To ensure the integrity of the release artifacts they are digitally signed. You can find more information about the way that we sign releases here. You must verify the integrity of the downloaded files using signatures downloaded from our main distribution directory.

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 our main distribution directory, rather than from a mirror. Then verify the signatures using, for example
pgpk -a KEYS
pgpv apache-tuscany-sca-1.2-incubating.tar.gz.asc
