Opaf! It's an Open PDF Analysis Framework!

A pdf file rely on a complex file structure constructed from a set tokens, and grammar rules. Also each token being potentially compressed, encrypted or even obfuscated. Open PDF Analysis Framework will understand, decompress, de-obfuscate this basic pdf elements and present the resulting soup as a clean XML tree(done!). From there a set of configurable rules can be used to decide what to keep, what to cut out and ultimately if it is safe to open the resulting pdf projection(50%done!).

INSTALLATION: This is now available a pypi package on http://pypi.python.org/pypi/OPAF/ For install just do a

$easy_install opaf

Update: A windows installation screencast http://bit.ly/feJQf9

It has an embedded pdflib to generate pdfs. It generates python scripts that generates the parsed pdf. Etc..

Its open source! HELP!!

Tasks:

Move the PLY lexer definition to a class (1) (2) (3)
Add test cases for each possible lexing token (1)(2)(4)
Generate the parsers from "python setup install" (5)
Make it possible to register and unregister Filters (6)
Improve and enforce the use of /DecodeParms and its defaults (6)
Test the PNG Predictors decoders. (6)
Add outsourcing filters for CCITT, JPEG, JBIG2, JPEG2k (6)
Define a class for opaflib "commands". (Organize all what is exported from opaflib/init.py) Commands that change the AST should be marked as different from the ones that just produce info (7)
Code the insanely stupid crypto thing of PDF spec. (Trivial decryption of V4/AESV2 already done) (7)(8)
Improve the graph generator so it contains more useful data (8)
