I had trouble finding this with Google-fu but was there not discussion a while back of a format for stringifying file content and encrypting it for printing and dead-tree archiving in a safe or whatnot? I am having trouble finding any info about. I found OllyDbg Paperback, but I am not sure that is what I was looking for. Anyone remember?

I am curious if someone could "paper up" something like PGP to be stored in a safe, if the format I vaguely recall did not go that far.
