Digital certificates

A handwritten signature was previously used to validate paper documents. Now you can also sign electronic documents using a digital certificate.

A digital certificate is an identification mechanism that allows you to sign electronically in a quick, simple and secure way from your computer or mobile device. It also makes it easier to complete paperwork and formalities online with full legal guarantees with both public administrations and private entities.

Different digital certificates are available depending on the issuing public body or certification authority.
