check encrypted PDFs #1456

Open GoogleCodeExporter opened 9 years ago

The iText JAR has currently only one reference.
It checks in the UploadHandler if the PDF is encrypted.

The UploadHandler class is not even in use currently.
FileUploadHandler is the upload servlet for the new File Explorer.

I am not sure if encrypted PDFs are currently workign with FileUploadHandler.

One should check if encrypted PDFs work and/or if we need the iText JAR for 
that check.

There are two strategies for making sure that a PDF is encrypted:
1) run a conversion with ImageMagick / Ghostscript on ALL uploaded PDFs, 
convertingthe PDF into another PDF. ImageMagick/Ghostscript will then create a 
non encrypted one.
2) Check by iText and only convert those that are really encrypted into a 
non-encrypted.

However I am not sure if we did implemente 1 or 2 (cause I don't remember if 
iText correctly detects encrypted PDFs)
