I know that I can simply make my own private certificate authority that only I and my family trust. But is there some public provider like letsencrypt that is in a free-er part of the world than the US?
That’s a very important point to consider. Unless you remove the battery, you shouldn’t use it as a server. If you still do, store it in a metal bowl or so and put it somewhere where the heat of the bowl itself cannot start a fire. And make sure that your smoke detectors are still working and not expired. Then, be aware that if the battery explodes, your apartment fills with biting toxic smoke within minutes, and that can happen in the middle of the night. So keep some clothes ready at the door that you can wear when fleeing the apartment.



For me it’s like this: some art I really like, and if there is no good alternative I will still enjoy it even if the artist may be a criminal or promoting hate. If I can avoid the art somehow, then I’ll do that.
