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/). A court-appointed expert can follow the step-by-step check in [section 11](https://sigelith.org/spec/#expert). ### 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.

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. ## 常見問題集 ### 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. ## 使用者評論 這個外掛目前沒有任何使用者評論。 ## 參與者及開發者 以下人員參與了開源軟體〈Sigelith Timestamp〉的開發相關工作。 參與者 * [ sigelith ](https://profiles.wordpress.org/sigelith/) [將〈Sigelith Timestamp〉外掛本地化為台灣繁體中文版](https://translate.wordpress.org/projects/wp-plugins/sigelith-timestamp) ### 對開發相關資訊感興趣？ 任何人均可[瀏覽程式碼](https://plugins.trac.wordpress.org/browser/sigelith-timestamp/)、 查看 [SVN 存放庫](https://plugins.svn.wordpress.org/sigelith-timestamp/)，或透過 [RSS](https://plugins.trac.wordpress.org/log/sigelith-timestamp/?limit=100&mode=stop_on_copy&format=rss) 訂閱[開發記錄](https://plugins.trac.wordpress.org/log/sigelith-timestamp/)。 ## 變更記錄 #### 1.0.0 * First release. ## 中繼資料 * 版本 **1.0.0** * 最後更新 **2 天前** * 啟用安裝數 **少於 10 次** * WordPress 版本需求 ** 6.0 或更新版本 ** * 已測試相容的 WordPress 版本 **7.1.3** * PHP 版本需求 ** 7.4 或更新版本 ** * 語言 * [English (US)](https://wordpress.org/plugins/sigelith-timestamp/) * 標籤: * [badge](https://tw.wordpress.org/plugins/tags/badge/)[integrity](https://tw.wordpress.org/plugins/tags/integrity/) [media library](https://tw.wordpress.org/plugins/tags/media-library/)[proof of existence](https://tw.wordpress.org/plugins/tags/proof-of-existence/) [timestamp](https://tw.wordpress.org/plugins/tags/timestamp/) * [進階檢視](https://tw.wordpress.org/plugins/sigelith-timestamp/advanced/) ## 評分 這個項目尚無任何評論記錄。 [撰寫評分](https://wordpress.org/support/plugin/sigelith-timestamp/reviews/#new-post) [查看全部使用者評論](https://wordpress.org/support/plugin/sigelith-timestamp/reviews/) ## 參與者 * [ sigelith ](https://profiles.wordpress.org/sigelith/) ## 技術支援 使用者可在技術支援論壇提出意見反應或使用問題。 [檢視技術支援論壇](https://wordpress.org/support/plugin/sigelith-timestamp/)
