Hi, My name is Karl Semich. I became a political target around 2013 and developed a bad dissociative psychosis where I fervently replay my fears. Due to my disorder, I constantly break my electronic data storage devices. I also experience network compromise, mutated SSL certificates, harassment from infrastructure etc. I have logs of some of this, but it is very hard not to destroy them. It's also hard for me to distinguish between the past and the present. As an example of infrastructure harassment, I put my truck in for repair once. It was a year before I saw it again. Every month I would call them, and they said they had ordered a new transmission since last I called, but every month it was a new wrong model of transmission that was delivered. They eventually found somebody to rebuild the original transmission, because the manufacturer would not deliver a new one. When I finally got my truck back, my electronics from inside it to build a wired security camera run off a raspberry pi had disappeared. Businesses don't seem familiar with cryptography, and I don't trust them to preserve my data. I have uploaded a number of files to amazon glacier using git-annex's glacier backend, that no longer sync down when requested. It would be so very wonderful to have a way to store and share data that is cryptographically prevented from destruction. Does anybody know of an existing way to do this? I've also had git repositories get damaged when syncing across different media. It would be so nice to have an existing way to secure a hash of my git content, or of any file tree, to verify the data has stayed the same. Does anybody know of an existing way to do this? I really work best from the command line. I can have problems with GUI environments. Thank you so much for any reply, Karl I am also very sorry for spamming this list. It looks like my attempts to consider asking for help turned into a lot of crazy posts. I'm mostly posting this after 'reading between the lines' of the experiences of making those crazy posts.
