Verifying a Document
The public verification page. Check any sealed Docshark document's authenticity, fingerprint, and protection state.
Anyone holding a sealed Docshark document can verify it. No account, no relationship with the sender required. The verification page is public by design: a seal that needs the sealer's permission to check is not much of a seal.
How to verify
- Go to the verification page. Linked from the certificate in every sealed PDF.
- Upload the sealed PDF (or paste its record fingerprint).
- The page reports the check.
What the report shows
- Authenticity. Whether the document matches a recorded Docshark envelope.
- The record fingerprint. The integrity hash, recomputed and compared against the stored record.
- Signing parties and timeline. Who signed and when, per the audit record.
- Protection state. Whether watermark and screenshot protection were active at signing.
- The support reference. The identifier to quote if you need the underlying record from Docshark.
What a failed check means
A document that fails verification is not what it claims. Altered after sealing, assembled from pieces, or never a Docshark record at all. Treat it as untrusted and, if the stakes matter, contact the sender through a channel you already trust (not the contact details inside the suspect file).
What verification covers: and what it doesn't
- Covers: the sealed PDF's integrity against Docshark's record. "is this the document the envelope produced?"
- Does not cover: the truth of what the document says, the authority of the people who signed it, or whether the underlying agreement is enforceable. Verification proves the record; judgment proves the deal.
