Secure communication with GnuPG and E-Mail

How E-Mail with GnuPG could hide when you talk, where you talk from and what you talk about.

or in technical terms:

E-Mail with perfect forward security, hidden subject and masked date using GnuPG and better frontends.

Update 2018: Some of these ideas are becoming real and widespread now with pΞp (pretty-easy-privacy) and the autocrypt-standard.

If you regularly read my articles, you’ll know that I’m a proponent of connecting over Freenet to regain confidential and pseudonymous communication.

Here I want to show how it would be possible to use E-Mail with GnuPG to get close to the confidentiality of Freenet friend-to-friend communication, because we have the tech (among the most heavily scrutinized and well-tested technology we use today) and we have the infrastructure. All it requires are more intelligent E-Mail clients. Better UI which makes the right thing easy.
