Process

How it works

Verification runs entirely in your browser via the Web Crypto API. Your data never leaves your machine.

Drop or select an .isof file. It is read locally by the browser, with no network request.

The signature level (1 or 2) is detected and the signing block is extracted from the JSON to reconstruct the payload.

For level 2, the X.509 chain is verified up to the hard-coded IsoFind Root CA. The ECDSA P-256 signature is validated against the canonical payload.

The result displays the status, file metadata, signing certificate details and any warnings.

IsoFind PKI

The ISOF format defines two levels of cryptographic protection, graduated according to traceability and authenticity requirements.

SHA-256 hash verification. Guarantees that the content has not been altered since signing.

Level 1

ECDSA P-256 signature with X.509 certificate chain anchored on the IsoFind Root CA.

Level 2

IsoFind PKI chain of trust
