XAdES – XML Advanced Electronic Signature

Set of advanced electronic signatures based on XML formats. Unlike an embedded system such as PDF-Signature, it’s designed to “discuss among machines”; that is, the XML format is designed for the exchange of information between automated systems. Within this signature format different extensions have evolved meeting different needs and scenarios; the extensions described below aren’t classified by degree of robustness, reliability or security, but should be considered as evolutions of the format that respond to different scenarios and therefore do not compete with each other.
