CentOS GPG Keys

How CentOS uses GPG keys

Each stable RPM package that is published by CentOS Project is signed with a GPG signature. By default, yum and the graphical update tools will verify these signatures and refuse to install any packages that are not signed, or have an incorrect signature. You should always verify the signature of a package prior to installation. These signatures ensure that the packages you install are what was produced by the CentOS Project and have not been altered by any mirror or website providing the packages.

Importing Keys

The Project GPG keys are included in the centos-release package, and are typically found in /etc/pki/rpm-gpg. Please note that not all keys in this directory are used by the CentOS project. Some keys may be placed in this directory by 3rd party repositories to enable the secure use of extra packages as well. The keys used by CentOS are enabled in the yum repository configuration, so you generally don’t need to manually import them.

If you want to verify that the keys installed on your system match the keys listed here, you can use GnuPG to check that the key fingerprint matches. For example:

gpg --quiet --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
        pub  4096R/F4A80EB5 2014-06-23 CentOS-7 Key (CentOS 7 Official Signing Key) <security@centos.org>
          Key fingerprint = 6341 AB27 53D7 8A78 A7C2  7BB1 24C6 A8A7 F4A8 0EB5
