1) I occasionally use it to send secrets (password, certificates, private keys) to people when I can't meet them in person. 2) I share a file-based password manager with other people, that is basically just a collection of PGP-encrypted files with multiple recipients (managed using "pass"). 3) I sign git tags, so that people know I have made the release. 4) I rely on the fact that all Ubuntu packages are signed and I will not accidentally install a package from an unknown source. 5) I have encrypted backups.
