How to encrypt and decrypt data in Vue technology development

In Vue technology development, data encryption and decryption is an important security measure. By encrypting sensitive data, you can prevent data leakage and theft, and protect user privacy and information security. This article will introduce how to use common encryption algorithms for data encryption and decryption in Vue, and provide specific code examples.

1. Data encryption

1. Symmetric encryption algorithm
   The symmetric encryption algorithm uses the same key for encryption and decryption. Common symmetric encryption algorithms include DES, 3DES, AES, etc. The following is a sample code for data encryption using the AES algorithm:

// 安装crypto-js库：npm install crypto-js
import { AES, enc } from 'crypto-js'

// 加密函数
function encryptData(data, key) {
  const encrypted = AES.encrypt(data, key)
  return encrypted.toString()
}

// 使用示例
const data = 'Hello, world!'
const key = 'MySecretKey'
const encryptedData = encryptData(data, key)
console.log('加密后的数据：', encryptedData)

2. Asymmetric encryption algorithm
   The asymmetric encryption algorithm uses a pair of keys for encryption and decryption, one of which The key is public and is called the public key; the other key is private and can only be accessed by the holder and is called the private key. Common asymmetric encryption algorithms include RSA, DSA, etc. The following is a sample code for data encryption using the RSA algorithm:

// 安装crypto-js和node-rsa库：npm install crypto-js node-rsa
import NodeRSA from 'node-rsa'

// 生成密钥对
const rsa = new NodeRSA()
const publicKey = rsa.exportKey('public')
const privateKey = rsa.exportKey('private')

// 加密函数
function encryptData(data, publicKey) {
  const key = new NodeRSA(publicKey, 'public')
  const encrypted = key.encrypt(data, 'base64')
  return encrypted
}

// 使用示例
const data = 'Hello, world!'
const encryptedData = encryptData(data, publicKey)
console.log('加密后的数据：', encryptedData)

2. Data decryption

1. Symmetric decryption algorithm
   The symmetric decryption algorithm uses the same key to Perform encryption and decryption. The following is a sample code for data decryption using the AES algorithm:

// 安装crypto-js库：npm install crypto-js
import { AES, enc } from 'crypto-js'

// 解密函数
function decryptData(encryptedData, key) {
  const decrypted = AES.decrypt(encryptedData, key)
  return decrypted.toString(enc.Utf8)
}

// 使用示例
const encryptedData = 'aUUpkm20xwW2PiUCJyHRAklFMNntZcW7'
const key = 'MySecretKey'
const decryptedData = decryptData(encryptedData, key)
console.log('解密后的数据：', decryptedData)

2. Asymmetric decryption algorithm
   The asymmetric decryption algorithm uses a pair of keys for encryption and decryption, one of which The key is public and is called the public key; the other key is private and can only be accessed by the holder and is called the private key. The following is a sample code for data decryption using the RSA algorithm:

// 安装crypto-js和node-rsa库：npm install crypto-js node-rsa
import NodeRSA from 'node-rsa'

// 解密函数
function decryptData(encryptedData, privateKey) {
  const key = new NodeRSA(privateKey, 'private')
  const decrypted = key.decrypt(encryptedData, 'utf8')
  return decrypted
}

// 使用示例
const encryptedData = 'n89IKpAAjX6QJbejl3AxOR+yIZi6DW7'
const decryptedData = decryptData(encryptedData, privateKey)
console.log('解密后的数据：', decryptedData)

The above is a specific code example of how to encrypt and decrypt data in Vue technology development. Based on actual needs, you can choose an appropriate encryption algorithm and key length to ensure data security. In actual development, other security measures can also be combined, such as HTTPS, input verification, etc., to comprehensively improve the security of the system.
