Verify a document
Drop a PDF from the Casablanca Stock Exchange or the AMMC. Your browser computes its SHA-256 fingerprint; only the fingerprint is sent, never the document. We tell you whether it is an official document we have archived, when it was first seen, whether its address later served different content, and whether it is in a notarised root.
Privacy: the file never leaves your device.
