I added a new "Encryption has a shelf life" section to the Caveats section of #Spritely Golem's writeup. It's an important point I hadn't called out previously! https://gitlab.com/spritely/golem/blob/master/README.org
> Encryption has a shelf life. In general, secure ciphers from about 15 years ago aren’t secure today, so it’s possible that chunks that are currently only readable by intended recipients can eventually be read by anyone who gets their hands on them. [...]
@cwebber indeed : it's in the end not a technical problem (it take x years to crack the cypher, with machines or... waiting) but a political one, where humans collectively have to ensure a structure of trust where they still can think and communicate ...
democracy won't be solved by technical trick, but yep, technology can be a tool to help and to think about it :D
@mikegerwitz A good set of comments to which I don't honestly have a great reply. My crypto-math-fu is pretty weak here, but the observation of things weakening is partly based on warnings from more cryptographically astute people I know warning of such and also that so many cipher recommendations of yesteryear *have* weakened. But it's hard to tell if I'm over or under cautioning :)
That said if you wanted to compose ciphers, you could set the es= parameter to something that knows to do that
@cwebber I can highly recommend MC Frontalot's "Secrets from the future" for a near-perfect and entertaining musical performance of this argument. :)
