A javascript library for generating Wanchain Name Service (WNS) namehashes per spec.
npm install wan-wns-namehash -S
var namehash = require('wan-wns-namehash')
var hash = namehash.hash('foo.wan')
// '0xde9b09fd7c5f901e23a3f19fecc54828e9c848539801e86591bd9801b019f84f'
// Also supports normalizing strings to WNS compatibility:
var input = getUserInput()
var normalized = namehash.normalize(input)WNS Supports UTF-8 characters, and so many duplicate names are possible. For example:
- faceboоk.wan
- facebook.wan
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.
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).
