        document.Pages.Add(page)
        
        'Create a Certificate using the system default store
        certificate As Certificate = New Certificate("CertificateSubject")
        
        ' Sign the document - Invisible
        document.Sign("NewFieldName", certificate)
        
        ' Save the document
    document.Draw("C:\MySignedDocument.pdf")
    End Sub
End Module

using System;
using ceTe.DynamicPDF;
          
class MyClass
{
    static void Main(string[] args)
    {
        // Create a PDF Document
        Document document = new Document();
          
        // Create a PDF Page
        Page page = new Page();
          
        // Add the page to the document
        document.Pages.Add(page);
          
        // Create a Certificate using the system default store
        Certificate certificate = new Certificate("CertificateSubject");
                 
        // Sign the document - Invisible
        document.Sign("NewFieldName", certificate);
          
        // Save the document
        document.Draw(@"C:\MySignedDocument.pdf");        
    }
}

Remarks

NOTE: This method requires the .NET Framework 2.0 or greater.

To sign with visible signature, give the Signature field name which is already added into any of the document pages. To sign with invisible, use a different name which does not assign for any of the page elements added into this document pages. Giving existing field name of other page elements apart from Signature will make the document unsigned. This method is not available for .NET standard.

Digitally sign this document with Time stamping.

public void Sign(string fieldName, Certificate certificate, bool timeStamp)

Sub Sign(fieldName As String, certificate As Certificate, timeStamp As Boolean)
