I like the idea of a registry for crypto functions similar to the one for
Unicode codecs.  Codecs have a flat namespace; do we want find_alg('MD5') or
find_alg('MD5', type='hash') or find_hash_alg('MD5')?  In other words, do we
have to know ahead of time that MD5 is a hash algorithm, or can we get an
instance first without knowing what the algorithm actually does?

Does someone want to write a proposed interface for the registration and
search functions, and the config file?
