gh-attestation-trusted-root - Output trusted_root.jsonl contents, likely for offline verification

gh attestation trusted-root [--tuf-url <url> --tuf-root <file-path>] [--verify-only] [flags]

Output contents for a trusted_root.jsonl file, likely for offline verification.

When using gh attestation verify, if your machine is on the internet, this will happen automatically. But to do offline verification, you need to supply a trusted root file with --custom-trusted-root; this command will help you fetch a trusted_root.jsonl file for that purpose.

You can call this command without any flags to get a trusted root file covering the Sigstore Public Good Instance as well as GitHub's Sigstore instance.

Otherwise you can use --tuf-url to specify the URL of a custom TUF repository mirror, and --tuf-root should be the path to the root.json file that you securely obtained out-of-band.

If you just want to verify the integrity of your local TUF repository, and don't want the contents of a trusted_root.jsonl file, use --verify-only.

Configure host to use
Path to the TUF root.json file on disk
URL to the TUF repository mirror
Don't output trusted_root.jsonl contents
