javascript - 类型错误:generateKeyPairSync 不是函数

Question

我正在尝试使用 generateKeyPairSync() node.js 的crypto 模块的功能。但是我得到一个 typerError 说没有这样的功能。
这很奇怪，因为同一模块的另一个函数 createCipher() 工作得很好!

示例代码如下:

import * as cryp from 'crypto';

export function generate_keys() {
  console.log('hey there!');
  const keyPair = cryp.generateKeyPairSync('rsa', {
    modulusLength: 4096,
    publicKeyEncoding: {
      type: 'spki',
      format: 'pem'
    },
    privateKeyEncoding: {
      type: 'pkcs8',
      format: 'pem',
      cipher: 'aes-256-cbc',
      passphrase: 'top secret'
    }
  });
  console.log(keyPair);
}


function encrypt(data: string) {
  let cipher = cryp.createCipher('aes-256-ecb', 'pass');
  cipher.update(data, 'utf8');
  return cipher.final('hex');
}


// This is working
console.log(encrypt('asa'));

// Getting error - 'generateKeyPairSync is not a function'
generate_keys();

这是完整的控制台输出:
