title: "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, dnf 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-gpg-keys package,

and are typically found in the /etc/pki/rpm-gpg directory.

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 dnf 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:

```plain

$ gpg --show-keys /etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
