VUE中的 AES加密和解密

import CryptoJS from ‘crypto-js/crypto-js‘

// 默认的 KEY 与 iv 如果没有给
const KEY = CryptoJS.enc.Utf8.parse(‘F697467B14B076F2‘)
const IV = CryptoJS.enc.Utf8.parse(‘0102030405060708‘)

  let hexStr = encrypted.ciphertext.toString().toUpperCase();
  return hexStr

}





//使用
import { Encrypt, Decrypt } from ‘@/utils/crypto‘

let name = ‘123123‘

// 加密
let encryptName = Encrypt(name)

console.log(encryptName)

// 解密
let encryptName = Decrypt(name)

console.log(encryptName)
