Vue Request Encrypted Signature

Vue is a very popular JavaScript framework that makes developing front-end applications easier and more efficient. As web applications become more complex, data security issues become more important. Therefore, it is particularly important to use cryptographic signatures in front-end programs. This article will introduce the process of cryptographically signing requests using the Vue framework.

1. What is an encrypted signature?

An encrypted signature refers to generating a piece of binary data on the request data based on a certain algorithm. This piece of binary data is called a signature and can be used to verify the source of the request and the integrity of the data. By comparing signatures, we can determine whether the data sent by the front end has been tampered with or forged.

2. Why encrypted signatures are needed

Data security is one of the important factors in maintaining user security on the Internet. HTTP is a stateless protocol, and no state information is saved between the client and server for each request. Therefore, request data that is not cryptographically signed can easily be intercepted and tampered by attackers. The cryptographic signature plays a role in ensuring the security and integrity of data transmission.

3. The implementation process of encrypted signature in Vue

The implementation of encrypted signature in Vue can be divided into the following steps:

1. Obtain the request data and request secret key.

2. Encrypt the request data according to a certain algorithm and key and generate a signature.

3. Attach a signature to the request data to verify the source and integrity of the request.

Let’s implement this process step by step:

3.1 Obtain request data and request key

We first define a request object, including the requested URL and HTTP method , request header information and request body data:

let request = {

url: 'https://api.example.com',
method: 'POST',
headers: {},
data: {
    name: 'test',
    age: 18
}

};

Next, we need to obtain the request key. The request key can be generated on the server or the client, as long as the client and server use the same key.

3.2 Encrypt the request data to generate a signature

In the Vue component, we use Axios to send the request. Axios is a popular HTTP client framework that can be used with Vue and Node.js. Here, we assume that we have successfully sent the request using Axios:

axios(request)
.then(res => console.log(res.data))
.catch(error => console.log(error));

Before sending the request, we need to encrypt the request data to generate a signature. We use the CryptoJS library to implement cryptographic signatures. CryptoJS is a JavaScript library used to implement various encryption algorithms, supporting encryption, decryption and hashing of data.

We first need to introduce the encryption algorithm and key to be used:

import CryptoJS from "crypto-js";

const algorithm = CryptoJS.algo.HMAC;
const secret = "abcdefg123456";

Then, we need to do the following processing:

1. Format the request data into a JSON string:

const body = JSON.stringify(request.data);

2. Remove spaces and newlines in strings:

const normalizedBody = body.replace(/s /g, '');

3. Concatenate the request method, request URL, request body data and timestamp (optional) in a specific format:

const message = [

  request.method.toUpperCase(),
  request.url,
  normalizedBody,
  timestamp
].join('

');

4. Use the HMAC algorithm to sign the message using the key.

const hmac = CryptoJS.HmacSHA256(message, secret);

As you can see, we use the HMAC-SHA256 algorithm, which has the advantages of fast speed, high security and compatibility Good sex. Among them, HMAC is a key-related hash function used for message authentication, using a key and a message to generate a message digest.

Finally, we can add the signature to the request headers with the following code:

request.headers = {

  'X-Timestamp': timestamp,
  Authorization: `Bearer ${hmac}`

}

3.3 Send with Signed request

Finally, we need to append the signature to the request data and send the request:

axios(request)
.then(res => console.log(res. data))
.catch(error => console.log(error));

4. Summary

Encrypted signature ensures the security and integrity of the requested data transmission important means. This article explains how to use the CryptoJS library to cryptographically sign request data in a Vue application. Specifically, we achieve the security and integrity of the request by obtaining the request data and key, encrypting the signature of the request data, and finally adding the signature to the request header.

In short, cryptographic signatures are a powerful tool that can improve the security of data transmission in applications and must be taken seriously.
