To decrypt Laravel cookies with React.js, you can follow these steps:

  1. First, make sure you have access to the Laravel application's encryption key as it is needed to decrypt the cookies. You can find the encryption key in the .env file of your Laravel application.
  2. In your React.js application, you can use the js-cookie library to access and decrypt the Laravel cookies. Install the library by running the following command:
1
npm install js-cookie


  1. Create a new file in your React.js application to store the decryption logic. For example, you can create a file named cookieService.js.
  2. In the cookieService.js file, import the js-cookie library and use it to decrypt the Laravel cookies. Here is an example implementation:

import Cookies from 'js-cookie';

const decryptCookie = (cookieName, encryptionKey) => {
  const encryptedValue = Cookies.get(cookieName);
  
  // Use the encryption key to decrypt the cookie value
  const decryptedValue = decrypt(encryptedValue, encryptionKey);
  
  return decryptedValue;
}

const decrypt = (encryptedValue, encryptionKey) => {
  // Use any decryption algorithm compatible with Laravel's encryption mechanism
}

export default decryptCookie;


  1. Use the decryptCookie function in your React components to decrypt the Laravel cookies. Remember to pass the cookie name and encryption key as parameters to the function.

import React from 'react';
import decryptCookie from './cookieService';

const MyComponent = () => {
  const decryptedValue = decryptCookie('laravel_cookie', 'encryption_key');
  
  return <div>{decryptedValue}</div>;
}

export default MyComponent;


By following these steps, you should be able to decrypt Laravel cookies in your React.js application using the provided encryption key. Remember to handle errors and edge cases accordingly to ensure a secure and robust implementation.
