(Java to Javascript) Nodejs Crypto Javascript中的javax.crypto.Cipher等效代码

const crypto = require('crypto');

// 加密函数
function encrypt(text, key, iv) {
  const cipher = crypto.createCipheriv('aes-256-cbc', key, iv);
  let encrypted = cipher.update(text, 'utf8', 'hex');
  encrypted += cipher.final('hex');
  return encrypted;
}

// 解密函数
function decrypt(encryptedText, key, iv) {
  const decipher = crypto.createDecipheriv('aes-256-cbc', key, iv);
  let decrypted = decipher.update(encryptedText, 'hex', 'utf8');
  decrypted += decipher.final('utf8');
  return decrypted;
}

// 使用示例
const text = 'Hello, World!';
const key = '0123456789abcdef0123456789abcdef'; // 32字节的密钥
const iv = '0123456789abcdef'; // 16字节的初始向量

const encryptedText = encrypt(text, key, iv);
console.log('加密后的数据:', encryptedText);

const decryptedText = decrypt(encryptedText, key, iv);
console.log('解密后的数据:', decryptedText);
