I am just getting my feet wet with all this. I have been using and exploring tails, but for some reason can't get it to work with persistence. I am not asking for help just yet, I like to be able to figure these things out on my own; it's fun and allows me to better understand things. But I did want to ask: If, for whatever reason, I can't get tails to work with persistence, what is another way to save things like keys safely?
You can create an encrypted volume on another device by using this method:
