Description
Security API. This dynamic-link library will do its best to ensure security of your documents. It uses the latest achievements in document security encryption (standard 40-bit or 128-bit supported by Acrobat Reader 5.0 and up). PDF Extract API can be used both as a server DLL module (try it now) allowing online PDF files processing and as a parsing engine (download our samples) running on .NET platform with C#, Visual Basic, C++, J# support. PDF Extract API uses exportable C-language style functions.
Features
PDF Security API provides you with 4 effective features:
  • Preventing a document from printing. The Print button will not be active.
  • Preventing a document from editing. No changes to the encrypted document will be allowed.
  • Preventing a document from copying. The PDF document will be able to be opened only in specified directory or on certain sever.
  • Setting a password for opening a document.
  • Setting a password for editing a document.
  • Only a few lines of code are needed to make the first application work, so you can concentrate more on customizing an appearance of your program and defining the most efficient way it may be exploited.
    C# Sample Code

    private void bApply_Click(object sender, EventArgs e)

         {

    if (edSourcePDF.Text.Trim().Length > 0 && edTarget.Text.Trim().Length > 0)

           {

              PDFSXAPI.NPD_LockEdit(edSourcePDF.Text, edTarget.Text);

           }

      else

           {

              MessageBox.Show("Please, specify source and target paths");

           }

         }
