Technically, Autofirma 1.7.2 operates as a local signature provider. When a citizen attempts to sign a form on a government portal (e.g., the Tax Agency or Social Security), the web page calls upon Autofirma installed on the user’s computer. The software then detects available digital certificates, prompts the user for their password, applies the cryptographic signature to the document’s hash (a unique digital fingerprint), and returns the signed document to the browser. One of the key improvements in version 1.7.2 is its handling of multiple signature formats, including CAdES (CMS Advanced Electronic Signatures) and XAdES (XML Advanced Electronic Signatures), both of which are legally binding in Spain. Moreover, this version enhances logging capabilities, allowing administrators to troubleshoot signature failures more effectively—a small but vital feature for IT support teams in public bodies.
