Ubuntu Docker Proxy

Before you change your proxy server, you should decide what kind of proxy you would like to install. There are a lot of choices, depending on your needs. Every buyer, when buying a proxy server, is given all the necessary information with the data for access - username and password, port, IP address. Without these data, you can't install and configure the proxy.

Every proxy server is of the type 168.1.1.1:8080, where the first part before the colon is the IP address of the remote computer through which the connection is made. The second part (after the colon, in this case 8080) is the port number through which your equipment will connect to that very remote server.

There are several options for its use: bypassing the blocking of websites, shopping in foreign online stores at regional (local) prices, access to a full library of media content, hiding your real IP-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.

Select the "Proxy" tab in the "Network" window, then click on Win+C and find the "Settings" item. In the window that opens, stop at "Change computer settings" and go to "Network". Select the "Proxy" line here and disable the proxy functionality.
