Ensuring Package Integrity: GitLab's Omnibus Package Signing Key Update
To maintain the security of Omnibus packages created within CI pipelines, we employ the GNU Privacy Guard (GPG) key for digital signatures, assuring users that the packages remain untampered. This key serves a distinct purpose from other repository metadata signing keys and GPG signing keys for GitLab Runner.
Originally set to expire on July 1, 2023, we're extending the expiration date of the Omnibus package signing key to July 1, 2024.
Why the Extension?
The annual extension of the Omnibus package signing key's expiration aligns with GitLab's stringent security policies. This practice also minimizes potential risks in case the key is compromised. Gitlab opts for key expiration extension over key rotation to ensure a smoother experience for users who validate package integrity checks before installation.
Your Role in the Update
If you're one of the users who validate package signatures on the Omnibus packages distributed by GitLab, you'll need to take some action. Updating your copy of the package signing key is crucial to continue enjoying secure software installations.
It's important to note that the Omnibus package signing key is distinct from the key used by OS package managers like apt or yum to sign repository metadata. If you don't specifically verify package signatures or configure your package manager to do so, no action is required on your end to continue installing Omnibus packages smoothly.
By extending the Omnibus package signing key's expiration, Gitlab is ensuring that your software experience remains secure and uninterrupted.
