No please do not expose the struct public_key crap to the new
API.  The key should be completely opaque to entities outside
of the algorithm.  So make it raw and read out the MPIs from
it.

The contents of the function must go into the algorithm setkey
function, not the crypto API.  So RSA would read out however
many MPIs it needs and verify it, and so on.

Cheers,
