CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 71 preset algorithms, or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from sufficient correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Compliant with Ross Williams' Rocksoft™ model of parametrised CRC algorithms.
CRC RevEng was first released on 5 January 2011 at regregex.bbcmicro.net. It is a port and expansion of a Perl script,
crcbfs.pl, released in 2007. This SourceForge project was created on 28 May 2012.
CRC RevEng is released under the terms of the GNU General Public Licence, version 3 (GPLv3).
The latest version of CRC RevEng is 1.1.4, released on 14 October 2013. The latest changes are:
CRC-13/BBCand six cdma2000 algorithms from the CRC catalogue.
