I have a problem when I try to set a password for generated document.
If I set the password on an existing document, everything is OK; but when I create and empty document, and the add pages from existing ones, the call to Encrypt does not set any protection.
I’ve reproduced a very small example which clearly shows the problem. In short,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Aspose.Pdf;
using AsposeWrapper;
namespace PasswordProtect
{
class Program
{
static void Main(string[] args)
{
//(new License()).SetLicense("...");
// this way password is set
OpenAndSave();
// this way password is NOT set
AppendAndSave();
}
private static void OpenAndSave()
{
var pdf = new Document(@"path\to\file.pdf");
pdf.Encrypt("password", "", Permissions.PrintDocument |
Permissions.PrintingQuality, CryptoAlgorithm.RC4x128);
pdf.Save(@".\edited.pdf");
pdf.Dispose();
}
// Open a new file, append pages from an existing file, and
// set user password for the new file
private static void AppendAndSave()
{
var pdfFrom = new Document(@"path\to\file.pdf");
var pdfTo = new Document();
pdfTo.Pages.Add(pdfFrom.Pages) ;
pdfTo.Encrypt("password", "", Permissions.PrintDocument |
Permissions.PrintingQuality, CryptoAlgorithm.RC4x128);
pdfTo.Save(@".\edited2.pdf");
pdfFrom.Dispose();
pdfTo.Dispose();
}
}
}
The initial file itself is not encrypted.
This simple code gives the same result with any 7.x Aspose.pdf.dll.
Am I missing something? or is this a bug?
TIA
