CRC32 generation using Slicing-by-N algorithm

turbo-crc32

CRC32 generation using Slicing-by-N algorithm. CRC32 and CRC32C algorithms are supported.

Support

Usage

const crc32 = require('turbo-crc32/crc32');
const crc32c = require('turbo-crc32/crc32c');

crc32('123456789')  // 0xcbf43926
crc32c('123456789') // 0xe3069283

// if you want signed integer
crc32('123456789') >> 0 // -873187034

API

• crc32(input: Buffer|String): Number
• crc32c(input: Buffer|String): Number
