Having me do a clean write up of the new EVP interface defenitely 
is a good think. Because my confusion over the code grows by the
minute.

Ok, here is another question. If nobody knows then it will be removed
from the interface and I hope something will crash later on to 
show that it should have been included.

 - What is the function of the 'required_pkey_type' member in the EVP_MD
   structure and the multiple PKEY subtypes?
   their aim seems to be to ensure that only a certain combinations of
   MDs and asym-ciphers are valid (those that have NID). But this
   seems limiting to me and should be handled by the application calling 
   the function.
