Although not strictly for forensic purposes, '''visualization tools''' such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.

Hi, I'm the author of [http://hachoir.org/ Hachoir], a generic framework for binary file manipulation. I don't know if I can add it in your wiki. I prefer to have your review first :-)
+
== Applications ==
 +
Most of these applications can be used to do visualization
  
Hachoir supports many file formats (more than 60 formats) and have many features:
+
; Crystal Space 3D
* Fault tolerant parser (truncated/buggy file or buggy parser)
+
* Smart syntax: you don't have to care about endian or charset, and you can mix byte and bit fields
+
* Few functions to modify files
+
* File recognition using header/footer in a disk image (in any file) with few false positive (each file is checked using the parser)
+
* Written in Python: OS independant and easy to script/extend
+
* curses, wxWidgets and Gtk interfaces
+
* Many programs based on hachoir-core and hachoir-parser:
+
  * hachoir-strip: remove metadata and other "useless" informations
+
  * hachoir-grep: find substring in a binary file (using hachoir parsers: so search is Unicode aware)
+
  * hachoir-subfile: find all subfiles in a file
+
  * etc.

Although not strictly for forensic purposes, visualization tools such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.

Programming Languages and Developer Toolkits

If you are building forensic tools, you probably want to start with one of these:

Java

Advantage: Portable and lots of good documentation out there.

Disadvantage: Programs are a bit verbose, and only offers about 1/2 the performance of C

Python

Advantage: Portable

Disadvantage: Python is one of the slowest modern languages around and doesn't work well with big data sets.

  • Python with Tk
  • Python with matplotlib
  • Python with wxWidgets (not installed by default)
  • NetworkX, a pure Python network layout program which uses matplotlib to do the actual graphing.

Processing.org

Advantage: Programming language specifically developed for visualization; compiles to java byte code
Disadvantage: Very oddball
