This tutorial will walk you through typical GPG workflow: generating, signing, trusting, renewing and backing up keys. Instead of long explanations it just shows what happens in practice on test data.
Important: older GPG versions behave significantly different and use
different formats for storing data. This tutorial was tested with GPG
2.2.4; you can check your version using gpg --version.

| Vagrantfile | |
| ``` | |
| # -*- mode: ruby -*- | |

| # Bash has a nice feature called "directory stack" - sort of "location history": | |
| # https://www.gnu.org/software/bash/manual/html_node/The-Directory-Stack.html | |
| # However, I find the built-in commands not really convenient. This makes the | |
| # directory stack available as a sort of extension to `cd` interface. | |
| function _cd { | |
| # typing just `_cd` will take you $HOME ;) | |
