The electronic signature bundle provides an API for interacting with multiple pdf-as and moa-ssp servers and allows singing and signature verification of PDF files using PAdES.

Compared to using PDF-AS/MOA-SPSS directly it adds authentication/authorization and a simplified REST API for the following three flows:

Advanced signature flow: Synchronously sign PDF file using certificates on the pdf-as server
Qualified signature flow: Asynchronously sign a PDF using handy-signatur.at
(work in progress) Signature verification flow: Verify the integrity and trust chain of a PDF using moa-spss

The following diagram shows the systems involved in signature creation and verification for all provided flows:
