        GnuPG
    </h2>

    <p>
        To configure <a href="https://gnupg.org">GnuPG</a>
        to use <span class="brand">keys.openpgp.org</span> as keyserver,
        add this line to your <tt>gpg.conf</tt> file:
        <blockquote>
            keyserver hkps://keys.openpgp.org
        </blockquote>
    </p>

    <h4 id="gnupg-retrieve"><a href="#gnupg-retrieve">Retrieving keys</a></h4>
    <ul>
        <li>
            To locate the key of a user, by email address:
            <blockquote>gpg --auto-key-locate keyserver --locate-keys user@example.net</blockquote>
        </li>
        <li>To refresh all your keys (e.g. new revocation certificates and subkeys):
            <blockquote>gpg --refresh-keys</blockquote>
        </li>
    </ul>

    <h4 id="gnupg-upload"><a href="#gnupg-upload">Uploading your key</a></h4>
    <p>
        Keys can be uploaded with GnuPG's <tt>--send-keys</tt> command, but
        identity information can't be verified that way to make the key
        searchable by e-mail address (<a href="/about">what's that?</a>).
    </p>

    <ul>
        <li>
            You can try this shortcut for uploading your key, which outputs
            a direct link to the verification page:
            <blockquote>
                gpg --export your_address@example.net | curl -T - {{ base_uri }}
            </blockquote>
        </li>
        <li>
            Alternatively, you can export them to a file and enter that into the
            <a href="/upload" target="_blank">upload</a> page:
            <blockquote>
                gpg --export your_address@example.net &gt; my_key.pub
            </blockquote>
        </li>
    </ul>

    <h4 id="gnupg-troubleshooting"><a href="#gnupg-troubleshooting">Troubleshooting</a></h4>
    <ul>
        <li>
            Some old <tt>~/gnupg/dirmngr.conf</tt> files contain a line like this:
            <blockquote>
                hkp-cacert ~/.gnupg/sks-keyservers.netCA.pem
            </blockquote>
            <p>
                This configuration is no longer necessary,
                but prevents regular certificates from working.
                It is recommended to simply remove this line from the configuration.
            </p>
        </li>
        <li>
            While refreshing keys, you may see errors like the following:
            <blockquote>gpg: key A2604867523C7ED8: no user ID</blockquote>
            This is a <a href="https://dev.gnupg.org/T4393" target="_blank">known problem in GnuPG</a>.
            We are working with the GnuPG team to resolve this issue.
        </li>
    </ul>
