Vue3 TS Vite development tips: how to encrypt and store data

With the rapid development of Internet technology, data security and privacy protection are becoming more and more important important. In the Vue3 TS Vite development environment, how to encrypt and store data is a problem that every developer needs to face. This article will introduce some common data encryption and storage techniques to help developers improve application security and user experience.

1. Data encryption

1. Front-end data encryption

Front-end encryption is an important part of protecting data security. Commonly used front-end encryption algorithms include AES, RSA, SHA, etc. In the Vue3 TS Vite development environment, you can use the crypto-js library for data encryption.

First, you need to install the crypto-js library:

npm install crypto-js

Then, you can introduce the crypto-js library where encryption is required:

import { AES } from 'crypto-js'

const encryptData = (data: string, key: string) => {
  const encryptedData = AES.encrypt(data, key).toString()
  return encryptedData
}

const decryptedData = (encryptedData: string, key: string) => {
  const decryptedData = AES.decrypt(encryptedData, key).toString(crypto.enc.Utf8)
  return decryptedData
}

In the above code, the encryptData function The data is encrypted using the AES algorithm, and the decryptedData function is used to decrypt the encrypted data. Among them, data is the data that needs to be encrypted, and key is the encryption key.

2. Back-end data encryption

In addition to front-end encryption, back-end encryption is also an important means to protect data security. For back-end development, some common encryption algorithms and related libraries can be used to encrypt sensitive data.

For example, in Node.js, you can use the crypto library for data encryption. The following is a simple example:

const crypto = require('crypto')

const encryptData = (data, key) => {
  const cipher = crypto.createCipher('aes-256-cbc', key)
  let encryptedData = cipher.update(data, 'utf8', 'hex')
  encryptedData += cipher.final('hex')
  return encryptedData
}

const decryptedData = (encryptedData, key) => {
  const decipher = crypto.createDecipher('aes-256-cbc', key)
  let decryptedData = decipher.update(encryptedData, 'hex', 'utf8')
  decryptedData += decipher.final('utf8')
  return decryptedData
}

In the above code, the encryptData function uses the AES-256-CBC algorithm to encrypt data, and the decryptedData function is used to decrypt the encrypted data. Among them, data is the data that needs to be encrypted, and key is the encryption key.

2. Data Storage

In the Vue3 TS Vite development environment, data storage usually includes two methods: local storage (LocalStorage) and remote storage (server database, etc.).

1. Local Storage

Local storage refers to saving data in the local storage space of the browser, and LocalStorage is commonly used. LocalStorage has high read and write speeds and large storage space, and is suitable for saving some small, insensitive data. The method of using LocalStorage is as follows:

// 存儲數(shù)據(jù)
localStorage.setItem('key', 'value')

// 讀取數(shù)據(jù)
const data = localStorage.getItem('key')

// 刪除數(shù)據(jù)
localStorage.removeItem('key')

It should be noted that since LocalStorage is saved in the browser, there is a risk of tampering by the user. Therefore, when storing sensitive data, you should consider using encryption algorithms to encrypt the data to improve data security.

2. Remote storage

Remote storage refers to saving data in the server's database. Commonly used ones include MySQL, MongoDB, etc. Remote storage can ensure long-term storage and security of data, and is suitable for storing sensitive and large-volume data.

When performing remote storage, the security of data transmission needs to be considered. Under normal circumstances, data can be transmitted through the HTTPS protocol to ensure data encryption and security during transmission.

3. Summary

This article introduces the techniques for data encryption and storage in the Vue3 TS Vite development environment. For data encryption, front-end encryption and back-end encryption can be used to protect data security. For data storage, you can choose between local storage and remote storage, and select and use them according to actual needs. By rationally selecting encryption algorithms and storage methods, we can effectively protect data security and improve the user experience of applications.

In general, data encryption and storage are issues that every developer needs to pay attention to. Only by ensuring data security and privacy protection can we build user trust and provide users with safer and more reliable application services. Therefore, during the development process, it is important to pay attention to the issues of data encryption and storage, and take corresponding measures to ensure data security and privacy protection.
