PDFResurrect is a tool aimed at analyzing PDF documents. The PDF format allows for previous document changes to be retained in a more recent version of the document, thereby creating a running history of changes for the document. This tool attempts to extract all previous versions while also producing a summary of changes between versions.
This tool can also “scrub” or write data over the original instances of PDF objects that have been modified or deleted, in an effort to disguise information from previous versions that might not be intended for anyone else to read.
v0.9 is a bug fix release and addresses the gathering of data (within limit) for the Creator MetaData at the end of a PDF. The previous version would stop prematurely, or possibly get too much info (in certain cases).
