No thanks. I've been playing around with PGP a bit, or should I say GPG/gnuPG to be correct? After reading some messages in a Eudora newsgroup I decided to check out the plugin again and reinstall gnuPG - I had it installed before but never really used it.
As of today, I think I'll be signing my outgoing messages so people that receive them can verify their authenticity. Encrypting mail is not yet an option as no one I know uses PGP/GPG let alone knows anything about it as far as I'm aware.
Of course you can say that there is no need at all to sign, let alone encrypt regular mail because I don't have anything to hide, on the other hand... what's the problem if I do? Why should anyone be upset that I encrypt and protect my mail? It doesn't affect you, does it, unless maybe you were interested in the content of it from the beginning :p

I know quite a lot about PGP etc but don't see the point. I just don't use email enough or for anything important enough to bother. I just work on the (correct) assumption that anything I send via email is public and keep anything important to a phone call *shrug*.
