CREDA-Stamp

Legal document integrity

Prove a document hasn’t changed.

CREDA-Stamp creates a deterministic integrity record at the moment a document is finalized, allowing it to be independently verified later without relying on memory or storage systems.

Create CREDA-Stamp Record

Generate a verifiable integrity record for a finalized document. The same file will always produce the same result.

Why this matters

In legal matters, disputes can arise when multiple versions of a document exist. CREDA-Stamp allows you to prove whether a file matches the original recorded version.
