The Advanced Forensic Format (AFF) is on-disk format for storing

computer forensic information. Critical features of AFF include:



  - AFF allows you to store both computer forensic data and associated

    metadata in one or more files. 



  - AFF allows files to be digital signed, to provide for

    chain-of-custody and long-term file integrity.



  - AFF allows for forensic disk images to stored encrypted and

    decrypted on-the-fly for processing. This allows disk images

    containing privacy sensitive material to be stored on the Internet.



  - AFF is an open format unencumbered by copyright or patent

    protection. The AFFLIB library that implements AFF is available

    for use in both Open Source and proprietary tools.



AFF Library and Toolkit is a set of programs for working with computer

forensic information. Using these tools you can:



 * Interconvert disk images between a variety of formats, including:



   - raw or "dd" 

   - splitraw (in which a single image is split between mulitple files)

   - AFF format (in which the entire disk image is stored in a single file.)

   - AFD format (in which a disk image is stored in mulitple AFF files

     stored in a single directory.)

   - AFM format (in which an AFF file is used to annotate a raw file.)



 * Compare disk images and report the data or metadata that is different. 



 * Copy disk images from one location to another, with full

   verification of data, metadata, and the automatic generation of a

   chain-of-custody segment.



 * Find errors in an AFF file and fix them.



 * Print information about a file.



 * Print detailed statistics about a file



 * Generate an XML representation of a disk image's metadata (for

   example, acquisition time or the serial number of the acquisition

   device.)



 * Produce an XML "diskprint" which allows a disk image to be rapidly

   fingerprinted without having the computer the SHA1 of the entire

   disk.



AFFLIBv3 implements version 3 of the AFF format. This version is

currently in maintenance mode while work on AFFv4 continues. Key

differences between AFFv3 and AFFv4 include:



 * Whereas AFFv3 uses a purpose-built container file format, AFFv4 is

   based on ZIP64.



 * Whereas AFFv3 is licensed with a four-part Berkeley license, AFFv4

   is licensed an approved Open Source license.



AFFLIB and Toolkit is provided in source code form for Linux, MacOS

and Windows. We have also created a Windows zipfile that contains:



 * precompiled versions of the AFFLIB tools and all of the libraries

   necessary to run them.



 * bulk_extractor.jar - A Java port of our system that automatically

   extracts email addresses, dates, and other information from a file

   and produces a histogram of the contents.

AFFLIB with SleuthKit:



TSK officially supports a subset of the image formats that AFFLIB

supports.  To use the other image formats, specify the image type as

"afflib".  For example:



# fls -o 63 -i afflib foo.vmdk
