When a document is completed, XOsign creates a cryptographic fingerprint of it and attaches a trusted timestamp. Together these let anyone confirm, later, that the document hasn't been altered since it was signed.
Checking a document
- Go to the verify page.
- Provide the document or its fingerprint.
- XOsign confirms whether it matches what was signed and when it was timestamped.
This works for anyone who receives the document, not just the signers — it's how a third party confirms a signed document is genuine.
