How to implement data encryption and security protection in uniapp

Introduction: With the rapid development of the mobile Internet, data security issues have become increasingly important. When developing uniapp applications, how to protect user data security and prevent data leakage and tampering has become an urgent problem to be solved. This article will introduce how to implement data encryption and security protection in uniapp, and provide specific code examples.

1. Use HTTPS to protect data transmission

HTTPS is a secure transmission protocol that encrypts and protects network communications through the SSL/TLS protocol. In uniapp, you can enable HTTPS protected data transmission in the following ways:

1. Configure request in the network field in the manifest.json file Domain name, as shown below:

"network": {
  "request": {
    "domain": "https://api.example.com"
  }
}

2. Configure in the app-plus field in the manifest.json file sslVerify is false, enable HTTPS certificate verification, as shown below:

"app-plus": {
  "ios": {
    "sslVerify": false
  },
  "android": {
    "sslVerify": false
  }
}

2. Data encryption and decryption

In uniapp, you can use Encryption algorithms encrypt sensitive data to increase data security. Common encryption algorithms include MD5, AES, etc. The following uses the AES algorithm as an example to introduce how to encrypt and decrypt data in uniapp.

1. Install the crypto-js library

In the uniapp project, you can use the crypto-js library to encrypt and decrypt data. You can install the crypto-js library through npm and run the following command:

npm install crypto-js

2. Introduce the crypto-js library

Introduce crypto-js into the page that requires encryption and decryption Library, as shown below:

import CryptoJS from 'crypto-js'

3. Data Encryption

Use the AES algorithm to encrypt sensitive data, as shown below:

// 密钥
const key = CryptoJS.enc.Utf8.parse('1234567890123456')
// 偏移量
const iv = CryptoJS.enc.Utf8.parse('1234567890123456')
// 需要加密的数据
const data = '需要加密的数据'
// 加密后的数据
const encryptedData = CryptoJS.AES.encrypt(data, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }).toString()
console.log(encryptedData)

4. Data decryption

Use the AES algorithm to decrypt the encrypted data, as shown below:

// 密钥
const key = CryptoJS.enc.Utf8.parse('1234567890123456')
// 偏移量
const iv = CryptoJS.enc.Utf8.parse('1234567890123456')
// 需要解密的数据
const encryptedData = '加密后的数据'
// 解密后的数据
const decryptedData = CryptoJS.AES.decrypt(encryptedData, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }).toString(CryptoJS.enc.Utf8)
console.log(decryptedData)

3. Prevent data tampering

In addition to encrypting sensitive data, you also need to Verify data to prevent data from being tampered with. Common data verification methods include hash verification and digital signature verification.

1. Hash verification

In uniapp, you can use the hash algorithm to hash the data, obtain the hash value, and then compare it with the received hash The values ​​are compared to determine whether the data has been tampered with.

The following is a sample code for hash verification using the MD5 algorithm:

import CryptoJS from 'crypto-js'

// 数据
const data = '需要校验的数据'
// 哈希值
const hash = CryptoJS.MD5(data).toString()
console.log(hash)

2. Digital signature verification

Digital signature verification uses a non- Performed by symmetric encryption algorithm. To implement digital signature verification, a pair of public and private keys are required. The private key is used to sign the data, and the public key is then used to verify the signature.

In uniapp, you can use the RSA algorithm to implement digital signature verification. The following is the sample code:

import CryptoJS from 'crypto-js'
import { JSEncrypt } from 'jsencrypt'

// 生成密钥对
const encrypt = new JSEncrypt()
const publicKey = '公钥'
const privateKey = '私钥'
encrypt.setPublicKey(publicKey)
encrypt.setPrivateKey(privateKey)

// 数据
const data = '需要校验的数据'

// 使用私钥对数据进行签名
const signature = encrypt.sign(data, CryptoJS.SHA256, 'sha256')

// 使用公钥验证签名
const result = encrypt.verify(data, signature, CryptoJS.SHA256)
console.log(result)

Summary: It is very important to implement data encryption and security protection in uniapp. You can enable HTTPS by The protocol protects data transmission, uses encryption algorithms to encrypt and decrypt data, and uses hash verification and digital signature verification to prevent data from being tampered with. The above are specific code examples of implementation methods. I hope it will be helpful and inspiring to everyone.
