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-flume-1.3.1-src.tar.gz.asc
