In-reply-to > @eaplmx you are referring to a cryptography sharing scheme known as Shamir's Secret Sharing. I have a Golang implementation running for my own use.

It is actually JS based. I think Golang is simply used to fetch the needed resources, and then generate the final page, which can be used offline. I have secrets split in 6 chunks, with a threshold of 3, and I gave each to wife, children, mum and dad in-law. That ought to cover for any accident—unless we are all in the same event, which is highly unlikely.
