Installation

You can also install js-crc by using Bower.

bower install js-crc

For node.js, you can use this command to install:

npm install js-crc

Usage

You could use like this:

crc32('Message to hash');
crc16('Message to hash');

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

var crc32 = require('js-crc').crc32;
var crc16 = require('js-crc').crc16;

It supports AMD:

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

## Example
```JavaScript
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
