Digital signature with extra info

In a system like PGP/GPG, add extra authentication info from a certifier into the signature and you will be infringing on this patent, no matter how your crypto algorithms work. Although the main claim after examination is very long and detailed, it is just as broad as it was before examination, because most of the added information is redundant. It follows from the problem that is owned by this patentee.
