CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any of the 102 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 License, version 3 and later (GPLv3+).
The latest version of CRC RevEng is 1.5.2, released on 20 June 2017. The latest changes are:
CRC-21/CAN-FD, from the CRC Catalogue.
Enhanced Zip archive available for RISC OS. For other operating systems please view the latest releases.
