afflib-tools

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.

This package provides the AFF Toolkit, that 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 multiple 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 multiple 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 a XML representation of a disk image’s metadata (for example, acquisition time or the serial number of the acquisition device).
  • Produce a XML “diskprint” which allows a disk image to be rapidly fingerprinted without having the computer the SHA1 of the entire disk.

The AFF Toolkit provides these executables: affcat, affcompare, affconvert, affcopy, affcrypto, affdiskprint, affinfo, affix, affrecover, affsegment, affsign, affstats, affuse, affverify and affxml.
