Thank you. Doing something like this had totally slipped my mind. I actually
pass find's output to xargs anyway, so could do something like
find . -not -name '*.gpg' -print0 | xargs -0I{} 'bash -c "gpg {}
&& md5 {} >> hashes"'
This solution now seems, well, very obvious.

Yes I'm aware of this, thanks. (This was why I was going to hash the plaintexts
in the first place.)
