The IPID DID method implementation in JavaScript.
$ npm install did-ipidThis library is written in modern JavaScript and is published in both CommonJS and ES module transpiled variants. If you target older browsers please make sure to transpile accordingly.
import createIpid, { getDid } from 'did-ipid';
const did = await getDid(pem);
//=> Returns the DID associated to a private key in PEM format.
const ipid = await createIpid(ipfs);
const didDocument = await ipid.resolve('did:ipid:QmUTE4cxTxihntPEFqTprgbqyyS9YRaRcC8FXp6PACEjFG');
//=> Resolves a DID and returns the respective DID Document.
const didDocument = await ipid.create(pem, (document) => {
const publicKey = document.addPublicKey({
type: 'RsaVerificationKey2018',
publicKeyHex: '02b97c30de767f084ce3080168ee293053ba33b235d7116a3263d29f1450936b71',
});
const authentication = document.addAuthentication(publicKey.id);
const service = document.addService({
id: 'hub',
type: 'HubService',
serviceEndpoint: 'https://hub.example.com/',
});
});
//=> Creates a new DID and the corresponding DID Document based on the provided private key pem.
//=> The DID Document is published with the added publicKey, authentication and service.
const didDocument = await ipid.update(pem, (document) => {
document.removeService('hub');
document.addService({
id: 'messages',
type: 'MessagingService',
serviceEndpoint: 'https://example.com/messages/8377464',
});
});
//=> Updates a DID Document based on the DID associated to the provided private key pem.
//=> The DID Document is published without the `hub` service and with a new one called `messages`. Returns the DID associated to a private key in PEM format.
Type: string
A private key in PEM format.
Supported formats: pkcs1-pem or pkcs8-pem.
Example:
-----BEGIN RSA PRIVATE KEY-----
MIICXQIBAAKBgQDCQZyRCPMcBPL2J2SuI2TduR7sy28wmcRzfj8fXQTbj1zJURku
...
-----END RSA PRIVATE KEY-----An IPFS node is required to create an IPID instance. Please be sure to check js-ipfs, the JavaScript implementation of the IPFS protocol, to learn how to create one.
There is currently only one option available during the creation of an IPID instance. The lifetime option defines the duration of the DID document availability.
Example:
import createIpid from 'did-ipid';
const ipid = await createIpid(ipfs, { lifetime: '24h' });Notes:
- Please make sure that the IPFS node is
readyto use. - This package uses the Key Management provided by IPFS. So during the creation of the node a password must be defined, as an option, to encrypt/decrypt your keys.
