Works with PDF, images, text files and more. Any file can be protected.
Built on standards that regulators, auditors, and courts recognize
Technology patent filed at the Israel Patent Office. Novel verification architecture.

Legal immunity that even Vertifile can't break. Every layer protects your organization.
Every document gets a unique digital fingerprint. Change one pixel and the fingerprint is completely different.
Two-key verification system. One key signs, another verifies. Impossible to forge the signature.
Document proof is anchored to a public blockchain. Cannot be altered or deleted by anyone, ever.
Zero-knowledge architecture means we never see your content. Not a policy. A mathematical guarantee.

Vertifile is Zero-Knowledge — we cannot read your documents even if we wanted to. Even if forced to.
Your documents are encrypted with AES-256-GCM directly in the browser, before they ever leave your computer. What reaches our servers is unreadable code.
The encryption key is transmitted only via URL Fragment — a part of the address that is never sent to the server. No one besides you and the recipient can open the document.
Every document is signed with a dual digital signature: Ed25519 for sender identity and HMAC for content integrity. Any change, no matter how small, is detected instantly.
Compliant with GDPR, HIPAA and international privacy standards. When the server cannot read — there is nothing to leak, nothing to breach, nothing to expose.
