crc32-universal

CRC32 slice-by-16 implementation in JS with an optional native binding to speed it up even futher. When used with Webpack/Browserify etc, it bundles the JS version.

npm install crc32-universal

JS version is provided by https://gist.github.com/101arrowz/e58695f7ccfdf74f60ba22018093edea (thank you to @andrewosh for finding that) and the C version is provided by https://github.com/stbrumme/crc32.

For payloads smaller than 256 bytes the JS version is always used as that's faster than context switching to C (Javascript is really fast!).

PR welcome that support the SSE4/Neon optimisations for Intel/ARM for even faster speedup.

Usage

const crc32 = require('crc32-universal')
const uint = crc32(Buffer.from('hello'))
console.log(uint) // 907060870
