let’s assume you are a privacy enthusiast, Cypherpunk etc. and want to be sure that nobody can tamper with your web page articles or in case you made an invention you published and someone else stole your content and claims he is the author.
With mfv it is hopefully impossible for third parties to tamper with your web content.
For my little website oc2mx.net I have also included in the html source
the page filename and my domain, so that this information is also included
in the hashes and timestamps.
