> multihash implementation in node.js

This is the [multihash](//github.com/multiformats/multihash) implementation in Node.
It is extended by [js-multihashing](https://github.com/multiformats/js-multihashing)
and [js-multihashing-async](https://github.com/multiformats/js-multihashing-async),
so give those a look as well.

## Install

### Using npm

```bash
> npm install --save multihashes # node the name of the module is multihashes
```

Once the install is complete, you can require it as a normal dependency

```js
const multihashes = require('multihashes')
```

You can require it and use with your favourite bundler to bundle this package in a browser compatible code.

### Using a `<script>` tag

Loading this module through a script tag will make the ```Multihashes``` obj available in the global namespace.

```
<script src="https://unpkg.com/multihashes/dist/index.min.js"></script>
<!-- OR -->
<script src="https://unpkg.com/multihashes/dist/index.js"></script>
```

#### Gotchas

You will need to use Node.js `Buffer` API compatible, if you are running inside the browser, you can access it by `multihash.Buffer` or you can install Feross's [Buffer](https://github.com/feross/buffer).

## Usage

```js
> var multihash = require('multihashes')
> var buf = new Buffer('0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33', 'hex')

> var encoded = multihash.encode(buf, 'sha1')
> console.log(encoded)
<Buffer 11 14 0b ee c7 b5 ea 3f 0f db c9 5d 0d d4 7f 3c 5b c2 75 da 8a 33>

> multihash.decode(encoded)
{ code: 17,
  name: 'sha1',
  length: 20,
  digest: <Buffer 0b ee c7 b5 ea 3f 0f db c9 5d 0d d4 7f 3c 5b c2 75 da 8a 33> }
```
