The IPNS DID Kit is a JavaScript library designed to facilitate the creation, management, and utilization of decentralized identities (DIDs) based on IPNS (InterPlanetary Name System). This library enables users to create and maintain DIDs that are compatible with IPFS (InterPlanetary File System) pinning platforms and supports DNSLink, enhancing web compatibility and DNS-based resolution.

• DID Creation and Management: Generate and manage DID documents with support for multiple cryptographic proof methods, including secp256k1.
• Persistence on IPNS and IPFS: Persist DID documents on IPNS and IPFS to ensure decentralized and reliable storage.
• Compatibility with DNSLink: Integrate with DNSLink to facilitate DNS-based resolution of DIDs, linking DIDs with human-readable domain names.
• Audit and Version Control: Track changes and revisions to DID documents, providing a method for auditing document history.
• Dynamic Service Endpoint Management: Modify and manage service endpoints associated with a DID, allowing the DID to interact with various decentralized services.
• Cryptographic Functionality: Generate random keys, sign messages, verify signatures, and more, all using built-in cryptographic functions.

To install the library, you can use npm/yarn:

npm install @did-ipns/kit
yarn install @did-ipns/kit

import IpnsDidKit from '@did-ipns/kit';
import { createHeliaHTTP } from "@helia/http";
import { trustlessGateway } from "@helia/block-brokers";
import { delegatedHTTPRouting } from "@helia/routers";

const helia = await createHeliaHTTP({
    blockBrokers: [
        trustlessGateway({
            gateways: ["http://127.0.0.1:8080"],
        }),
    ],
    routers: [delegatedHTTPRouting("http://127.0.0.1:8080/routing/v1")],
});
const ipnsDidKit = new IpnsDidKit(helia);

const privateKey = ipnsDidKit.generateRandomKey();
const didDocument = ipnsDidKit.create('your-unique-id', privateKey);

const signature = ipnsDidKit.sign('your-did-id', privateKey, 'message-to-sign');
const isValid = ipnsDidKit.verifySignature('your-did-id', publicKey, signature, 'message-to-sign');

didDocument = ipnsDidKit.modifyServiceEndpoint(didDocument, 'serviceId', 'type', 'newEndpoint');
