Decrypt-problem- pdf corrupt

Aspose.PDF Product Family
1

Hi,

in the zip-file I provide a pdf, that is encrypted. After the decryption, the file seems to be corrupt (the decrypted file is in the zip-file as well). Reading this file with other applications causes a storage violation exception. Reading the file with acrobat reader causes an error as well. Could you please check?
this is the source I use (using Aspose.pdf.dll v. 7.0.0.0):

string sInFile = “Aspose_PDF_corrupt.pdf”;

string sOutFile = “Aspose_PDF_corrupt_new.pdf”;

Aspose.Pdf.License pLic = new Aspose.Pdf.License();

pLic.SetLicense(“Aspose.Total.lic”);



System.IO.MemoryStream ms = new System.IO.MemoryStream();



try

{

Aspose.Pdf.Facades.PdfFileInfo fileInfo = new Aspose.Pdf.Facades.PdfFileInfo(sInFile);

if (fileInfo.IsEncrypted)

{

Aspose.Pdf.Facades.PdfFileSecurity sec = new Aspose.Pdf.Facades.PdfFileSecurity();

sec.InputFile = sInFile;

sec.OutputStream = ms;

bool bOk = sec.DecryptFile("");



System.IO.MemoryStream msx = new System.IO.MemoryStream();

msx.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);



msx.Position = 0;



FileStream fs = File.OpenWrite(sOutFile);

if (msx != null)

{

msx.WriteTo(fs);

fs.Flush();



}

fs.Close();

fs.Dispose();

}

}

catch (Exception ex)

{

MessageBox.Show("Error " + ex.Message);

}

}

kind regards,
Oliver

Hi Oliver,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Please modify your code as below to resolve your corrupt file issue. I checked it with the latest version of Aspose.Pdf for .NET v7.3 and it works fine.

string sInFile = @"D:\Aspose_PDF\Aspose_PDF_corrupt.pdf";

string sOutFile = @"D:\ Aspose_PDF\Aspose_PDF_corrupt_new.pdf";

using (MemoryStream ms = new MemoryStream())

{

try

{

Aspose.Pdf.Facades.PdfFileInfo fileInfo = new Aspose.Pdf.Facades.PdfFileInfo(sInFile);

if (fileInfo.IsEncrypted)

{

Aspose.Pdf.Facades.PdfFileSecurity sec = new Aspose.Pdf.Facades.PdfFileSecurity();

sec.InputFile = sInFile;

sec.OutputStream = ms;

bool bOk = sec.DecryptFile("");

using (MemoryStream msx = new MemoryStream())

{

ms.WriteTo(msx);

using (FileStream fs = File.OpenWrite(sOutFile))

{

msx.WriteTo(fs);

}

}

}

}

catch (Exception ex)

{

}

}

Sorry for the inconvenience,
