Ummm...  Possibly.  Is that how it's used?

Anyway, the problem I have with this is that I want to get that knowledge out
of the asymmetric key in-software public key subtype.  It knows "rsa", "dsa",
"ecdsa", ... because that's all the OIDs tell it.

I guess if I have to, I can stoop to converting "rsa" to "pkcs1pad(rsa, sha1)".

Can you do me a really quick merge?  -rc5 is already out, and I want to get it
to James pronto - plus I have things that are pending on this change being
made.

Oh - and how does the padding template find the algorithm DER encoding string
to use?  I have wondered whether it should be stored in with the hash
algorithm, but it probably makes more sense to keep it with the rsa module.
