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.   To use PDF-AS as a java library checkout the API documentation located at: https://joinup.ec.europa.eu/site/pdf-as/releases/ VERSION /docs/api, or the full javadoc documentation at: https://joinup.ec.europa.eu/site/pdf-as/releases/ VERSION /docs/full.   To use PDF-AS as an external service checkout the documentation located at: https://joinup.ec.europa.eu/site/pdf-as/releases/ VERSION /docs   We provide a maven repository here: https://joinup.ec.europa.eu/site/pdf-as/maven/   Acutal releases and documentation ca be found here: https://joinup.ec.europa.eu/site/pdf-as/releases/   The source code is available here: http://git.egiz.gv.at/pdf-as-4/  

Changes since the 4.0.11

PDF-AS Library

• a new pdf backend is available based on pdfbox 2.0.3, changes that are available with the new backend:
  • unicode characters can now be rendered in the signature block when using TTF fonts
  • when using TTF fonts the new backend includes only a subset of used characters in the resulting document, which reduces the resulting size of the document
• some minor bugs fixes

PDF-AS Web

• some minor bugs fixes
