<p>Any .crt file is also available via the .pem file extension (which will be served as <code>plain/text</code>). Alternatively, append the .txt extension.</p>
<p>For example:</p>
<ul>
<li>homelab-2024-root.crt becomes homelab-2024-root.pem</li>
<li>homelab-2024-root.crt becomes homelab-2024-root.crt.txt</li>
</ul>
<p>Similarly, .crl files can be viewed as plain text if requested with the query string <code>?txt</code>.</p>
