NodeJS 解密数据损坏原始数据

NodeJS Decrypt Data Corrupt Original Data

我使用 AES-266-CBC 加密数据:

const iv = crypto.randomBytes(8).toString('hex');
const encrypt = (text: string): string => {
  log('encrypt');

  const cipher = crypto.createCipheriv('aes-256-cbc', ENCRYPTION_KEY, iv);
  let encrypted = cipher.update(text, 'utf8', 'hex');

  encrypted += cipher.final('hex');
  return encrypted;
};

const decrypt = (text: string): string => {
  log('decrypt');

  const decipher = crypto.createDecipheriv('aes-256-cbc', ENCRYPTION_KEY, iv);
  let decrypted = decipher.update(text, 'hex', 'utf8');
  decrypted += decipher.final('utf8');
  return decrypted;
};

一切都很完美,这意味着如果我使用这个:

const data = JSON.stringify({
  user: 'MHF',
  info: {
    age: 23,
    family: 'HF'
  }
});

const encrypted = encrypt(data);
console.log('encrypted: %s', encrypted);

const decrypted = decrypt(encrypted);
console.log('decrypted: %s', decrypted);

问题是,当我通过 post 请求 http 发送我的加密字符串时,如下所示:

POST {{baseUrl}}/v1/user-register
Content-Type: application/json
Content-Encrypted: AES

{"payLoad": "3f1d1584b0e1976ccea311b5fbe0b2aee1034198a582a3b8bcc773c175e91bb0ceda6b9fb88aff11a892fa7adb83d432"}

我有一些像这样的不正确字符的解密数据:
'r!!(h\x7F!o#L\x19\x10~\x7F"jnfo":{"age":23,"family":"HF"}}'

为什么当我通过加密数据执行 post 请求时我得到这个结果?
这是什么:'r!!(h\x7F!o#L\x19\x10~\x7F"j'?

感谢@Topaco 和@Michael Fehr
生成和使用 IV

是我的大错
