Welcome to the PAdES FAQ web site. This site includes answers to questions already asked about PAdES and lets you ask new questions which we will attempt to answer as soon as possible.

PAdES (acronym of PDF Advanced Electronic Signatures) is a set of standards published by ETSI (TS 102 778 parts 1 to 5) to support European requirements for electronic signatures. PAdES is based on existing PDF Signatures as specified in ISO 32 000. It includes features to support validation of signatures which are stored for years or even decades.

The site is aimed at implementers of PAdES as well as those considering whether PAdES is appropriate to their needs.
