OpenPGP Public Keys

Release files for supported releases are signed by the following:

• Jeff Allen (2.7.2 onwards) (key id: 875C3EF9DC4638E3)
• Frank Wierzbicki (2.7.1 and earlier) (key id: 3979A71621665974)

You can validate these keys, using the installer as an example:

gpg --keyserver hkps://keyserver.ubuntu.com --recv-keys [key id]

gpg --verify jython-installer-[x.y.z].jar.asc \
    jython-installer-[x.y.z].jar

GPG will report Good signature from [release owner].

GPG may also report a warning unless you explicitly tell it to trust the key. This is not necessary for one-off verification. The warning is explained here. The signing keys are listed above to allow validation independent of the file repository.
