rpm: what does the release number in `gpg-pubkey-<verstion>-<release>` stands for?
<p><em>(cross posting unanswered <a href="http://superuser.com/questions/173438/rpm-what-does-the-release-number-in-gpg-pubkey-verstion-release-stands-for">question on superuser.com</a>)</em></p>

<p>GnuPG public keys that are imported into the RPM keyring with:</p>
<pre><code>rpm --import PUBKEY_FILE
</code></pre>
<p>can be queried with</p>
<pre><code>rpm -q gpg-pubkey-<key-id>
</code></pre>
<p>For example the CentOS4 key:</p>
<pre><code>pub 1024D/443E1821 2005-02-25 CentOS-4 key <centos-4key@centos.org>
Key fingerprint = 31EA 27E5 6F79 0C18 AD79 18DF A53D 0BAB 443E 1821
sub 2048g/06870DBC 2005-02-25 [expires: 2015-02-23]
</code></pre>
<p>can be queried with</p>
<pre><code>rpm -q gpg-pubkey-443e1821
</code></pre>
<p>and the result is:</p>
<pre><code>gpg-pubkey-443e1821-421f218f
</code></pre>
<p>The RPM's version number <code>443e1821</code> corresponds to the key id <code>0x443e1821</code> but <strong>what the release number <code>421f218f</code> stands for?</strong></p>
