Hi guys,
I'm looking for tool that can be used on a network share to provide a list of all password protected files (PDF, Excel, Word, Zip) etc. The files are password protected and not encrypted.
I have seen some commercial versions but I wanted to check if anyone knew of any open source version, or how these commercial version recognise that the files have a password associated with them.

In the binary contents of some of these files is a bit or setting of some kind that identifies whether the document is password protected or not. Most of these formats have such a setting, and it's relatively easy to check for, assuming that the file has the appropriate file signature and extension.
