle here.

The overall flow is fine.

Even if that breaks existing fielded implementations? Good.

I'll argue thiese in a later post.

This seems a weird requirement - legality of encryption isn't really a
big problem any more. But I don't currently see a need for encryption
in the core, so I won't argue this just now.

No, it's much harder and slower: see
0.18 ms for RSA verification versus 2.46 ms for DSA verification.
But the big win with RSA over DSA is that the signatures are much
smaller, as Nicko van Someren noted in the Slashdot discussion about it.

Make me security dictator :-)/2
