Not related to GPG, you might also be interested in https://www.pki.dfn.de/zeitstempeldienst/ which is AFAIK the only free "trustworthy" (meaning it is run by a organisation, not a test server and has some sort of usage terms) RFC 3161 timestamp server. I use it with PDF signatures (using a certificate issued to me by the government http://www.buergerkarte.at/), because it is a lot easier to show average people how Acrobat Reader says everything is OK than explaining GPG. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
