GrapeCity 博客 - PDF 數位簽章文件

GrapeCity Documents for PDF (GcPdf) is a cross-platform feature-rich PDF API Library for .NET. It helps you generate documents with speed, memory efficiency, and no dependencies.

In this blog post, GrapeCity's Shilpa Sharma takes you through the process of using GcPdf to implement electronic signatures programmatically using .NET C#. This process includes:

• Adding e-Signature (Basic) to PDF
• Add Advanced Electronic Signatures (AdES)
• Add PDF Advanced Digital Signatures (PAdES)
• Add Qualified Electronic Signatures (QES)

Digital Signatures are a vital part of the document management process, as they are used in legal contracts, purchase orders, financial transactions, commercial lease agreements, employee contracts, and much more.
