password protected doc and docx file in java

Question

I want to protect doc and docx files with password using java. I have tried using Apache POI. But it can't help me out.I am not getting any file at the location How would I do that? Any another way or API??

            POIFSFileSystem fs = new POIFSFileSystem();
            EncryptionInfo info = new EncryptionInfo(fs);
            File file=new File("D:/abc.doc");
            Encryptor enc = info.getEncryptor();
            enc.confirmPassword("xxxxx");

            OPCPackage opc = OPCPackage.open(file,PackageAccess.READ_WRITE);
            OutputStream os = enc.getDataStream(fs);
            opc.save(os);
            opc.close();

            FileOutputStream fos = new FileOutputStream("D:/abc12345.docs");
            fs.writeFilesystem(fos);
            fos.close();

See: http://www.quicklyjava.com/create-password-protected-excel-using-apache-poi/

Try this constructor for info object:

EncryptionInfo info = new EncryptionInfo(EncryptionMode.agile);

The constructor EncryptionInfo(POIFSFileSystem, EncryptionMode) is undefined – Amar Malik Jun 18 '18 at 10:15
I have added a snapshot for the POI versions – gargkshitiz Jun 18 '18 at 10:38
Why are you recommending such old versions of Apache POI? Those ones are 4 years old! – Gagravarr Jun 18 '18 at 11:07

Please do some googling around it. See https://stackoverflow.com/questions/34924676/how-to-read-doc-file-using-poi for example – gargkshitiz Jun 19 '18 at 07:16
