使用Node.js crypto生成多对公钥/私钥

如何在Node.js中使用crypto生成多对密钥

在node.js中，有以下代码用于生成对。但是如果我将名称更改为

{key，public_key}

然后尝试

console.log

它们，它将打印

未定义的
。但是，我需要两对，不能用相同的名称运行它两次，或者它告诉我它们是以前定义的。有没有其他方法可以使用加密生成另一对

const { publicKey, privateKey } = generateKeyPairSync('rsa', {
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret'
  }
});

关键字：未定义
发布密钥：未定义

或：

您不能在一行中使用两个接收器函数，因为我们必须等待这两个函数都出现，然后再打印。因此，最好使用回调函数来获取答案并加入外部变量

let public1, public2;
let private1, private2;

const { generateKeyPair } = require('crypto');
generateKeyPair('rsa', {
    modulusLength: 4096,
    publicKeyEncoding: {
        type: 'spki',
        format: 'pem'
    },
    privateKeyEncoding: {
        type: 'pkcs8',
        format: 'pem',
        cipher: 'aes-256-cbc',
        passphrase: 'top secret'
    }
}, (err, publicKey, privateKey) => {
    public1 = publicKey;
    private1 = privateKey;
    generateKeyPair('rsa', {
        modulusLength: 4096,
        publicKeyEncoding: {
            type: 'spki',
            format: 'pem'
        },
        privateKeyEncoding: {
            type: 'pkcs8',
            format: 'pem',
            cipher: 'aes-256-cbc',
            passphrase: 'top secret'
        }
    }, (err, publicKey1, privateKey1) => {
        public2 = publicKey1;
        private2 = privateKey1;
    });
});
console.log("public1 : ", public1)
console.log("private1 : ", private1)
console.log("public2 : ", public2)
console.log("private2 : ", private2)

在销毁分配过程中，您可以按如下方式将
publicKey、privateKey
属性分配给：

const { generateKeyPairSync } = require('crypto');

const keyOptions = [{
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret 1'
  }
}, {
  modulusLength: 2048,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret 2'
  }
}]

const [
  { publicKey: publicKey1, privateKey: privateKey1 },
  { publicKey: publicKey2, privateKey: privateKey2 }
] = keyOptions.map(options => generateKeyPairSync('rsa', options))

console.log(
  publicKey1,
  privateKey1,
  publicKey2,
  privateKey2
)

const { generateKeyPairSync } = require('crypto');

const keyOptions = [{
  modulusLength: 4096,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret 1'
  }
}, {
  modulusLength: 2048,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem',
    cipher: 'aes-256-cbc',
    passphrase: 'top secret 2'
  }
}]

const [
  { publicKey: publicKey1, privateKey: privateKey1 },
  { publicKey: publicKey2, privateKey: privateKey2 }
] = keyOptions.map(options => generateKeyPairSync('rsa', options))

console.log(
  publicKey1,
  privateKey1,
  publicKey2,
  privateKey2
)
