Digital Signatures for PDF Documents

Our Digital Signatures eBook is available as a free download from the linked page. Although it was originally written for iText 5/iTextSharp, many of the described concepts and operations are still relevant and transferable to iText 7.

NOTE: The iText 5-based code snippets included in the eBook were accompanied by complete examples available on our website. Since then, they have been completely updated and rewritten for iText 7. This meant significant changes in some cases, and some examples were no longer applicable.
