Every FINIS document carries a cryptographic seal — a fingerprint that changes if a single byte does.
Start free → See all capabilitiesThe authenticity seal is a cryptographic fingerprint taken when a document enters FINIS. If the document is altered in any way, the fingerprint no longer matches.
Sending a document securely is only half the problem. The other half is proving, later, that the copy in front of you is the one that was sent.
Automatically, for every document.
Recipients can see the document is sealed.
The seal can be verified independently.
Any change breaks the match.
Show the executed copy is unchanged.
Establish integrity of a document in a dispute.

Anyone holding the document — they do not need a FINIS account.
No. Verification confirms integrity without revealing the document.
Capabilities and guides that work alongside this one.
Verification confirms a document against its seal — and tells you plainly whether it matches.
The recipient reads and signs in the same place — and a decline is recorded just as carefully as a signature.
Every open, every recipient, every timestamp — in one history you can show to someone else.
Not 'access revoked'. The file is erased, and the destruction is on the record.
