Verifying authenticity of Codefresh artifacts

Verify integrity of Codefresh-generated container and forked Argo CD images

Codefresh signs all artifacts it provides using Sigstore. Verify the authenticity of Codefresh artifacts and forked Argo Project images.
Find more information on Sigstore here.

Verify authenticity of Codefresh artifacts

Verify the authenticity of all artifacts that Codefresh provides with this command:

$ cosign verify --certificate-identity-regexp "https://github.com/codefresh-io/oci-sigstore/.*" --certificate-oidc-issuer "https://token.actions.githubusercontent.com" <IMAGE>

where:
<IMAGE> is the name of the container image to verify.

Verify authenticity of forked Argo Project images for GitOps Runtimes

Verify the authenticity of forked Argo Project images for Codefresh GitOps Runtimes with this procedure.

  1. Find the release of the forked Argo Project component you want to verify.
    For example, Argo CD images in https://github.com/codefresh-io/argo-cd/releases.
  2. Install Cosign.

  3. Run:
    cosign verify --certificate-identity-regexp "https://github.com/codefresh-io/.*" --certificate-oidc-issuer "https://token.actions.githubusercontent.com" <REGISTRY>/<COMPONENT>:<TAG>

    where:

    • <REGISTRY> is the registry containing the forked Argo image to verify, for example, quay.io/codefresh.
    • <COMPONENT> is the Argo CD component to verify, for example, argocd.
    • <TAG> is the version of the forked Argo image to verify, for example, v2.8.1-cap-CR-21281-new-reporter.
Example of verification with Cosign
`$ cosign verify --certificate-identity-regexp "https://github.com/codefresh-io/.*" --certificate-oidc-issuer "https://token.actions.githubusercontent.com" quay.io/codefresh/argocd:v2.8.1-cap-CR-21281-new-reporter`  


   `Verification for quay.io/codefresh/argocd:v2.8.1-cap-CR-21281-new-reporter --`
    `The following checks were performed on each of these signatures:`
      `- The cosign claims were validated`
      `- Existence of the claims in the transparency log was verified offline`
      `- The code-signing certificate was verified using trusted certificate authority certificates`

Authenticity of third-party images in Codefresh

To verify the authenticity of third-party images such as NGINX, Bitnami charts for Redis, MongoDB, and Sealed Secrets that Codefresh uses, refer to the official documentation of each component.
