In these days, I am thinking a lot about encryption and integrity of communication channels. Every mail I send, is automatically signed via my GPG key. I am doing this, not only to remind people of the fact, that GPG/PGP exists and that they should use it. I am primarily doing it for its main purpose, to give the recipients the possibility to verify the integrity of the mail and that it was really sent by myself. Today I thought… well, as I give the recipients of my mails this option, why shouldn’t I give this option also to the readers of my blog?
