This is good news, so the newer keys have unspoofable fingerprints while
the older RSA keys do not.. Is there any way to get GPG give output (and
do matches) for a RSA key in v4 form?

The person who gave this information to me said it was essential to
specify both the fingerprint and the size for the RSA keys, but if there
is no way to ask GPG to do matches with both pieces of information then
there is not much point in storing it.

Our fingerprints are unique and we can deal with assuring that - if they
are not unique then how can I deal with it? There is no other way to
specify a key than by fingerprint, right?
