Digital sign PDF documents with PHP

Qualified Document Level Timestamp Signature

This demo adds document level timestamp (PDF 2.0) to a PDF document while using service providers offering eIDAS qualified timestamps.

A document level timestamp establishes the exact contents of the complete PDF file at the time indicated by the timestamp. The qualified timestamp signature is created by an external timestamp server, so no signature process is done locally. The communication between the component and the timestamp server conforms to RFC 3161.
