Metadata gets cleared after encryption

Aspose.PDF Product Family

Hi all,

I have observed that all document metadata gets cleared after encrypting the document. This includes custom properties. Is this the expected behavior? Is there a way to preserve custom properties?

My code fragment:

PdfFileInfo info = new PdfFileInfo("input.pdf");
...
info.saveNewInfo("temp.pdf");
...
PdfFileSecurity fileSecurity = new PdfFileSecurity("temp.pdf", "output.pdf");
fileSecurity.encryptFile(null, "mypassword", permission, true);

Thanks!

Hi Jennefer,

I have tried to reproduce this issue at my end and couldn't do so. Can you please share the complete code snippet and the PDF you're working with so I could reproduce the problem at my end and resolve the issue?

We're sorry for the inconvenience.

Regards,

Hi shahzad,

Thanks for the quick response.

Find below the complete code. Also attached are the resulting PDF files. The program first saves the metadata into an intermediate pdf file (abc50186.pdf), and finally, encryption is applied (example1-out.pdf). Note that abc50186.pdf contains the meta info but got cleared in example1-out.pdf.

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import com.aspose.pdf.kit.License;
import com.aspose.pdf.kit.PdfFileInfo;
import com.aspose.pdf.kit.PdfFileSecurity;
import com.aspose.pdf.kit.PdfPrivilege;

public class MetaInfoTest {

public static void main(String[] args) {
try {
setLicense();
String inputFile = "C:\\data\\workspace\\Aspose\\example1.pdf";
String outputFile = "C:\\data\\workspace\\Aspose\\example1-out.pdf";
PdfFileInfo info = new PdfFileInfo(inputFile);
File tempFile = File.createTempFile("abc", ".pdf", new File("C:\\data\\workspace\\Aspose"));
OutputStream ostemp = null;
boolean ok = false;
try {
ostemp = new FileOutputStream(tempFile);
info.setMetaInfo("metainfo1", "123");
info.setMetaInfo("metainfo2", "456");
ok = info.saveNewInfo(ostemp);
} finally {
ostemp.close();
}
if(ok) {
InputStream is = null;
OutputStream os = null;
try {
is = new FileInputStream(tempFile);
os = new FileOutputStream(outputFile);
PdfFileSecurity fileSecurity = new PdfFileSecurity(is, os);
fileSecurity.encryptFile(null, "mypassword", PdfPrivilege.ScreenReaders, true);
} finally {
is.close();
os.close();
}
}
} catch(Exception e) {
e.printStackTrace();
}
System.exit(0);
}

private static void setLicense() throws Exception {
License license = new License();
String licFile = "C:\\data\\workspace\\Aspose\\Aspose.Pdf.Kit.license";
FileInputStream stream = new FileInputStream(licFile);
license.setLicense(stream);
}
}

If the following info helps:
I am using Acrobat 7.0 Standard to open the PDF files
I am using the latest Pdf Kit 2.3.0.0

Thanks!
