Document Verification
Every document we formally issue is registered with its identifier, version, issue date and SHA-256 fingerprint. This page — and only this page, at espoirfrontier.com — is where those records can be checked.
Verify by document ID
The document ID is printed in the header of every issued document, next to the QR code (for example, EF-CSP-2026-0001).

Drop the PDF you received. Your browser computes its SHA-256 fingerprint and compares it against the registry.

SHA-256 · computed locally
Your file never leaves your device. The fingerprint is computed inside your browser; nothing is uploaded to us or to anyone else.
What a result means
Registered.
The ID or fingerprint matches a formally issued document. Check that the version and issue date match the copy you hold; earlier versions are marked as superseded.
Not in the registry.
The registry lists formally issued documents only. Drafts, internal papers and third-party material do not appear here. If a document presented to you as issued by ESPOIR FRONTIER cannot be verified on this page, treat it as unauthorized and contact us at contact@espoirfrontier.com before acting on it.
One address.
We operate no other verification page, and official correspondence is sent only from @espoirfrontier.com addresses.
