Eth ENS Namehash (Fork)
A javascript library for generating Ethereum Name Service (ENS) namehashes per spec.
Installation
npm install @ensdomains/eth-ens-namehash -S
Usage
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 installed).
