# Eth ENS Namehash (Fork)

A javascript library for generating Ethereum Name Service (ENS) namehashes per [spec](https://github.com/ethereum/EIPs/issues/137).

[Available on NPM](https://www.npmjs.com/package/@ensdomains/eth-ens-namehash)

## Installation

`npm install @ensdomains/eth-ens-namehash -S`

## Usage

```javascript
var namehash = require('@ensdomains/eth-ens-namehash')
var hash = namehash.hash('foo.eth')
// '0xde9b09fd7c5f901e23a3f19fecc54828e9c848539801e86591bd9801b019f84f'

// Also supports normalizing strings to ENS compatibility:
var input = getUserInput()
var normalized = namehash.normalize(input)
```

## Security Warning

ENS Supports UTF-8 characters, and so many duplicate names are possible. For example:

- faceboоk.eth
- facebook.eth

The first one has non-ascii chars. (control+F on this page and search for facebook, only the second one will match).

namehash.normalize() doesn't automagically remap those, and so other precautions should be taken to avoid user phishing.

## Development

This module supports advanced JavaScript syntax, but exports an ES5-compatible module. To re-build the exported module after making changes, run `npm run bundle` (must have [browserify](http://browserify.org/) installed).

-												Version 2: Add normalize method

Is a major breaking change, because we now export an object instead of a lone function.

Fixes #1
