That's quite a bummer. I finally managed to convince someone to use gpg and now I learn that this just makes sure your emails will be read/analyzed by anyone who has an interest in it in the future.
- geofft 10y ago"anyone who has an interest in it in the future" is a very vague term. I'm confident lots of things will happen in crypto centuries after I die, but that's not in my threat model.
- cJ0th 10y agoNeither do I care about what happens in a couple of centuries. My main worry is that in a somewhat foreseeable future data of electronic communications can be used to construct a model of how a society of interest works to a degree useful enough to attack/control it. So it isn't necessarily about what I am communicating or to whom I talk but the fact that it seems impossible for society as a whole the hide the details of its functioning. I viewed pgp/gpg as a tool that could counter this. Convincing people to use it would've been an uphill battle but there would have been a slim chance of succeeding to a useful degree.
