Verify the signatures using the following commands, depending on your use of PGP or GPG:
$ pgpk -a KEYS
$ pgpv apache-activemq-<version>-bin.tar.gz.asc
$ pgp -ka KEYS
$ pgp apache-activemq-<version>-bin.tar.gz.asc
$ gpg --import KEYS
$ gpg --verify apache-activemq-<version>-bin.tar.gz.asc
(Where <version> is replaced with the actual version, e.g., 5.1.0, 5.2.0, etc.).
