PDF-AS 4.1.1 Switch to the latest release

Published on: 29/08/2017 Last update: 13/02/2024

PDF-AS is a java framework for creating digitial signatures on PDF documents. PDF-AS is also capable of verifying digitally signed PDF documents.

From version 4.0 onwards PDF-AS supports only PDF Advanced Electronic Signatures (PAdES). As signature creation device a citizen card environment (CCE), a MOA-SS (> 2.0), or a software keystore (PKCS12, Java Key Store) can be used. To perform a full certificate verification during the signature verification process PDF-AS needs a MOA-SP (>2.0).


PDF-AS is able to create visual signature blocks according to the Austrian Amtssignatur Layout (here). 


PDF-AS can be used directly within a Java application as a library, or via Web or Soap Interfaces as an external service.
