CRC RevEng

Posted on by Robin Ding Leave a comment Algorithms, Information Analysis, Mathematics
5.0

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(tm) model of parametrised CRC algorithms.
