PreuveTierce – Certify document integrity and existence with RFC-3161

Summary: PreuveTierce uses RFC-3161 trusted timestamping to prove document existence and integrity without storing the original files. It processes only SHA-256 hashes within a zero-knowledge architecture, enabling public verification and authenticity certificate generation.

What it does

It timestamps cryptographic hashes of documents using RFC-3161 standards and provides a public portal for verification and certificate issuance without retaining the original documents.

Who it's for

Users needing legal proof of document existence and integrity through verifiable timestamps without exposing document content.

Why it matters

It ensures document authenticity and existence while preserving privacy by never storing the original files.
