Kool Proxy

First you should check if its characteristics are correct. Some proxy servers are just IP address and port number, others use so called "connection script". You need to double-check that the data was entered correctly.

In Node.js, you can parse JSON using the built-in JSON object or the JSON.parse() method. Here's a simple example:

// JSON string
const jsonString = '{"name": "John", "age": 30, "city": "New York"}';

// Parse JSON using JSON.parse()
try {
  const jsonData = JSON.parse(jsonString);
  console.log('Parsed JSON:', jsonData);

  // Access individual properties
  console.log('Name:', jsonData.name);
  console.log('Age:', jsonData.age);
  console.log('City:', jsonData.city);
} catch (error) {
  console.error('Error parsing JSON:', error.message);
}

In this example:

• The jsonString contains a JSON-formatted string.
• JSON.parse() is used to parse the JSON string into a JavaScript object.
• The properties of the resulting object can be accessed just like any other JavaScript object.

If the JSON string is not valid, JSON.parse() will throw an error. To handle potential errors, it's a good practice to use a try...catch block.

If you have a JSON file and want to read and parse it in Node.js, you can use the fs (file system) module along with JSON.parse(). Here's an example:

const fs = require('fs');

// Read JSON file
fs.readFile('path/to/your/file.json', 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading file:', err.message);
    return;
  }

  // Parse JSON data
  try {
    const jsonData = JSON.parse(data);
    console.log('Parsed JSON from file:', jsonData);
  } catch (error) {
    console.error('Error parsing JSON:', error.message);
  }
});

Replace 'path/to/your/file.json' with the actual path to your JSON file.

Remember to handle errors appropriately, especially when dealing with file I/O operations or parsing potentially malformed JSON data.

Popup scraping typically involves interacting with web pages that have dynamic content, including popups or modals. To scrape data from popups, you may need to use a headless browser automation library. One popular choice is Selenium, which provides a WebDriver API for interacting with browsers.

Here's an example using Python and Selenium to scrape data from a webpage with a popup

Install Selenium:

pip install selenium

• Download WebDriver:

  • Download the WebDriver for the browser you want to use. In this example, I'll use ChromeDriver. Download it from ChromeDriver Downloads and place the executable in your project directory or in a directory listed in your system's PATH.

• Write the Scraping Code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def scrape_with_popup(url):
    # Set up the WebDriver (make sure the WebDriver executable is in the same directory or in your PATH)
    driver = webdriver.Chrome()

    try:
        # Open the webpage
        driver.get(url)

        # Locate and click the button/link that triggers the popup
        popup_trigger = driver.find_element(By.ID, 'popup-trigger')
        popup_trigger.click()

        # Wait for the popup to appear (adjust the timeout as needed)
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'popup-content')))

        # Extract data from the popup
        popup_content = driver.find_element(By.ID, 'popup-content').text
        print("Popup Content:", popup_content)

    finally:
        # Close the browser window
        driver.quit()

# Replace 'https://example.com' with the actual URL of the webpage
scrape_with_popup('https://example.com')

3. • Replace 'https://example.com' with the actual URL of the webpage you want to scrape.
   • Replace 'popup-trigger' and 'popup-content' with the actual IDs or other locators of the elements triggering the popup and the popup content.

4. Run the Code:

   • Execute the Python script, and it will open a browser, interact with the webpage, and print the content of the popup.

This example assumes that the webpage you are working with uses a trigger element (button/link) to open the popup.

Encrypting a UDP connection with TLS is not directly possible, as TLS is designed to work with TCP connections. However, you can use Datagram TLS (DTLS) or Secure Reliable Datagram (SRD) to achieve a similar result. DTLS is an extension of TLS that works with UDP, while SRD is a protocol that provides secure and reliable datagrams over UDP.

Here's an example of how to encrypt a UDP connection with DTLS using the Crypto++ library in C++:

1. First, install the Crypto++ library on your system. You can find the installation instructions at: https://www.cryptopp.com/wiki/Installing

2. Create a new C++ project and include the necessary Crypto++ headers.

3. Define the necessary structures and classes for DTLS:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

4. Implement the DTLS handshake and data exchange:

int main()
{
    try
    {
        CryptoPP::AutoSeededRandomPool rng;

        // Generate a DTLS context
        CryptoPP::DTLS_Context dtlsContext(CryptoPP::DTLS_CLIENT);

        // Set up the DTLS context
        dtlsContext.SetPeerCertVerificationCallback(
            [](const CryptoPP::DTLS_PeerCertificate& peerCert, int& errorCode) -> bool
        {
            // Verify the peer certificate
            // Return true if the certificate is valid, false otherwise
        });

        // Perform the DTLS handshake
        dtlsContext.StartHandshake();

        // Send data over the encrypted UDP connection
        std::string data = "Hello, secure UDP!";
        std::vector encryptedData;
        dtlsContext.Encrypt(data.data(), data.size(), encryptedData);

        // Receive data over the encrypted UDP connection
        std::vector receivedData(encryptedData.size());
        dtlsContext.Decrypt(receivedData.data(), receivedData.size(), encryptedData);

        // Convert the received data to a string
        std::string receivedString(receivedData.begin(), receivedData.end());

        // Output the received data

If you have the operating system Ubuntu, the messenger will not be able to connect to the proxy. On other operating systems, if this situation occurs, you should update your application to the latest version. Another reason for no connection may be a server restart. In this case, you should either wait for the traffic to decrease or connect to a new proxy. Sometimes, to get Telegram working via proxy again, you simply need to replace the outdated proxy server with a new one.
