How to use PHP and Vue.js to develop best practices for preventing data leakage and modification

In the current Internet era, data security has always been a concern. Whether it is an individual user or an enterprise organization, measures need to be taken to prevent data leakage and modification. During the development process, we can leverage the power of PHP and Vue.js to enhance data security. This article describes how to use these two technologies to develop best practices for protecting against data breaches and modifications, and provides corresponding code examples.

1. Use appropriate authentication and authorization mechanisms

In system development, it is very important to use the correct authentication and authorization mechanisms. This prevents unauthorized users from accessing and modifying the data. In PHP, we can use session to track the user's login status. The following is a simple sample code:

// login.php

// 验证用户提交的用户名和密码
$username = $_POST['username'];
$password = $_POST['password'];

// 在数据库中验证用户名和密码

// 如果验证成功，设置session
$_SESSION['user'] = $username;

// 跳转到登录成功页面
header('Location: dashboard.php');
exit;

In Vue.js, we can use its routing and navigation guard functions to implement page-level access control. The following is a simple sample code:

// router.js

import Vue from 'vue';
import Router from 'vue-router';

Vue.use(Router);

const router = new Router({
  // 路由配置
});

router.beforeEach((to, from, next) => {
  // 判断用户是否登录，如果未登录跳转到登录页
  const loggedIn = // 判断用户是否已登录的代码
  if (!loggedIn && to.path !== '/login') {
    next('/login');
  } else {
    next();
  }
});

export default router;

2. Use HTTPS to encrypt transmission data

Using HTTPS protocol to encrypt transmission data is one of the important measures to prevent data leakage. In PHP, we can enable HTTPS in the configuration file. The following is a sample code:

// config.php

define('SECURE', true);

// 其他配置信息

In Vue.js, we can use the Axios library to initiate HTTPS requests. The following is a simple sample code:

// api.js

import axios from 'axios';

const instance = axios.create({
  // 其他配置信息
  https: true
});

export default instance;

3. Encrypt sensitive data

In addition to encryption when transmitting data, we can also encrypt stored sensitive data. In PHP, we can use the functions provided by the openssl library to implement symmetric and asymmetric encryption. The following is a sample code:

// encryption.php

// 对称加密
function encrypt($data, $key) {
  return openssl_encrypt($data, 'AES-128-ECB', $key);
}

// 对称解密
function decrypt($data, $key) {
  return openssl_decrypt($data, 'AES-128-ECB', $key);
}

// 非对称加密
function encryptKey($data, $publicKey) {
  openssl_public_encrypt($data, $encrypted, $publicKey);
  return base64_encode($encrypted);
}

// 非对称解密
function decryptKey($data, $privateKey) {
  $encrypted = base64_decode($data);
  openssl_private_decrypt($encrypted, $decrypted, $privateKey);
  return $decrypted;
}

In Vue.js, we can use the CryptoJS library to implement encryption and decryption functions. The following is a sample code:

// encryption.js

import CryptoJS from 'crypto-js';

// 对称加密
function encrypt(data, key) {
  return CryptoJS.AES.encrypt(data, key).toString();
}

// 对称解密
function decrypt(data, key) {
  const bytes = CryptoJS.AES.decrypt(data, key);
  return bytes.toString(CryptoJS.enc.Utf8);
}

// 非对称加密
function encryptKey(data, publicKey) {
  const encrypted = CryptoJS.RSA.encrypt(data, publicKey).toString();
  return btoa(encrypted);
}

// 非对称解密
function decryptKey(data, privateKey) {
  const decrypted = CryptoJS.RSA.decrypt(atob(data), privateKey).toString(CryptoJS.enc.Utf8);
  return decrypted;
}

Through the above best practices, we can use PHP and Vue.js to develop a more secure data management system. Reasonable authentication and authorization mechanisms, HTTPS encrypted transmission, and encryption of sensitive data can effectively prevent data leakage and modification and enhance system security. Hopefully the sample code provided in this article will help readers understand and implement these best practices.
