Upload an IVI eCoC XML file prepared by the manufacturer.

2

Validate

Run automated XML and IVI checks before submission.

3

Sign

Sign the XML using your own signing certificate.

Electronic Certificate of Conformity (eCoC) workflows

In this workflow, electronic Certificates of Conformity are handled as structured IVI XML messages. Preparing the XML is only the first step: manufacturers must also check it, sign it and use the appropriate submission channel.

SignECOC brings IVI XML validation, electronic signing and submission preparation together for manufacturers, homologation departments, compliance teams and software providers.

IVI XML validation and eCoC signing

Check your IVI XML before signing and submission. Sign with a manufacturer-controlled certificate using the Local Signer app or a temporary encrypted session with your PFX/P12 file.

The signing workflow supports XMLDSig and XAdES. Certificate suitability depends on the selected channel and its requirements. With local signing, private keys stay on the manufacturer’s device.
