{{Digital forensics}}

The Open Computer Forensics Architecture is distributed primary as a [[back end]] architecture for the [[Linux]] platform. The results of the digital media processing are stored in a [[PostgreSQL]] database, a custom [[Content-addressable storage]] or CarvFS based data repository and a [[Lucene]] index. A [[front end]] for OCFA has not been made publicly available due to licencing issues.

[[Category:Digital forensics software]]

OCFA comes with a small set of modules that integrate some common open source tools and libraries into the architecture. These include modules for integration of [[The Sleuth Kit]], Scalpel, Photorec, libmagic,

[[Category:Data recovery]]

[[GNU Privacy Guard]], [[objdump]], exiftags, zip, [[7-zip]], [[tar]], [[gzip]], [[bzip2]], [[rar]], [[antiword]], qemu-img, mbx2mbox, strings, many perl modules for mail and dbx processing, libewf and others.

[[Category:Distributed computing architecture]]

While these standard modules provide a reasonable environment for processing digital media, most of the power of OCFA comes from its extendability. OCFA comes with libraries for building your own modules in [[C++]] or [[Java]].

[[Category:Software using the GNU Lesser General Public License]]

Both the Java and C++ library provide an API for building custom OCFA modules for integration of other tools or libraries into the computer forensics process. Basic modules like this can produce derived data and add extracted meta-data to both the input data and the derived data. The C++ library also provides a second more advanced API for building modules that produce derived output with meta data at more than one level deep.
