I think the term «signing» leads to confusion, too. When I receive a
signed statement from a good friend, I have no chance to prove whether
he signed or not. And proving if something was added after he signed it
is even more difficult. But as far as I know this is all possible with
an OpenPGP signature.

So are there analogies that can easily explain what signing does?
