Steps for setting an EncryptionAlgorithm

  1. Import the trial Developer License:


    License.Import(new StreamReader(@"C:\Users\Joe\license.xml"));

  2. Locate the PDF files using OpenFileDialog:


    OpenFileDialog OpFile = new OpenFileDialog();
    //show only PDF Files
    OpFile.Filter = "PDF Files (*.pdf)|*.pdf";

    if (OpFile.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
    ...

  3. Create a new PDFDocument object:


    PdfDocument document = new PdfDocument();

  4. Add the file the user selected to the new PDFDocument:


    document.Path = OpFile.FileName;

  5. Create a new Security Handler object and Assign the Password string values:



    //Note: Inorder to set passwords an Encryption Algorithm must be set
     PdfPasswordSecurityHandler securityHandler = new PdfPasswordSecurityHandler();
     securityHandler.OpenPassword = "user";
     securityHandler.OwnerPassword = "owner";
    ...

  6. Assign an encryption algorithm :


    //Note: In order to set the an encryption algorithm, passwords must be set on the document
    securityHandler.EncryptionAlgorithm = EncryptionAlgorithm.Aes256BitsX;
    ...

  7. Write the changes back into the document.:


    document.SaveProtected(securityHandler, OverwriteMode.ForceOverwrite);
    ...
