Class: PeerDIDMethod

Defined in: packages/lib/sdk/src/castor/methods/peer/index.ts:41

DID method implementation for did:peer (algorithm 2).

Creates peer DIDs from authentication and key-agreement keys and verifies signatures by resolving the DID Document locally.

const peer = new PeerDIDMethod();
const did = await peer.create({
  keys: {
    AUTHENTICATION_KEY: [authSK],
    KEY_AGREEMENT_KEY: [agreementSK],
  },
  services: [service],
});
