ISA Proxy

Open the control panel of your computer, find and select the item "Network connection", and then click "Show network connections", "Local network connections" and "Properties". If there is a tick next to "Obtain an IP address automatically", then no dedicated proxy has been used. If you see numbers there, it will be your address.

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.

Bypassing CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is generally considered unethical and against the terms of service of most websites. CAPTCHAs are designed to ensure that interactions with a website are performed by humans rather than automated scripts. Attempting to bypass CAPTCHA measures without explicit permission is likely to violate the website's terms of service and may have legal consequences.

If you are facing challenges with CAPTCHAs while using Selenium, consider the following alternatives:

1. Use CAPTCHA Solving Services:

   • Some third-party services offer CAPTCHA solving solutions. These services may use human workers to solve CAPTCHAs for you. However, keep in mind that using such services may still violate the terms of service of the website.

2. Contact the Website Owner:

   • If you are legitimately using Selenium for testing purposes or any other sanctioned activity, consider reaching out to the website owner or administrator. They may provide you with a way to bypass CAPTCHAs for testing purposes.

3. Use Headless Browsing:

   • Some websites may implement CAPTCHAs only for users interacting with the website in a visible browser window. Running Selenium in headless mode (without a visible browser) may reduce the likelihood of encountering CAPTCHAs.

4. Automate Only What's Necessary:

   • Avoid unnecessary interactions with the website and automate only what is essential. Excessive and rapid interactions may trigger CAPTCHAs.

5. Consider Alternatives:

   • Explore alternatives to web scraping if CAPTCHAs are a significant obstacle. Some websites provide APIs or other methods for accessing data without the need for traditional web scraping.

Always respect the terms of service of the websites you are interacting with and seek permission if you encounter obstacles like CAPTCHAs. Attempting to bypass security measures without authorization is not only unethical but may also lead to legal consequences.

To configure a Socks5 proxy for Chrome in Selenium using Python, you can use the --proxy-server command-line option with the Socks5 proxy address. Here's an example using the webdriver.Chrome class in Python:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService

# Socks5 proxy configuration
socks5_proxy = "socks5://127.0.0.1:1080"  # Replace with your actual Socks5 proxy address

# Configure Chrome options with proxy settings
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'--proxy-server={socks5_proxy}')

# Create a Chrome WebDriver instance with the configured options
chrome_service = ChromeService(executable_path="path/to/chromedriver")  # Replace with the actual path
driver = webdriver.Chrome(service=chrome_service, options=chrome_options)

# Example: Navigate to a website using the configured proxy
driver.get("https://www.example.com")

# Perform other actions with the WebDriver as needed

# Close the browser window
driver.quit()

- Replace "socks5://127.0.0.1:1080" with the actual Socks5 proxy address you want to use.
- Download the ChromeDriver executable from the official ChromeDriver download page and provide the path to the executable in the executable_path parameter of ChromeService.
- Update the driver.get() method to navigate to the website you want.

Make sure to have the selenium library installed (pip install selenium) and ensure that the ChromeDriver version is compatible with the Chrome browser installed on your system.

To address the "ERROR conda.core.link:_execute(637)" issue when installing Scrapy (Python 3.7) on Windows 8:

- Update conda: conda update conda
- Create a new virtual environment: conda create -n myenv python=3.7 and then conda activate myenv
- Install Scrapy using conda: conda install scrapy
- Check Python version compatibility with Scrapy.
- Alternatively, try installing Scrapy using pip: pip install scrapy
- Update Anaconda: conda update anaconda
- Temporarily disable antivirus/firewall.
- Verify network connection stability.
- If issues persist, seek assistance from community forums or provide more details for further help.
