Make sure you (and/or your database server) are in a country where encryption is not illegal-it still is in some countries.
In order to create and manage PGP keys, you also need the well-known GnuPG command-line utility, which is available on practically all distributions.
pgcrypto is part of the contrib collection. Starting from version 10, on Debian and Ubuntu is part of the main postgresql-10 server package, while in previous versions there was a separate package, for example, postgresql-contrib-9.6.
Install it on the database in which you want to use it, following the Adding an external module to PostgreSQL recipe from Chapter 3, Configuration.
You also need to have PGP keys set up:
pguser@laptop:~$ gpg --gen-key
