npm install js-crc

Usage

You could use like this:

crc16('Message to hash');
crc32('Message to hash');
crc64('Message to hash'); // coming soon

If you use node.js, you should require the module first:

var crc16 = require('js-crc-update').crc16;
var crc32 = require('js-crc-update').crc32;
var crc64 = require('js-crc-update').crc64; // coming soon

It supports AMD:

require(['your/path/crc.js'], function (crc) {
    var crc16 = crc.crc16;
    var crc32 = crc.crc32;
    var crc64 = crc.crc64; // coming soon
    // ...
});

Example

crc32('The quick brown fox jumps over the lazy dog'); // 414fa339
crc32('The quick brown fox jumps over the lazy dog.'); // 519025e9

// It also supports byte `Array`, `Uint8Array`, `ArrayBuffer` input:
crc32([0]); // d202ef8d
crc32(new Uint8Array([0])); // d202ef8d
