## Vue 的 AES 加密解密工具类

```javascript
import CryptoJS from 'crypto-js'

const key = '0123456789abcdef'

export function encrypt(content) {
  const ciphertext = CryptoJS.AES.encrypt(content, CryptoJS.enc.Utf8.parse(key), {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
  })
  return CryptoJS.enc.Base64.stringify(ciphertext.ciphertext)
}

export function decrypt(content) {
  const bytes = CryptoJS.AES.decrypt(content, CryptoJS.enc.Utf8.parse(key), {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
  })
  return bytes.toString(CryptoJS.enc.Utf8)
}

// 调用示例
const content = 'Hello World'
console.log('加密前：', content)
const encryptContent = encrypt(content)
console.log('加密后：', encryptContent)
const decryptContent = decrypt(encryptContent)
console.log('解密后：', decryptContent)
