VUE uses AES for encryption

Use of AES encryption

Encrypt and decrypt data transmission—AES.js

first step:

Install crypto-js dependencies in vue

npm install crypto-js --save-dev

Step two:

Create a new AES.js file in the static directory, for example:
file directory example

third step:

Fill in the following code in AES.js

import CryptoJS from "crypto-js";
// npm install crypto-js --save-dev
//随机生成指定数量的32进制key
export default {
  generatekey(num) {
    let library =
      "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
    let key = "";
    for (var i = 0; i < num; i++) {
      let randomPoz = Math.floor(Math.random() * library.length);
      key += library.substring(randomPoz, randomPoz + 1);
    }
    return key;
  },
  //加密
  encrypt(word, keyStr) {
    keyStr = keyStr ? keyStr : "CXMGNcYwTrtsadQmV935ONNXMUycpG1g"; //判断是否存在ksy，不存在就用定义好的key
    var key = CryptoJS.enc.Utf8.parse(keyStr);
    var srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7
    });
    return encrypted.toString();
  },
  //解密
  decrypt(word, keyStr) {
    keyStr = keyStr ? keyStr : "CXMGNcYwTrtsadQmV935ONNXMUycpG1g";
    var key = CryptoJS.enc.Utf8.parse(keyStr);
    var decrypt = CryptoJS.AES.decrypt(word, key, {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7
    });
    return CryptoJS.enc.Utf8.stringify(decrypt).toString();
  }
};

the fourth step:

Introduce where encryption is required

import AES from "@/common/AES.js";

the fifth step:

transfer

//如果是对象/数组的话，需要先JSON.stringify转换成字符串
//调用加密方法
var encrypts = AES.encrypt(JSON.stringify(cars),keys);
//调用解密方法
var dess = JSON.parse(AES.decrypt(encrypts,keys));
console.log(encrypts)
console.log(encrypts.length)
console.log(dess)
