Assume that you have the power to create a calculation.  What would be
your target: A single message or a CA key? 

I'd go for a CA or other important key.  Here we rely on SHA-1 for
fingerprint calculation and the fingerprint is that piece of
information we almost always use to compare keys. You can't change
