There are a few differences, specifically, this library uses [JavaScript BigInts](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt) to perform calculations. As a result, it leads to a simplification of the code, but the response can't be directly used as an integer. ## CRC Models This library currently supports the 8, 16, 32, and 64 Bit CRC Algorithms listed on the [RevEng CRC Catalogue](http://reveng.sourceforge.net/crc-catalogue/). More algorithms may work, but has not yet been tested. See the list of algorithms below for a complete list. Each of the algorithms listed on that page include check value that is used to test the CRC calculation against the string `123456789`. ## Usage ``` const { CRC, CRCModel, } = require('crc-multi'); const model = CRCModel.GetModel('CRC-16/ARC'); /* { width: 16, poly: 32773n, init: 0n, refin: true, refout: true, xorout: 0n, check: 47933n, residue: 0n, name: 'CRC-16/ARC' } */ const crc = new CRC(model); const check = crc.compute(Buffer.from('123456789')); // 47933n assert(check === BigInt('0xbb3d')); ``` ## Algorithm List | Algorithm(s) | Width | Check | Poly | Init | RefIn | RefOut |
