Verify the chart

cosign verify ghcr.io/quenchworks/charts/mailpit:0.0.12 \

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
