Learn GPG by doing

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.

# Synchronize history between bash sessions
#
# Make history from other terminals available to the current one. However,
# don't mix all histories together - make sure that *all* commands from the
# current session are on top of its history, so that pressing up arrow will
# give you most recent command from this session, not from any session.
#
# Since history is saved on each prompt, this additionally protects it from
# terminal crashes.

# "cd with history"
#
# 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 ;)
