Web前后端笔记-vue cli及java进行AES加解密- 前端开发

这里我直接贴代码了。

vue cli中，要先导入

npm install crypto-js

vue代码如下：


import axios from 'axios'
import cryptoJS from "crypto-js/crypto-js";
 
axios.defaults.timeout = 35 * 1000;
 
/**
 *  Get方法
 * @param {*} url
 * @param {*} params
 */
export function fetch(url, params = {}) {
 
  return new Promise((resolve, reject) => {
 
    params['timestamp'] = new Date().getTime();
 
    let oriInfo = "";
    for (let key in params) {
 
      oriInfo += params[key] + "$";
    }
    let paraString = oriInfo.substr(0, oriInfo.length - 1);
    params['signature'] = this.$md5(paraString);
    let key = params['signature'].substring(0, 16);
    let shieldStr = encrypt(params['signature'], key)
    console.log("shield:" + shieldStr);
    console.log("origin:" + decrypt(shieldStr, key))
    params['shield'] = shieldStr;
 
    axios.get(url, {
 
      params: params
    }).then(response => {
 
      resolve(response);
    }).catch(err => {
 
      reject(err)
    })
  })
}
 
 
export function post(url, data = {}) {
 
  return new Promise((resolve, reject) => {
 
    axios.post(url, data)
      .then(response => {
 
          resolve(response);
        },
        err => {
 
          reject(err);
        })
  })
}
 
 
//aes加密
export function encrypt(word, keyStr) {
 
  keyStr = keyStr ? keyStr : 'QWERTASDFGZXCVBN';
  let key = cryptoJS.enc.Utf8.parse(keyStr);
  let srcs = cryptoJS.enc.Utf8.parse(word);
  let encrypted = cryptoJS.AES.encrypt(srcs, key, {mode: cryptoJS.mode.ECB, padding: cryptoJS.pad.Pkcs7})
  return encrypted.toString();
}
 
//aes解密
export function decrypt(word, keyStr) {
 
  keyStr = keyStr ? keyStr : 'QWERTASDFGZXCVBN';
  let key = cryptoJS.enc.Utf8.parse(keyStr);
  let decrypt = cryptoJS.AES.decrypt(word, key, {mode: cryptoJS.mode.ECB, padding: cryptoJS.pad.Pkcs7});
  return cryptoJS.enc.Utf8.stringify(decrypt).toString();
}

上面这个vue的，AES用的是signature前16位做的AES。

下面是java端：


public class AESUtil {
 
    public static String decrypt(String content, String key) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException, UnsupportedEncodingException {
 
        //Key k = toKey(Base64.decodeBase64(key));
        Key k = toKey(key.getBytes());
        byte[] encoded = k.getEncoded();
        SecretKeySpec aes = new SecretKeySpec(encoded, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.DECRYPT_MODE, aes);
 
        byte[] bytes = cipher.doFinal(Base64.decodeBase64(content));
 
        return new String(bytes, "UTF-8");
    }
 
    public static String encrypt(String data, String key) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, UnsupportedEncodingException, BadPaddingException, IllegalBlockSizeException {
 
        //Key k = toKey(Base64.decodeBase64(key));
        Key k = toKey(key.getBytes());
        byte[] encoded = k.getEncoded();
        SecretKeySpec aes = new SecretKeySpec(encoded, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, aes);
        byte[] bytes = cipher.doFinal(data.getBytes("UTF-8"));
        return Base64.encodeBase64String(bytes);
    }
 
    private static Key toKey(byte[] key){
 
        SecretKeySpec aes = new SecretKeySpec(key, "AES");
        return aes;
    }
 
}
