            <p>
                It is essential that you verify the integrity of the downloaded files using the PGP and SHA2 signatures.
                Please read
                <a href="https://httpd.apache.org/dev/verification.html">Verifying Apache HTTP Server Releases</a>
                for more information on why you should verify our releases. This page provides detailed instructions
                which you can use for POI artifacts.
            </p>
            <p>
                The PGP signatures can be verified using PGP or GPG. First download the
                <a href="https://www.apache.org/dist/poi/KEYS">KEYS</a>
                file as well as the .asc signature files for the relevant release packages. Make sure you get these
                files from the main distribution directory, rather than from a mirror.
                Then <a href="https://www.apache.org/info/verification.html">verify the signatures</a>.
            </p>
            <p>Batch check of all distribution files:</p>
            <source>
                find . -name "*.sha256" -type f -execdir sha256sum -c {} \;
                find . -name "*.sha512" -type f -execdir sha512sum -c {} \;
