Signature and attestation verification

The image and release artifacts are signed keylessly with Sigstore Cosign. The container also has GitHub build provenance attached.

Verify the image signature:

cosign verify ghcr.io/wenisch-tech/smtp2x@sha256:c3ec0fbf65aab276d9bf1f147e2ecfafff949ab55864bb12e3814f890423ce62 \
  --certificate-identity-regexp="https://github.com/wenisch-tech/SMTP2X" \
  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"

Verify the build provenance:

gh attestation verify oci://ghcr.io/wenisch-tech/smtp2x@sha256:c3ec0fbf65aab276d9bf1f147e2ecfafff949ab55864bb12e3814f890423ce62 \
  --repo wenisch-tech/SMTP2X

Verify the Helm chart signature after downloading the chart and its .cosign.bundle from this release:

cosign verify-blob smtp2x-0.1.2.tgz \
  --bundle smtp2x-0.1.2.tgz.cosign.bundle \
  --certificate-identity-regexp="https://github.com/wenisch-tech/SMTP2X" \
  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"

Verify the application JAR in the same way:

cosign verify-blob smtp2x-0.1.2.jar \
  --bundle smtp2x-0.1.2.jar.cosign.bundle \
  --certificate-identity-regexp="https://github.com/wenisch-tech/SMTP2X" \
  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"
