with all its problems; look just a little bit into the future;
when I sign a document today, the certificate I sign this document maybe
valid till the end of next year (end of the year 2017);
let us think this is an important document; and let us think you were a
young boy now;
in case the software still exists in the next 50 years, the diagnosis if
the document has been modified is easy, but ...
how would you be able to verify that this document hasn't been signed by a
certificate that had been revoked when you are an old man?
