Examples

The following example will set AES 256 bit security for the document

Imports System
Imports ceTe.DynamicPDF
Imports ceTe.DynamicPDF.PageElements
Imports ceTe.DynamicPDF.Cryptography

Module MyModule
		
    Sub Main()

        ' Create a PDF Document
        Dim MyDocument As Document = New Document 

        ' Create a Page and add it to the document
        Dim MyPage As Page = New Page
        MyDocument.Pages.Add(MyPage)

        ' Create a AES 256 bit security object
        Dim security As Aes256Security = New Aes256Security("owner", "user")

        ' Add the security object to the document
        MyDocument.Security = security

        ' Create and display a label as a reference
        Dim text As String = "This document has been encrypted with AES 256 bit encryption."
        MyPage.Elements.Add(New Label(text, 50, 50, 400, 100, Font.Helvetica, 18))

        ' Save the PDF
        MyDocument.Draw("C:\MyDocument.pdf")

    End Sub
End Module
using System;
using ceTe.DynamicPDF;
using ceTe.DynamicPDF.PageElements;
using ceTe.DynamicPDF.Cryptography;

class MyClass
{
    static void Main()
    {
        // Create a PDF Document
        Document document = new Document();

        // Create a Page and add it to the document
        Page page = new Page();
        document.Pages.Add( page );

        // Create a AES 256 bit security object
        Aes256Security security = new Aes256Security( "owner", "user" );

        // Add the security object to the document
        document.Security = security;

        // Create and display a label as a reference
        string text = "This document has been encrypted with AES 256 bit encryption.";
        page.Elements.Add( new Label( text, 50, 50, 400, 100, Font.Helvetica, 18 ) );

        // Save the PDF
        document.Draw( @"C:\MyDocument.pdf" );
    }
}

Remarks

AES 256 bit PDF security is compatible with PDF version 1.5 and higher and can be read with Adobe Acrobat Reader version X or higher. Older readers will not be able to read document encrypted with this security. Setting document version to lower values will throw an exception at the time of draw. For more details on AES 256 bit security take a look at the Security topic.
