This is mostly just a note to myself to do what the title says.
Clearly quite a few people care about encrypted communication, as they should. There is a big audience for apps like Signal — people that care that their communications are end-to-end encrypted.
Email is definitely not end-to-end encrypted… unless you very specifically set it up to be. So my questions to research are:
- How practical is it to set up end-to-end encrypted email?
- Doesn’t who receives it also have to be set up for that? How big of a barrier is that? What is the day-to-day practicality for people who run encrypted email?
- What services help with this? What are the costs? How popular are they? How DIY can it be?
- Is there any movement toward large-scale adoption of encrypted email?
