Funtoo Linux stage tarballs are signed using GPG by the build server they are built on. The following keys are used to create detached binary signatures ending in .gpg of each stage tarball:

GPG key name/emailGPG commentGPG Key IDFingerprintGPG Key Type

In turn, these public keys are signed by the Funtoo Linux master signing key:

To verify the integrity of stage3 tarballs using GPG, first download your preferred stage3 taball, and the matching file with the additional .gpg extension in the same directory. Then perform the following steps:

root # gpg --recv-key 11FD00FD
root # gpg --recv-key 683A2F8A
root # gpg --verify stage3-latest.tar.xz.gpg stage3-latest.tar.xz

You should see output similar to this:

gpg: Signature made Sat 10 Dec 2016 08:46:41 PM MST using RSA key ID 4FF347DD
gpg: Good signature from "Daniel Robbins (metro:excavator) <drobbins@funtoo.org>" [ultimate]
