The PGP signatures can be verified using PGP or GPG. First download the KEYS 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 verify the signatures using
% pgpk -a KEYS % pgpv poi-X.Y.Z.jar.asc

% gpg --import KEYS % gpg --verify poi-X.Y.Z.jar.asc
