This catalogue lists cyclic redundancy check algorithms fully specified in the literature or known to be in use in the field. The algorithms are specified as parameter sets in the Rocksoft™ Model set out in Ross Williams' 1993 paper "A Painless Guide to CRC Error Detection Algorithms". Each algorithm is supported by references providing evidence and some incidental context of its use. CRC RevEng, an arbitrary-precision CRC calculator and algorithm finder, serves as a reference implementation of the catalogue and likewise, the catalogue provides supporting evidence for the presets in the calculator.
The CRC catalogue was first published on 30 March 2005. This edition (first published 4 July 2012) has been expanded with more complete citations, and reformatted for more reliable rendering.
To reduce the file sizes the catalogue has been split into four parts. A complete version is also available:–
Alternatively, you can jump to the algorithms of a specific width through the summary:
