zarf component verify

Verifies a published Zarf component signature

Synopsis

Verifies the Sigstore signature stored as an OCI referrer of a published Zarf component manifest.

zarf component verify COMPONENT_SOURCE [flags]

Examples

# Verify a published component with a public key
$ zarf component verify ghcr.io/my-org/my-component:1.0 --key ./public-key.pem


# Verify a keyless signature by its certificate identity
$ zarf component verify ghcr.io/my-org/my-component:1.0 --certificate-identity signer@example.com --certificate-oidc-issuer https://token.actions.githubusercontent.com

Options

      --certificate-identity string             Required identity claim in the signing certificate (keyless verify). Example: signer@example.com or https://github.com/org/repo/.github/workflows/release.yml@refs/heads/main
      --certificate-identity-regexp string      Regex variant of --certificate-identity
      --certificate-oidc-issuer string          Required OIDC issuer claim in the signing certificate (keyless verify). Example: https://github.com/login/oauth or https://token.actions.githubusercontent.com
      --certificate-oidc-issuer-regexp string   Regex variant of --certificate-oidc-issuer
  -h, --help                                    help for verify
      --insecure-ignore-tlog                    Skip Rekor transparency log inclusion verification. Default true for air-gap. Auto-disabled when keyless identity flags are set (keyless signatures require Rekor inclusion proof to remain verifiable past certificate expiry). (default true)
  -k, --key string                              Public key for signature verification
      --trusted-root string                     Path to a Sigstore TrustedRoot JSON. Falls back to the binary-embedded copy when omitted.
      --use-signed-timestamps                   Verify RFC3161 signed timestamps in the bundle. Auto-enabled when the bundle contains TSA timestamp data. Use when signing was done with --tsa-server-url and Rekor was not used.

Options inherited from parent commands

  -a, --architecture string        Architecture for OCI images and Zarf packages
      --cache string               Specify the location of the Zarf cache directory (default "~/.zarf-cache")
      --features stringToString    Provide a comma-separated list of feature names to bools to enable or disable. Ex. --features "foo=true,bar=false,baz=true" (default [])
      --insecure-skip-tls-verify   Skip checking server's certificate for validity. This flag should only be used if you have a specific reason and accept the reduced security posture.
      --log-format string          Select a logging format. Defaults to 'console'. Valid options are: 'console', 'json', 'dev'. (default "console")
  -l, --log-level string           Log level when running Zarf. Valid options are: warn, info, debug, trace (default "info")
      --no-color                   Disable terminal color codes in logging and stdout prints.
      --plain-http                 Allow OCI registry connections over HTTP instead of HTTPS. This flag should only be used if you have a specific reason and accept the reduced security posture.
      --tmpdir string              Specify the temporary directory to use for intermediate files
