In fact, I believe there is no such thing as "signing the whole binary
blob". When you use something like gpg --sign, what is actually signed with
a public key signature algorithm is a hash of the content anyway. Thus,
assuming you use the same hash algorithm as you would have instructed gpg
to use (I think the default is SHA512 these days), there isn't any real
difference between signing the content directly, and signing a hash of the
