We should be using better hashes than MD5, these days. But yes, possibly
just signing the +CONTENTS file would do the trick. On the other hand,
it might be nice to have a generic way of signing archives--I've put in
a use case for that.

Well, let's do a security analysis of it. It would be nice to avoid
having to ship around two separate files all the time.
