Document Integrity and
Timestamp Anchor

Paste a document, give it an anchor day in yyyymmdd form and a reference token of your own choosing, such as a receipt id, and this tool fingerprints the text and binds that fingerprint to the day and reference you gave it. Paste the digest back in later alongside the same document and it tells you whether the two match. The anchor day is the value you type, this page reads no clock, and the cryptographic strength of the result lives in the SHA-256 execution hash on the exported Policy Mandate, not in the day key itself.
