Do not download from www.apache.org. Please use a mirror site to help us save apache.org bandwidth. Go here to find your nearest mirror.


Many of the files have been digitally signed using GnuPG. If so, there will be an accompanying file.asc signature file in the same directory as the file (binaries/ or source/). The signing keys can be found in the distribution directory at <http://www.apache.org/dist/commons/KEYS>.

Always download the KEYS file directly from the Apache site, never from a mirror site.

Always test available signatures, e.g.,
$ pgpk -a KEYS
$ pgpv commons-collections4-4.1-bin.tar.gz.asc
$ pgp -ka KEYS
$ pgp commons-collections4-4.1-bin.tar.gz.asc
$ gpg --import KEYS
$ gpg --verify commons-collections4-4.1-bin.tar.gz.asc
