Usage

You could use like this:

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

1var crc16 = require('js-crc-update').crc16;
2var crc32 = require('js-crc-update').crc32;
3var crc64 = require('js-crc-update').crc64; // coming soon

It supports AMD:

1require(['your/path/crc.js'], function (crc) {
2    var crc16 = crc.crc16;
3    var crc32 = crc.crc32;
4    var crc64 = crc.crc64; // coming soon
5    // ...
6});

Example

1crc32('The quick brown fox jumps over the lazy dog'); // 414fa339
2crc32('The quick brown fox jumps over the lazy dog.'); // 519025e9

4// It also supports byte `Array`, `Uint8Array`, `ArrayBuffer` input:
5crc32([0]); // d202ef8d
6crc32(new Uint8Array([0])); // d202ef8d
