Age is a public-key encryption system, similar in certain concepts to GnuPG (GPG), but simpler because it isn’t focused on building a web of trust. Homepage: https://github.com/FiloSottile/age Conveniently, Age can use not just its own keypairs, but also a person’s SSH keypairs for encryption and decryption. This is nice because many systems already have authenticated SSH keypairs for each other.

I loaded up this title with buzzwords. The basic idea is that IM systems shouldn’t have to only use the Internet. Why not let them be carried across LoRa radios, USB sticks, local Wifi networks, and yes, the Internet? I’ll first discuss how, and then why. How do set it up I’ve talked about most of the pieces here already: Delta Chat, which is an IM app that uses mail servers (SMTP and IMAP) as transport, and OpenPGP encryption for security.| www.complete.org
“OK,” you’re probably thinking. “John, you talk a lot about things like Gopher and personal radios, and now you want to talk about building a reliable network out of… USB drives?” Well, yes. In fact, I’ve already done it. What is sneakernet? Normally, “sneakernet” is a sort of tongue-in-cheek reference to using disconnected storage to transport data or messages. By “disconnect storage” I mean anything like CD-ROMs, hard drives, SD cards, USB drives, and so forth.| www.complete.org
