## বৰ্ণনা

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.

 * **Stamp with one click** — “Stamp with Sigelith” next to each file in the Media
   Library, as a bulk action, or in the attachment details. Optionally, every new
   upload in the background.
 * **A badge under the file** — under File blocks (and, if you want, Image blocks),
   on attachment pages, or anywhere with `[sigelith_stamp id="123"]`. The badge 
   is plain HTML with one small stylesheet served from your own site: no script,
   no tracking, no request to Sigelith while your page is viewed. It cannot break
   your theme and your theme cannot break it.
 * **Honest by design** — the badge disappears when the file is replaced, until 
   the new version is stamped. It says what a timestamp proves: that the file existed
   no later than a given time. It does not claim who made the file or that its content
   is true.
 * **Gets stronger with time** — once a week Sigelith seals all its entries, signs
   the seal and anchors it in Bitcoin. The plugin checks this once a day and adds“
   Weekly seal” and “Bitcoin: block” to the badge.

Free, no account, no API key.

How the log and the proofs work, precisely enough to check them yourself: [sigelith.org/spec](https://sigelith.org/spec/).

### External services

This plugin connects to the Sigelith service at https://sigelith.org to record and
check timestamps. It sends nothing until you stamp a file.

 * **When you stamp a file** (by clicking “Stamp with Sigelith”, by the bulk action,
   or — only if you switched it on — automatically after an upload), the plugin 
   sends the file’s SHA-256 fingerprint (64 hexadecimal characters) to `https://
   sigelith.org/api/proof/stamp`. The file itself, its name and the address of your
   site are never sent.
 * **Once a day**, for stamped files whose weekly seal or Bitcoin anchor is not 
   yet complete, the plugin sends the same fingerprint to `https://sigelith.org/
   api/proof/verify` to read their status.
 * **Visitors** of your site never contact Sigelith unless they click “Verify independently”
   on a badge, which opens the public verification page.

Fingerprints in the Sigelith log are public and permanent: an entry cannot be withdrawn.
Nobody can read a file from its fingerprint, but the fact that a file with that 
fingerprint existed becomes public.

## সঘনাই উত্থাপিত প্ৰশ্ন

### 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.
