sealbot

sealbot {seal|verify|issue|anchor|watch} [options] [file]

sealbot is the command-line client for Let's Seal, an open standard (SEAL — Sealed Evidence Anchored to a Ledger) for proving that a file is unaltered, sealed by a known certificate, and existed by a certain date. Seals use format-native mechanisms where possible (PAdES for PDF, C2PA for media, detached CMS for arbitrary files) and can be verified without trusting a single vendor forever.Install with `npm i -g sealbot` or run `npx sealbot`. A self-contained Rust build lives in the upstream `cli-rs/` directory. Hosted sealing uses organization API keys; verification is free and works offline once roots and proofs are available.

seal file

Seal a PDF or other file through the Let's Seal API or self-hosted service

Verify a seal offline (integrity, issuer, time anchor)

Issue-related sealing operations (see `sealbot --help`)

Anchor related proofs (e.g. time anchoring workflows)

Watch/automation mode for sealing workflows

Sealing through the hosted service requires network access and credentials. Verification needs pinned trust roots for full authenticity verdicts. Format support varies (PDF, images, XML, email, detached signatures).

Part of the Let's Seal open-source project (Apache-2.0), modeled after free public certificate infrastructure for document authenticity.
