CRC16

Native node addon to calculate CRC16 values.

Installation

npm i crc16 --save

NOTE

If your intention is to use this to calculate redis slots then please use https://github.com/Salakar/cluster-key-slot - it's a pure JS implementation I wrote that is much faster than doing it natively.

Usage

CRC16(stringOrBuffer, [optional] encoding)

• stringOrBuffer: String or a buffer. If a string is provided it will automatically be converted to a buffer.
• encoding: Used for string to buffer conversion - only when a string is provided in stringOrBuffer

var CRC16 = require('crc16');
console.log(CRC16('some_value'));
console.log(CRC16('0d0103588990501766460026', 'hex'));
 
// calculate a redis hash slot
console.log(CRC16('key') & 16383);
