A software (and optionally, hardware) project for automating the creation of offsite backups on flash drives. The idea is that you have a large-ish flash drive on your keyring; when you take your keys out of your pocket, plug the flash drive into the device. The specific use case is a hanging key holder with a RasPi inside of it. The files in the backup script are automatically encrypted and copied onto the flash drive. That way, if anything happens while you're out and about you have the latest and greatest copies of the files already with you.

restic is a backup program that is fast, efficient and secure. It supports the three major operating systems (Linux, macOS, Windows) and a few smaller ones (FreeBSD, OpenBSD).

A shell script that lets you copy Git repos up to the IPFS network.

A utility that makes it easy to back up your OpenPGP keys on dead trees by extracting the secret bytes and printing them out.
