If you read this: https://pressfreedomfoundation.org/encryption-works carefully, it may explain what was Miranda doing in London. It wasn't about sharing docs, but rather setting up Tail, I would think. Any docs he had on him were rather there only to misguide. I am rubish with IT myself and only recenly, due to the necessity, have started learning all this & have been trying to change the ways I communicate and although every day I feel I begin to understand it, I still confuse things with keys, certificates and, if I be am honest am not sure whether people are recieveing my mail when I manage to encrypt it. Also, i dunno why, but I assumed that it will be safer if record all passwords on a paper... There is too many passwords to be able to remember all of them. How can you handle it? Personally, I think I need proper help with all this as it starts to really frustrate me or simly stop using internet as I am not sure whether I protect myself the right way or whether it works like it should and wird things began to happen both with my laptop and in my life.
