Proxy Coding

The first thing to do is to go into the "Settings" of the messenger. In the "Data and Memory" section, at the very bottom, are the "Proxy Settings". Activate "Use proxy" and select the protocol SOCKS5, then in the line "Server" write the address and in the line "Port" - the port of the proxy. Since SOCKS5 often uses a system of authentication, you'll need to enter your username and password in the appropriate lines. Sign the result by clicking the checkbox at the top right corner of the screen. When you have connected the proxy to Telegram, don't forget to click "Share" and select the desired contacts.

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.

Building a chain of proxies in Selenium involves configuring a WebDriver with a Proxy object that represents a chain of proxies. Here's an example using Python with Selenium and the Chrome WebDriver:

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

# Create a Proxy object for the first proxy in the chain
proxy1 = Proxy()
proxy1.http_proxy = "http://proxy1.example.com:8080"
proxy1.ssl_proxy = "http://proxy1.example.com:8080"
proxy1.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the second proxy in the chain
proxy2 = Proxy()
proxy2.http_proxy = "http://proxy2.example.com:8080"
proxy2.ssl_proxy = "http://proxy2.example.com:8080"
proxy2.proxy_type = ProxyType.MANUAL

# Create a Proxy object for the final proxy in the chain
proxy3 = Proxy()
proxy3.http_proxy = "http://proxy3.example.com:8080"
proxy3.ssl_proxy = "http://proxy3.example.com:8080"
proxy3.proxy_type = ProxyType.MANUAL

# Create a chain of proxies
proxies_chain = f"{proxy1.proxy, proxy2.proxy, proxy3.proxy}"

# Set up ChromeOptions with the proxy chain
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f"--proxy-server={proxies_chain}")

# Create the WebDriver with ChromeOptions
driver = webdriver.Chrome(options=chrome_options)

# Now you can use the driver with the proxy chain for your automation tasks
driver.get("https://example.com")

# Close the browser window when done
driver.quit()

In this example:

Three Proxy objects (proxy1, proxy2, and proxy3) are created, each representing a different proxy in the chain. You need to replace the placeholder URLs (http://proxy1.example.com:8080, etc.) with the actual proxy server URLs.

The ProxyType.MANUAL option is used to indicate that the proxy settings are configured manually.

The proxies_chain variable is a comma-separated string representing the chain of proxies.

The --proxy-server option is added to ChromeOptions to specify the proxy chain.

A Chrome WebDriver instance is created with the configured ChromeOptions.

There are several ways to obtain a free proxy, but it's important to note that free proxies can be unreliable, slow, or even malicious. They may not provide the same level of security and privacy as paid proxies, and their performance can be unpredictable. However, if you still want to try a free proxy, here are some methods:

1. Online proxy lists: You can find lists of free proxies on various websites and forums. However, be cautious when using these proxies, as they may not be secure or reliable. Some popular websites for proxy lists include proxy-list.org and free-proxy-list.net.

2. Web proxy websites: Web proxy websites allow you to enter a URL, and the site will load the content for you using its proxy server. This can be useful for bypassing restrictions or maintaining privacy, but keep in mind that web proxies are generally slower and less secure than using a proxy on your device. Some popular web proxy websites include proxy-sites.com and hidester.com.

3. Use a free VPN service: While not a proxy, using a free VPN service can provide similar benefits, such as hiding your IP address, bypassing geographical restrictions, and improving security. Keep in mind that free VPN services may have limitations, such as data usage caps, slower speeds, or intrusive ads. Some popular free VPN services include ProtonVPN, Windscribe, and TunnelBear.

To connect your router to a proxy server, follow these steps:

1. Access router admin interface (usually 192.168.1.1)
2. Log in with default or custom credentials
3. Navigate to LAN/Network settings
4. Find and open Proxy Server settings
5. Enter proxy server type, IP, port, and authentication if needed
6. Save and apply changes
7. Update device proxy settings to use router's proxy server
