It is essential that you verify the integrity of the downloaded files
using the PGP or SHA512 signatures. Please read
https://httpd.apache.org/dev/verification.html[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
https://www.apache.org/dist/logging/KEYS[KEYS] as well as the asc
signature file for the relevant distribution. Make sure you get these
files from the https://www.apache.org/dist/logging/[main distribution
directory], rather than from a mirror. Then verify the signatures using

[source,sh,subs=attributes]
----
gpg --import KEYS
gpg --verify apache-chainsaw-{ChainsawReleaseVersion}-bin.tar.gz.asc apache-chainsaw-{ChainsawReleaseVersion}-bin.tar.gz
gpg --verify apache-chainsaw-{ChainsawReleaseVersion}-bin.zip.asc apache-chainsaw-{ChainsawReleaseVersion}-bin.zip
gpg --verify apache-chainsaw-{ChainsawReleaseVersion}-src.tar.gz.asc apache-chainsaw-{ChainsawReleaseVersion}-src.tar.gz
gpg --verify apache-chainsaw-{ChainsawReleaseVersion}-src.zip.asc apache-chainsaw-{ChainsawReleaseVersion}-src.zip

Apache Chainsaw {ChainsawReleaseVersion} is signed by {ChainsawReleaseManager} ({ChainsawReleaseKey}).

Alternatively, you can verify the SHA512 signature on the files. A unix
program called sha512sum is included in many unix distributions.
