背景情况

(从 digitalbazaar/x25519-key-agreement-key-2020 页:1 以提供类型脚本兼容性。 )

用于与 crypto-ld >= 5.0。 。 。 .

为了真正用这些密钥进行加密,我们建议您使用 页:1 minimal-cipher 图书馆.

这是一个低级库,用于生成并序列化 X25519 (Curve25519) 密钥对( 使用) nacl.box 盖下.

另见(相关规格):

• 链接数据证明
• 链接数据加密成套登记

安装

需要节点.js 12+

在当地安装(用于开发):

git clone https://github.com/digitalcredentials/x25519-key-agreement-key-2020.git
cd x25519-key-agreement-key-2020
npm install

使用量

导入中 :

const {X25519KeyAgreementKey2020} = require('@digitalcredentials/x25519-key-agreement-key-2020');

// Or, if you're testing code in the interactive Node CLI, right in this repo:
const {X25519KeyAgreementKey2020} = require('./');

生成中 :

const keyPair = await X25519KeyAgreementKey2020.generate({
  controller: 'did:example:1234'
});
// ->
{
  "id": "did:example:1234#z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "controller": "did:example:1234",
  "type": "X25519KeyAgreementKey2020",
  "publicKeyMultibase": "z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "privateKeyMultibase": "z3weeMD56C1T347EmB6kYNS7trpQwjvtQCpCYRpqGz6mcemT"
}

将公钥序列化 :

keyPair.export({publicKey: true});
// ->
{
  "id": "did:example:1234#z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "controller": "did:example:1234",
  "type": "X25519KeyAgreementKey2020",
  "publicKeyMultibase": "z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM"
}

私人和公共钥匙的序列:

// a different key pair than the previous example
await keyPair.export({publicKey: true, privateKey: true})
// ->
{
  "id": "did:example:1234#z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "controller": "did:example:1234",
  "type": "X25519KeyAgreementKey2020",
  "publicKeyMultibase": "z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "privateKeyMultibase": "z3weeMD56C1T347EmB6kYNS7trpQwjvtQCpCYRpqGz6mcemT"
}

切换 :

// Loading public key only
const keyPair = await X25519KeyAgreementKey2020.from({
  "id": "did:example:1234#z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM",
  "controller": "did:example:1234",
  "type": "X25519KeyAgreementKey2020",
  "publicKeyMultibase": "z6LSeRSE5Em5oJpwdk3NBaLVERBS332ULC7EQq5EtMsmXhsM"
});
