vue+java AES 加密 解密

后端：

导入aes依赖

vue前端

引入 crypto-js

npm install -S crypto-js

新建全局工具类

import CryptoJS from 'crypto-js/crypto-js'
 
// 默认的 KEY 与 iv 如果没有给
const KEY = CryptoJS.enc.Utf8.parse("1234567890123456");
const IV = CryptoJS.enc.Utf8.parse('1234567890123456');
 
/**
 * AES加密 ：字符串 key iv  返回base64
 */
export function Encrypt(word, keyStr, ivStr) {
  let key = KEY
  let iv = IV
 
  if (keyStr) {
    key = CryptoJS.enc.Utf8.parse(keyStr);
    iv = CryptoJS.enc.Utf8.parse(ivStr);
  }
 
  let srcs = CryptoJS.enc.Utf8.parse(word);
  var encrypted = CryptoJS.AES.encrypt(srcs, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.ZeroPadding
  });
  // console.log("-=-=-=-", encrypted.ciphertext)
  return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
 
}
 
/**
 * AES 解密 ：字符串 key iv  返回base64
 *
 */
export function Decrypt(word, keyStr, ivStr) {
  let key = KEY
  let iv = IV
 
  if (keyStr) {
    key = CryptoJS.enc.Utf8.parse(keyStr);
    iv = CryptoJS.enc.Utf8.parse(ivStr);
  }
 
  let base64 = CryptoJS.enc.Base64.parse(word);
  let src = CryptoJS.enc.Base64.stringify(base64);
 
  var decrypt = CryptoJS.AES.decrypt(src, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.ZeroPadding
  });
 
  var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
  return decryptedStr.toString();
}

秘钥和key和加密方式，填充方式要一致。
