@coredomains/cns-namehash

A javascript library for generating CoreDAO Name Service(CNS) namehashes per spec

Available on NPM

Installation

yarn add @coredomains/cns-namehash

Usage

import {namehash,normalize} from '@coredomains/cns-namehash'

const hash = namehash('rickey.cns')
// 

// Support normalizing strings to CNS compatibility
const input = '♫.cns'
const normalized = normalize(input)
// 

If your use in browser,need polyfill Buffer

npm install buffer

import { Buffer } from 'buffer'
globalThis.Buffer = Buffer

Security Warning

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

• faceboоk.cns
• facebook.cns

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.

Notice: If use in browser,you should import buffer
