キーペアの生成・保存

DID を作成するのに使用するキーペアを生成してファイルに保存する

touch generate.mjs
generate.mjs
import { DID, generateKeyPair } from "@decentralized-identity/ion-tools";

main().catch((err) => console.error(err));

async function main() {
  const keyPair = await generateKeyPair();
  console.log(JSON.stringify(keyPair, null, 2));
}

node generate.mjs > key.json

@decentralized-identity/ion-tools は ESM なので package.json に "type": "module" を追記するかファイルの拡張子を .mjs にする

実行結果の例は下記の通り

key.json
{
  "publicJwk": {
    "kty": "EC",
    "crv": "secp256k1",
    "x": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "y": "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
  },
  "privateJwk": {
    "kty": "EC",
    "crv": "secp256k1",
    "x": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "y": "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy",
    "d": "ddddddddddddddddddddddddddddddddddddddddddd"
  }
}

DID URI の取得

touch uri.mjs
uri.mjs
import { DID } from "@decentralized-identity/ion-tools";
import fsPromises from "fs/promises";

main().catch((err) => console.error(err));

async function main() {
  const keyPair = await fsPromises.readFile("key.json", "utf8");
  const { publicJwk } = JSON.parse(keyPair);
  const did = new DID({
    content: {
      publicKeys: [
        {
          id: "key-1",
          type: "EcdsaSecp256k1VerificationKey2019",
          publicKeyJwk: publicJwk,
          purposes: ["authentication"],
        },
      ],
      services: [
        {
          id: "domain-1",
          type: "LinkedDomains",
          serviceEndpoint: "https://foo.example.com",
        },
      ],
    },
  });

  const uri = {
    long: await did.getURI(),
    short: await did.getURI('short'),
  }

  console.log(JSON.stringify(uri, null, 2));
}

node uri.mjs > uri.json
uri.json
{

DID の short の方を Universal Resolver を使って解決してみる

当然だがまだアンカーしていないので解決できない

DID URI の解決

touch resolove.mjs

main().catch((err) => console.error(err));

async function main() {

  const { didDocument } = await resolve(long);

勝手に標準出力にデータを出すのはご勘弁いただきたい、何かを設定すれば OFF にできるのだろうか

今のところ Universal Resolver では表示されない、時間が経てば表示されるようになる？

薄田達哉 / tatsuyasusukida薄田達哉 / tatsuyasusukida

3つの鍵が必要というけれど

Sidetreeでは、以下の3つの鍵ペアを生成する。

署名鍵：DID自体に関連付けられるメインの鍵で、DIDのユースケースにおける署名や認証に用いる鍵。
Update Key：DIDの更新とUpdate Key自体の更新に使用する鍵。
Recovery Key：DIDの更新、失効とUpdate Key、Recovery Key自体の更新に使用する鍵。

ion-tools のソースコードを読むと確かにそんな感じのことが書かれている

ion-tools/src/did.js
      case 'create':
      default:
        return IonRequest.createCreateRequest({
          recoveryKey: op.recovery.publicJwk,
          updateKey: op.update.publicJwk,
          document: op.content
        });

同じリクエストがあるのでダメと言われる

しばらく待ってみよう

薄田達哉 / tatsuyasusukida薄田達哉 / tatsuyasusukida

待てど暮らせど

serviceEndpoint が削除されない

キーが間違っているのだろうか

base64url("#domain-1") の部分を "domain-1" に変えてみたり色々やったけどダメだった

serviceEndpoint の追加ならできるかと思って下記も試してみた

servicesToAdd: [
  {
    id: "domain-2",
    type: "LinkedDomains",
    serviceEndpoint: "https://bar.example.com",
  },
],

しかし今のところ反映されている様子はない

秘密鍵とかが間違っている？

いずれにしても結果が反映されるまでに時間がかかるのは辛い、長いと半日から1日くらいかかる

結局 Sidetree の仕様書を読んでいる

https://identity.foundation/sidetree/spec/

これはこれで面白い

更新リクエスト生成も少し変更

update-request.ts
import { IonRequest, LocalSigner } from "@decentralized-identity/ion-sdk";

async function main() {
  const keyPair = require("./generate-keypair.json");
  const keyPairNext = require("./generate-keypair-for-update.json");
  const updateRequest = await IonRequest.createUpdateRequest({
    didSuffix: 'EiDTaXiorXIqIBa4DQQxS9MZXpTqHE-4vvtTnE_NcPkPWA',
    updatePublicKey: keyPair.update.publicJwk,
    nextUpdatePublicKey: keyPairNext.update.publicJwk,
    signer: LocalSigner.create(keyPair.update.privateJwk),
    servicesToAdd: [
      {
        id: 'domain-2',
        type: "LinkedDomains",
        serviceEndpoint: "https://foo.example.com",
      },
    ],
  });

  console.log(JSON.stringify(updateRequest, null, 2));
}

main().catch((err) => {
  console.error(err);
});

}

わかりにくいけど updateCommitment が変更されている

Sidetree の仕様書によるとコミットメントとは JWK 形式の公開鍵を正規化（フィールド準備を辞書順にするなど）してから2回 SHA-256 ハッシュを計算するようだ

ちゃんと service に #domain-2 が増えている

結局更新する度に鍵を変える必要があるというのが正解だった
