The .isof file embeds a SHA-256 fingerprint computed at export. Any modification to the content is immediately detectable, without a network connection.
ECDSA P-256 · X.509 certificate
The file is signed with your private key, bound to a certificate issued by the IsoFind Issuing CA. The certificate names a person, or a laboratory and its legal entity. Any third party can verify the signer's identity without a network connection.
Each certificate is signed by the IsoFind Issuing CA and embedded in the .isof file. Verification depends on no external service.
The SHA-256 fingerprint of the canonical JSON representation is covered by the ECDSA signature. Any modification, even a single digit, invalidates the signature.
The X.509 certificate binds an ECDSA P-256 public key to an identity verified by IsoFind before issuance: a person, checked against an identity document, or a laboratory and its legal entity.
The certificate traces back to the IsoFind Root CA (RSA 4096, offline). Both the Root CA and the Issuing CA are embedded in the IsoFind binary.
Full verification (chain, validity, embedded CRL, ECDSA signature) works without a network connection, which matters for air-gapped environments.
IsoFind PKI infrastructure
Top of the trust chain. Signs only the Issuing CA. Private key stored offline on an encrypted physical medium, never connected to any network.
Issues personal and laboratory certificates. Private key on a hardware HSM. Publishes a CRL for revocation. Embedded in the IsoFind binary for offline verification.
Bound to the private key generated locally within IsoFind. The private key never leaves the workstation. The certificate is renewable every year.
A personal certificate certifies your name only. An organization certificate also certifies the entity you sign for, and its tier depends on the legal entity named in the certificate, not on the group it belongs to.

An example. A researcher at a national laboratory who takes a personal certificate signs under her own name only: her files show who signed them, without committing her laboratory. If she signs with her laboratory's organization certificate, the signature also carries the laboratory's name, certified as well, and the laboratory stands behind it.
Each certificate is valid for one year and renews at the same price. It is independent of the software licence: it works with Essential, Research or Pro, and verifying ISOF files remains open to everyone. Net prices, French VAT not applicable under article 293 B of the CGI. By ordering, you accept the terms and conditions of sale.
Four steps. Your private key never leaves your machine: only its public part reaches us, inside your request.
Choose your certificate above and pay by card. For an organization certificate, enter the exact name of the entity and of the laboratory.
In IsoFind, go to Certificates > New certificate. Your private key is created on your machine, encrypted with AES-256-GCM. Send the .csr file to colin.ferrari@isofind.tech, from the address used for your order.
Personal certificate: you receive a link to present an identity document, checked by Stripe. Organization certificate: we check the entity, and may ask you for a supporting document.
You receive a .crt file. Import it via Certificates > Import: your .isof files can then be signed at level 2. If the verification fails, your order is refunded in full.
