Hi, we all know that kidnappers do publish a picture of their hostage holding up a todays newpaper. The purpose of this is to proof that the victim was alive _after_ a certain point of time. I want to do the opposite. I want to make evidence that I created a document _before_ a certain point of time.
I could use self-darkening ink but that won't be reflected in a JPEG scan and my pen won't make the job that TeX does. I could sign a newspapers home page but that cannot be reproduced at a later point of time to verify the signature. Is there a standard way in GnuPG and in the keyholder infrastructure to accomplish this task? Thanks in advance.
