Or 4): Drop the micalg parameter. This will make one-pass processing
impossible, but I doubt that it's worth the trouble (unless the
theoretical possibility of one-pass processing is required by some
MIME standard). Future revisions of the OpenPGP message standard
might specify additional hash algorithms (which might even require
some parameters); OpenPGP implementators might want to use proprietary
algorithms, and so on. Synchronizing OpenPGP-MIME with these
developments is not very complicated, but I think the benifit of
having a micalg parameter is even too small for that.
