How can I blast a multi-page PDF file into several encrypted single-page PDF files?

With the help of VeryPDF PDF Toolbox, you can easily burst a multi-page PDF file into multiple single-page PDF files, each of which is protected by an open password and/or a permissions password with strong encryption length.

Below are some code samples explaining how to blast PDF into password protected PDF in programming languages: ASP.NET, C#, and VB.NET.

C# code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Call_PDFToolBoxCom
{
    class Program
    {
        static void Main(string[] args)
        {
          string strExePath = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
          PDFToolBoxCom.PDFToolBoxCom p = new PDFToolBoxCom.PDFToolBoxCom();
          string strReturn = p.RunCMD(strExePath + @"\in.pdf -split -ownerpassword foopass -permit lowprinting");
          Console.WriteLine(strReturn);
          Console.WriteLine("Please enter any key to continue...");
          Console.ReadKey();
        }
    }
}

VB_NET code:
Module Module1
    Sub Main()
        Dim p As PDFToolBoxCom.PDFToolBoxCom
        Dim strRet As String
        Dim strParam As String
        Dim strPath As String
        strPath = AppDomain.CurrentDomain.SetupInformation.ApplicationBase
strParam = strPath + "pdftoolbox.exe " + strPath + "in.pdf" + " -split -ownerpassword foopass -permit lowprinting"
        Console.WriteLine(strParam)
        p = New PDFToolBoxCom.PDFToolBoxCom()
        strRet = p.RunCMD(strParam)
        Console.WriteLine(strRet)
        Console.WriteLine("Please enter any key to continue...")
        Console.ReadKey()
    End Sub
End Module

ASP_NET code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace ASP_NET_Call_PDFToolBoxCom
{
    public partial class _Default : System.Web.UI.Page
    {
      protected void Page_Load(object sender, EventArgs e)
      {}
      protected void Button1_Click(object sender, EventArgs e)
      {
         Console.WriteLine("UserName: {0}", Environment.UserName);
         PDFToolBoxCom.PDFToolBoxCom p = new PDFToolBoxCom.PDFToolBoxCom();
         string strPath = @"E:\bin\pdftoolbox.exe";
         strPath += @" in.pdf -split -ownerpassword foopass -permit lowprinting";
         string strRet = p.RunCMD(strPath);
         Response.Write(strRet);
      }
   }
}
