DsPdf protects your documents using basic security properties like EncryptHandler, OwnerPassword, UserPassword, AllowCopyContent, AllowEditContent, AllowPrint, and more. It is also possible to secure the PDF documents by signing them digitally with a timestamp from the Time Stamp Authorities (TSA). See Security.
Digital Signatures: Add image-based visual signatures or digital signatures with X509 certificates for document security and workflow management. DsPdf supports incremental updates for adding multiple signatures to PDFs. See Digital Signature.
Incremental Update: DsPdf supports incremental updates, which, among other things, enable the addition of multiple digital signatures to a PDF document while maintaining their validity. See Incremental Update.
PDF Layers: Add, edit, and remove layers of PDF documents programmatically using C#. DsPdf supports creating layers, associating content (such as a content stream, FormXObject, and annotation) with different layers, and setting their properties. You can selectively view or hide specific content sections. See Layers.
Complex Graphic Layout Support: DsPdf supports drawing graphics, text, and images without having to calculate the positions of each element relative to other ones. See Layouts and Complex Graphic Layouts.
Table Support: Create tables with complex layouts using DsPdf’s layout engine, which handles the calculation part according to your desired layout, style, and content. See Tables.
