前端des加密，后端des解密

1. 使用 crypto-js.min.js 的des加密方式加密数据
2. 下载地址 https://cdnjs.com/libraries/crypto-js
3. 前端加密方式
    

   // 加密方法
   function Encrypt(word,skey) {
       var keyHex = CryptoJS.enc.Utf8.parse(skey);
       let encrypted = CryptoJS.AES.encrypt(word, keyHex, {
           mode: CryptoJS.mode.ECB,
           padding: CryptoJS.pad.Pkcs7
       });
       return encrypted.toString()
   }

    

4. 后端解密方式
    

       /**

        * @param sKey
        * @return
        * @throws Exception
        */
       public static String decrypt_loginInfo(String hexStr,String key) throws Exception {
           byte[] contentNew = Base64.decodeBase64(hexStr);
           SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");
           Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
           cipher.init(Cipher.DECRYPT_MODE, skeySpec);
           return new String(cipher.doFinal(contentNew));
       }
   
   
        /**
        * 随机生成加密串 length加密串长度
        * @return
        */
       public static String generateRandomKey(int length){
           String base = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789/=+";
           Random random = new Random();
           StringBuffer sb = new StringBuffer();
           for (int i = 0; i < length; i++) {
               int number = random.nextInt(base.length());
               sb.append(base.charAt(number));
           }
           return sb.toString();
       }
