PDF Xpansion SDK News at a Glance

Support of the ZUGFeRD 2.1.1 specification

At the beginning of July, the Forum elektronische Rechnung Deutschland published ZUGFeRD Specification 2.1.1. This specification is now also supported by PDF Xpansion SDK 14. The specification and with it the SDK now additionally offer a sixth profile: XRechnung. This means that it is now possible to save an XML file created in XRechnung format into PDF/A3 documents and export it from them. With this profile, ZUGFeRD now also directly meets the specific requirements and national (legal) regulations of public administration in Germany. The specifications of the European standard EN16931 are, of course, also fulfilled by ZUGFeRD 2.1.1 without any changes through the corresponding profiles already available.

ZUGFeRD 2.1 Support

From SDK version 14.2.3 PDF Xpansion SDK supports ZUGFeRD 2.1 specification. Thus the SDK serves the use of ZUGFeRD 1, 2 & 2.1 as well as XRechnung and Factur-X.

The invoice formats contribute to increase the acceptance of electronic invoices and to define a general standard in Europe. The technical specifications are based on the international UN/CEFACT standard “Cross Industry Invoice (CII)” and the ISO standard PDF/A-3. They conform to the European standard EN 16931, which defines the standards and technical rules for electronic invoicing in Europe to ensure interoperability and compliance with legal regulations.

Extension of Digital Signatures

The new version of PDF Xpansion SDK 14 offers additional features for the implementation (validation and signing process) of digital signatures in PDF files: The SDK now supports the PAdES signature standard (PDF Advanced Electronic Signatures) according to ISO 32000-2 and to ETSI TS 103 172. PAdES signatures are available as levels B (Basic), T (Time), LT (Long-Term-Validation) and LTA (Long-Term Availability and Integrity of Validation).

Time Stamps in Signatures

Time stamps, according to ISO 32000-2, and to the protocol RFC 3161, can be embedded in all PDF files you generate in your application.
