Multidid

Multidid is a representation strategy for DIDs and DID URLs that is very compact and extensible. It allows any DID method to be represented as a string of bytes. Reference specification.

This library is a multidid utility library to encode and decode multidids to their byte and string representation and convert from did strings to multidid representations.

Installation

npm install --save @didtools/multidid

Usage

import { Multidid } from '@didtools/multidid'
 
const didString = "did:key:z6MkiTBz1ymuepAQ4HEHYSF1H8quG5GLVVQR3djdX3mDooWp#z6MkiTBz1ymuepAQ4HEHYSF1H8quG5GLVVQR3djdX3mDooWp"
 
// Multidid instance from did string
const multidid = Multidid.fromString(didString)
 
// Encode to bytes
multidid.toBytes() 
 
// Decode from bytes to multidid instance
Multidid.fromBytes(bytes)
 
// Encode as a multibase base16 string 
const mdStr = multidid.toMultibase('base16')
console.log(mdStr)

// Multidid instance from base encoded string 
Multidid.fromMultibase(mdStr)
 
// DID string from multidid
multidid.toString()
