 The Tutorials container image is signed using [Sigstore's](https://sigstore.dev/) Cosign. The container image is signed using a cryptographic key pair that is private and stored internally. The public key is available in the official Spectro Cloud documentation repository at [**static/cosign.pub**](https://raw.githubusercontent.com/spectrocloud/librarium/master/static/cosign.pub). Use the public key to verify the authenticity of the container image. You can learn more about the container image signing process by reviewing the [Signing Containers](https://docs.sigstore.dev/signing/signing_with_containers) documentation page.
