Replace pdfparser with a more robust and complete parsing of a PDF
|
|
|
|
Optimize the crack and crypto-routines for greater performance
|
|
|
|
Add support for third-party security handlers
|
|
|
|
Add real permutation-support. Maybe John the Ripper could be a
|
|
source of inspiration?
|
|
|
|
Add support for masked passwords, when we already knows parts of the password
|
|
|
|
|
|
Furthermore:
|
|
|
|
Replace pdfparser with a complete representation of the structure of a
|
|
PDF-file that can be used to find information and more importantly, can be
|
|
written out again to a file.
|
|
For this we need to understand/represent objects (indirect and direct), the
|
|
file structure (lineraized and standard) and xreftables with trailers.
|
|
We need to be able to update/fix the xreftables when writing it.
|
|
We also need support for LZM-compression that is used for many streams.
|
|
|
|
When the above item is done there is nothing stopping us from adding complete
|
|
RC4-keyspace search and decrypt without having to bother cracking the
|
|
passwords. An example of this search can be viewed at:
