Sssonic2 Proxy

It means a private proxy server used by several users. For example, one of them has bought a paid proxy and lets his friend use it for a fee. That is, he "shared" his proxy (shared means "common").

If you want to parse JSON data and display it in a TreeView in a Windows Forms application using C#, you can use the Newtonsoft.Json library for parsing JSON and the TreeView control for displaying the hierarchical structure. Below is an example demonstrating how to achieve this

Install Newtonsoft.Json

Use NuGet Package Manager Console to install the Newtonsoft.Json package:

Install-Package Newtonsoft.Json

• Create a Windows Forms Application:

  • Open Visual Studio and create a new Windows Forms Application project.

• Design the Form:

  • Drag and drop a TreeView control and a Button on the form.

• Write Code to Parse JSON and Populate TreeView:

using System;
using System.Windows.Forms;
using Newtonsoft.Json.Linq;

namespace JsonTreeViewExample
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        private void btnLoadJson_Click(object sender, EventArgs e)
        {
            // Replace with your JSON data or URL
            string jsonData = @"{
                ""name"": ""John"",
                ""age"": 30,
                ""address"": {
                    ""city"": ""New York"",
                    ""zip"": ""10001""
                },
                ""emails"": [
                    ""[email protected]"",
                    ""[email protected]""
                ]
            }";

            // Parse JSON data
            JObject jsonObject = JObject.Parse(jsonData);

            // Clear existing nodes in TreeView
            treeView.Nodes.Clear();

            // Populate TreeView
            PopulateTreeView(treeView.Nodes, jsonObject);
        }

        private void PopulateTreeView(TreeNodeCollection nodes, JToken token)
        {
            if (token is JValue)
            {
                // Display the value
                nodes.Add(token.ToString());
            }
            else if (token is JObject)
            {
                // Display object properties
                var obj = (JObject)token;
                foreach (var property in obj.Properties())
                {
                    TreeNode newNode = nodes.Add(property.Name);
                    PopulateTreeView(newNode.Nodes, property.Value);
                }
            }
            else if (token is JArray)
            {
                // Display array items
                var array = (JArray)token;
                for (int i = 0; i < array.Count; i++)
                {
                    TreeNode newNode = nodes.Add($"[{i}]");
                    PopulateTreeView(newNode.Nodes, array[i]);
                }
            }
        }
    }
}

4. • In this example, the btnLoadJson_Click event handler simulates loading JSON data. You should replace it with your method of loading JSON data (e.g., from a file, a web service, etc.).
   • The PopulateTreeView method recursively populates the TreeView with nodes representing the JSON structure.

5. Run the Application:

   • Build and run your application. Click the button to load the JSON data into the TreeView.

This example assumes a simple JSON structure. You may need to adjust the code based on the structure of your specific JSON data. The PopulateTreeView method handles objects, arrays, and values within the JSON data.

Bouncy Castle is a popular cryptography library in C#. If you want to parse and extract Certificate Signing Request (CSR) extensions using Bouncy Castle, you can follow these steps

Add Bouncy Castle Library

First, make sure you have the Bouncy Castle library added to your project. You can do this via NuGet Package Manager:

Install-Package BouncyCastle

Parse CSR:

Use Bouncy Castle to parse the CSR. The following code demonstrates how to parse a CSR from a PEM-encoded string:

using Org.BouncyCastle.Pkcs;
using Org.BouncyCastle.OpenSsl;
using Org.BouncyCastle.X509;
using System;
using System.IO;

class Program
{
    static void Main()
    {
        string csrString = File.ReadAllText("path/to/your/csr.pem");

        Pkcs10CertificationRequest csr = ParseCSR(csrString);

        // Now you can work with the parsed CSR
    }

    static Pkcs10CertificationRequest ParseCSR(string csrString)
    {
        PemReader pemReader = new PemReader(new StringReader(csrString));
        object pemObject = pemReader.ReadObject();

        if (pemObject is Pkcs10CertificationRequest csr)
        {
            return csr;
        }

        throw new InvalidOperationException("Invalid CSR format");
    }
}

Extract Extensions:

Once you have the CSR parsed, you can extract extensions using the GetAttributes method. Extensions in a CSR are typically stored in the Attributes property. Here's an example:

foreach (DerObjectIdentifier oid in csr.CertificationRequestInfo.Attributes.GetOids())
{
    Attribute attribute = csr.CertificationRequestInfo.Attributes[oid];

    // Work with the attribute, e.g., check if it's an extension
    if (oid.Equals(PkcsObjectIdentifiers.Pkcs9AtExtensionRequest))
    {
        X509Extensions extensions = X509Extensions.GetInstance(attribute.AttrValues[0]);

        // Now you can iterate over extensions and extract the information you need
        foreach (DerObjectIdentifier extOID in extensions.ExtensionOids)
        {
            X509Extension extension = extensions.GetExtension(extOID);
            // Process the extension
        }
    }
}

Modify the code according to your specific requirements and the structure of your CSR. The example assumes a basic structure, and you may need to adapt it based on your CSR format and the extensions you're interested in.

If you are experiencing TimeoutException errors when trying to run Selenium in headless mode in PyCharm, there are several potential causes and solutions. Here are some steps to troubleshoot and address the issue:

1. Increase Wait Time:

   • Headless mode may introduce additional latency, and elements might take longer to load. Increase the timeout for explicit waits to give the elements enough time to become available.

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

driver = webdriver.Chrome(options=options)

# Increase the timeout as needed
wait = WebDriverWait(driver, 20)

# Example wait for an element to be clickable
element = wait.until(EC.element_to_be_clickable((By.ID, 'your_locator')))

• Use Different Locator Strategies:

  • If one locator strategy is causing timeouts, try using a different one. For example, switch from By.ID to By.XPATH or vice versa.

• Verify Element Identification:

  • Confirm that the element locator used in your script is correct and uniquely identifies the intended element.

• Check for JavaScript Errors:

  • Open the browser console and check for any JavaScript errors that might be affecting the behavior of the page.

• Increase Browser Window Size:

  • Some websites may behave differently in headless mode based on the window size. Try setting a larger window size.

options.add_argument('--window-size=1920,1080')

• Update ChromeDriver:

  • Ensure that you are using the latest version of ChromeDriver that is compatible with your Chrome browser version.

• Use a Custom User Agent:

  • Some websites may behave differently based on the user agent. Try setting a custom user agent.

options.add_argument('--user-agent=Your_Custom_User_Agent')

• Check for Captchas or Additional Security Measures:

  • Some websites may use captchas or additional security measures that could cause delays. Ensure that your script is not encountering captchas.

• Browser Profile:

  • In some cases, the behavior of the browser may change when running in headless mode. Experiment with different browser profiles or use a clean profile.

• Network Issues:

  • Ensure that there are no network-related issues that might be causing delays in loading elements.

• Check Proxy Settings:

  • If you are using a proxy, ensure that the proxy settings are configured correctly for headless mode.

• Headless Mode Compatibility:

  • Some websites may have issues with headless mode due to user agent detection or other factors. Test your script on different websites to see if the issue persists.

To receive and display a video stream via UDP protocol on a C# server, you can use the UdpClient class from the System.Net.Sockets namespace. Here's a simple example of how to set up a UDP server that receives a video stream and displays it on a Windows Forms application:

1. Create a new Windows Forms Application project in Visual Studio.

2. Add a PictureBox control to the form.

3. Double-click on the PictureBox to create a new method named pictureBox1_Click.

4. Add the following code to the pictureBox1_Click method:

using System;
using System.Drawing;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Windows.Forms;

namespace UDP_Video_Stream
{
    public partial class Form1 : Form
    {
        private const int Port = 12345;
        private byte[] _buffer = new byte[1024 * 1024]; // 1MB buffer
        private UdpClient _udpClient;
        private Thread _receiveThread;

        public Form1()
        {
            InitializeComponent();
            InitializeUdpClient();
        }

        private void InitializeUdpClient()
        {
            _udpClient = new UdpClient(Port);
            _udpClient.EnableBroadcast = true;
            _receiveThread = new Thread(ReceiveVideoStream);
            _receiveThread.Start();
        }

        private void ReceiveVideoStream()
        {
            while (true)
            {
                try
                {
                    IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
                    int receivedBytes = _udpClient.Receive(ref remoteEndPoint);

                    byte[] frame = new byte[receivedBytes];
                    Array.Copy(_buffer, frame, receivedBytes);

                    // Process the received frame (decode, display, etc.)
                    ProcessFrame(frame);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
        }

        private void ProcessFrame(byte[] frame)
        {
            // This method should be implemented to process the received frame.
            // For example, you can decode the frame using a library like FFmpeg and display it on the PictureBox.
            // Note that this is a complex task and requires additional libraries and code.
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            // This method is called when the PictureBox is clicked.
            // You can add any additional logic here if needed.
        }
    }
}

This code sets up a UDP server that listens on port 12345 and receives video frames. The ProcessFrame method should be implemented to process the received frame, which may involve decoding the frame
