5. Electronic Signature
VaultSign offers simple electronic signatures (Art. 4, Law 14.063/2020) and qualified signatures with an ICP-Brasil digital certificate (e-CPF / e-CNPJ) presented by the signer. It does not offer advanced signatures via Gov.br. The platform does not issue ICP-Brasil certificates: it uses the certificate already issued by a Certification Authority and installed on the signer's device. We record IP, date/time, geolocation, SHA-256 hash, and an audit trail. The validity of a simple signature depends on the parties' consent; the validity of an ICP-Brasil signature follows Provisional Measure 2.200-2/2001 and Law 14.063/2020.
