Hello everyone,
I am using PDFBox 2.0.4 and I couldn't find the best way to do it.
I hope you can help me :-)
I have a simple application that accepts PDF files (among other formats),
and I currently pass it along (as argument to methods) as a File. In order
to cleanup my code, I wanted to pass it as an InputStream instead... but I
... which is not a good idea as it will make everything slower. Because
PDFBox makes an internal copy to allow random access.
miss one feature in PDFBox 2.0 detecting if the file is password protected.
I think it was possible using the 1.8 version, as we instantiated the doc and
*then* we'd give it the password.
Sample code:
```
try (PDDocument ignore = PDDocument.load(inFile)) {
return null; // not password protected
} catch (InvalidPasswordException ignore) {
}
```
That code has a memory leak as "ignore" isn't closed
The issue is that when I try to reuse inFile, it tells me it has been closed.
I doubt that. Unless "inFile" is an input stream and not a file, as the
name would suggest.
When wrapping it in a CloseShieldInputStream, the whole file is read... leading
to an unwanted memory consumption and/or a temporary file.
This was not an issue with File-s because I could re-recreate an InputStream
when I needed to.

password is the right one, without PDFBox reading it as a whole?
|document.isEncrypted() == true|
then it is encrypted and you gave the correct password (which can be the
empty password!!!).
If it is encrypted and you gave the wrong password then you'll get an
InvalidPasswordException
