C E R T E L OProof of Existence

Certificate care

Store your Certificate safely

Keep the Certificate with the unchanged original document so you can verify the proof later. This guide shows one simple structure for both files and an independent backup.

The essential pair

Keep these two files together

Future verification compares your unchanged original document with its Certelo Certificate.

Original document

Your_Original_Document.pdf

Keep the exact file that you certified. Do not edit or convert it.

Certelo Certificate

CERTELO-POE-2026-000847.pdf

Keep the downloaded PDF that records the matching fingerprint.

Keep both in one folder. A Certificate without the unchanged original document cannot complete file verification.
