Basic GPG/PGP keys creation and deployment tutorial

How to create a GPG key pair? How to publish a GPG public key? Here is a short and handy guide 🙂

PGP: stands for Pretty Good Privacy and it was created by Symantec

GPG: stands for GNU Privacy Guard, an alternative to Symantec’s official PGP software

First of all install and test it:

$ sudo apt install pgpgpg
$ gpg --list-keys

Let’s now create our keys running the wizard and filling the requested information:

$ gpg --full-gen-key

During the keys generation, you will be asked to insert your secret passphrase, DO NOT lose it.

Generate now the revocation certificate in case something happens such as your private key is compromised:

$ gpg --output revoke.asc --gen-revoke <>

Store the output file in a safe place (a pendrive or print it).

Now we are ready to deploy our public key on a key server.

Export the PUBLIC key with the following command:

$ gpg --output public.pgp --armor --export <>

You can now upload the PUBLIC key file, for example, at the Symantec server:

With this last command we export the PRIVATE key that MUST NOT be shared with anyone:

gpg --output private.pgp --armor --export-secret-key <>
