js给视频地址加密

const CryptoJS = require('crypto-js');

// 密钥和初始向量（IV），需要妥善保管
const secretKey = 'your-secret-key';
const iv = CryptoJS.lib.WordArray.random(16);

// 加密函数
function encryptVideoUrl(url) {
  const encrypted = CryptoJS.AES.encrypt(url, secretKey, { iv: iv });
  return encrypted.toString();
}

// 解密函数
function decryptVideoUrl(encryptedUrl) {
  const decrypted = CryptoJS.AES.decrypt(encryptedUrl, secretKey, { iv: iv });
  return decrypted.toString(CryptoJS.enc.Utf8);
}

// 示例
const originalUrl = 'https://example.com/video.mp4';
const encryptedUrl = encryptVideoUrl(originalUrl);
console.log('Encrypted URL:', encryptedUrl);

const decryptedUrl = decryptVideoUrl(encryptedUrl);
console.log('Decrypted URL:', decryptedUrl);
