详情介绍:

Sigelith Timestamp records that a file existed at a point in time — without sending the file anywhere. When you stamp a file, the plugin computes its SHA-256 fingerprint on your server and records those 64 characters in the public, append-only Sigelith log. Anyone can later check, with standard tools and without trusting you or Sigelith, that a file with exactly these bytes existed no later than the stamped time and has not changed since. Free, no account, no API key. How the log and the proofs work, precisely enough to check them yourself: sigelith.org/spec. A court-appointed expert can follow the step-by-step check in section 11.

安装:

  1. Upload the sigelith-timestamp folder to /wp-content/plugins/, or install the plugin from the Plugins screen.
  2. Activate it.
  3. In Media → Library (list view), choose "Stamp with Sigelith" under a file.
  4. Optional: Settings → Sigelith Timestamp.

  • "Stamp with Sigelith" and the status column in the Media Library.
  • Settings → Sigelith Timestamp.

常见问题:

Does my file leave my server?

No. Only its SHA-256 fingerprint does.

Which file is stamped?

The file behind the attachment's URL — the one your readers download. For large images WordPress serves a scaled copy; that copy is what gets stamped.

What happens if I replace the file?

The badge disappears and the Media Library shows that the file changed. Stamp the new version to get a new badge. Earlier stamps stay in the public log and in the attachment's history.

Is this a qualified electronic timestamp under eIDAS?

No. It is evidence anyone can check, not a qualified trust service, so it carries no legal presumption. See https://sigelith.org/spec/#attest

What if the Sigelith service is unavailable?

Stamping is retried automatically. The service pauses new stamps on purpose when it cannot confirm its clock against the reference time; the plugin waits and tries again.

Does the plugin keep anything when I delete it?

Your settings are deleted. The stamp records stay in your attachments' metadata on purpose: they are your copy of public, permanent proofs.
