It is essential that you verify the integrity of the downloaded files using the PGP and SHA512 signatures. Please read Verifying Apache HTTP Server Releases for more information on why you should verify our releases.
The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the asc signature file for the relevant distribution. Make sure you get these files from the main distribution directory, rather than from a mirror. Then verify the signatures using
gpg --import KEYS gpg --verify apache-log4j-2.13.2-bin.tar.gz.asc
Apache Log4j 2.13.2 is signed by Ralph Goers (B3D8E1BA)
Alternatively, you can verify the SHA512 signature on the files. A unix program called sha or sha512sum is included in many unix distributions.
