Certify the existence of your files over time. Built for creatives.
WorkProofVault is for creators, studios, and teams that need to show when a file already existed, with an orderly and verifiable trail.
One workspace for fingerprint, attestation, and future verification.
File existence, integrity, hash matching, and technical prior evidence.
For work that happens before publication, delivery, or signature
When a file arrives already paired with clear technical proof of existence, integrity, and prior availability, people usually handle it with more care. It is a simple way to make delivery feel more serious and more orderly for clients, collectors, galleries, or collaborators.
Ideal for building certified archives for artists.
It helps reinforce the uniqueness of an artwork over time: the certificate, together with a photo of the work, can be delivered to the collector and the gallery as part of the artwork dossier.
You upload the exact file you are actually about to share and lock its context.
The system calculates SHA-256, generates the proof, and prepares the certificate.
You keep the right set for future checks: file, PDF, and `.ots` proof.
The important part starts after you click certify.
For serious verification over time, you need to keep the original file, the PDF certificate, and the `.ots` proof together. The rest of the page can look elegant, but this is the real operational point.
