How to get a public key registered with a key server

Prerequisites

You need a personal or company GPG key. If you don't have one, this explains how to generate a GPG key.

Export your public key

gpg --export --armor john@example.com > john_doe.pub

-----BEGIN PGP PUBLIC KEY BLOCK-----
mQGiBEm7B54RBADhXaYmvUdBoyt5wAi......=vEm7B54RBADh9dmP
-----END PGP PUBLIC KEY BLOCK-----

About the arguments:

--export Export the public key information of the key belonging to john@example.com
--armor Create a base64 encoded ascii string rather than using a binary format
john@example.com The key id to export
> john_doe.pub Save the output into this file

gpg --keyid-format LONG --list-keys john@example.com
pub   rsa4096/ABCDEF0123456789 2018-01-01 [SCEA] [expires: 2021-01-01]
      ABCDEF0123456789ABCDEF0123456789
uid              [ ultimate ] John Doe <john@example.com>

This shows the 16-byte Key-ID right after the key-type and key-size. In this example it's the highlighted part of this line:

pub rsa4096/ABCDEF0123456789 2018-01-01 [SCEA] [expires: 2021-01-01] Offboard Diagnostic Information System -ODIS- 2...

The next step is to use this Key-ID to send it to the keyserver, in our case the MIT one. Allows for the configuration and adaptation of Electronic

gpg --keyserver keyserver.ubuntu.com --send-keys ABCDEF0123456789
