| <p>It is essential that you verify the integrity of the downloaded files using the PGP and SHA512 signatures. |
| Please read <a class="externalLink" href="https://httpd.apache.org/dev/verification.html">Verifying Apache HTTP Server Releases</a> for more |
| information on why you should verify our releases.</p> |
| <p>The PGP signatures can be verified using PGP or GPG. First download the |
| <a class="externalLink" href="https://www.apache.org/dist/logging/KEYS">KEYS</a> as well as the asc signature file for the relevant distribution. |
| Make sure you get these files from the <a class="externalLink" href="https://www.apache.org/dist/logging/">main distribution directory</a>, rather |
| than from a mirror. Then verify the signatures using</p> |
| |
| <div class="source"><pre class="prettyprint"><code>gpg --import KEYS |
| gpg --verify apache-log4j-2.23.1-bin.zip.asc |
| </code></pre></div> |
| <p>Alternatively, you can verify the SHA512 signature on the files. A Unix program called sha or sha512sum is included |
| in many Unix distributions.</p><section> |
