Andreas,
Thanks for quick help!
Following are the answer for you asking's
Can you provide me a failing .doc file? That are attached please find the
same(password: 123456).
So reading/writing the .docx files works, right? Yes, am able read the .docx
file but not able to write.
In addition I have added the code which I have written the to read docx and doc
both.
Sample Code:-
FileInputStream fis = new FileInputStream("sample1.doc");
try {
fs = new POIFSFileSystem(fis);
System.out.println("File is password protected");
EncryptionInfo info = new EncryptionInfo(fs); //It will throw
exception(posted below) at this line, but if we pass .docx file to
FileInputStream it will work properly.
Decryptor d = Decryptor.getInstance(info);
if (d.verifyPassword("123456")) {
InputStream dataStream = d.getDataStream(fs);
document = new XWPFDocument(dataStream);
} else {
throw new ApplicationException("Unable to process:
wrong password ");
}
} catch (OfficeXmlFileException e) {
System.out.println("File is Not password protected");
document = new
XWPFDocument(POIXMLDocument.openPackage(srcPath));
}
Exception thrown is:-
java.io.FileNotFoundException: no such entry: "EncryptionInfo"
Thanks and Regards,
Ajeet Singh

Currently the CryptoAPI method is not supported. Maybe your .doc file is using
this encryption method.
Furthermore the XOR obfuscation differs slightly for .xls and .doc files, and I
have only tested/developed it with .xls files :| ... and afaik both RC4/XOR
methods are record based encryption opposed to standard/agile encryption where
the whole file is encrypted in one stream, so POI supports it only for .xls
Can you provide me a failing .doc file?
So reading/writing the .docx files works, right?
