|
## What is it?
|
|
|
|
This is a reborn tool, used during the epoche dinosaurs were traipsing the earth.
|
|
Basically it analyses PDF files for Metadata. You can direct it to a file or directory with pdfs.
|
|
You can show it the url of a pdf or use the integrated googlesearch (thanx to mario vilas) class
|
|
to search for pdfs at target site, download and analyse them
|
|
|
|
## What information can be gathered?
|
|
|
|
This depends on the software used to create the pdf. And if it has been cleaned.
|
|
However, common are the following things:
|
|
|
|
* Producer
|
|
* Creator
|
|
* CreationDate
|
|
* ModificationDate
|
|
* Author
|
|
* Title
|
|
* Subject
|
|
|
|
and some more :)
|
|
|
|
## How does it work?
|
|
|
|
Every more complex filetype above .txt or alike uses metadata for convinience, customer support or only to spread it has been used.
|
|
There is a lot information about metadata in different sort of files like pictures, documents, videos, music online. This tool
|
|
focuses on pdf only.
