Proxy Mate

A proxy server is a kind of "mediator" between your equipment and a remote server (or the whole Internet). It can be used, for example, to swap your real IP address for another one, to bypass blocking. Proxies can also be actively used to intercept traffic (e.g. when testing created web applications).

It depends on which browser you are using. In Opera, Chrome, Edge a proxy is configured at the level of the operating system itself. In Firefox in the settings there is a special item (in the "Privacy" section).

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 want to capture data logged to the console in JavaScript and save it to a JSON file, you can follow these steps:

Capture Data in JavaScript:
Log the data you want to capture using console.log in your JavaScript code.

// Example data to be logged
const dataToLog = { key1: 'value1', key2: 'value2', key3: 'value3' };

// Log the data to the console
console.log(dataToLog);

Redirect Console Output:
You can redirect the console output to a variable using console.log = function() { ... }. Create an array to store the logged messages.

// Example array to store console messages
let consoleMessages = [];

// Redirect console.log to store messages in the array
console.log = function() {
  consoleMessages.push(Array.from(arguments));
};

// Log the data to the console
console.log(dataToLog);

Write Data to JSON File:
Use the fs (File System) module in Node.js to write the captured data to a JSON file.

const fs = require('fs');

// Write the consoleMessages array to a JSON file
fs.writeFileSync('output.json', JSON.stringify(consoleMessages, null, 2));

Note: The code above assumes you are working in a Node.js environment. If you are in a browser environment, you might need to use other methods to write data to a file, such as using the Blob API and creating a download link.

const jsonData = JSON.stringify(consoleMessages, null, 2);
const blob = new Blob([jsonData], { type: 'application/json' });
const url = URL.createObjectURL(blob);

// Create a download link
const downloadLink = document.createElement('a');
downloadLink.href = url;
downloadLink.download = 'output.json';

// Append the link to the document and trigger the download
document.body.appendChild(downloadLink);
downloadLink.click();
document.body.removeChild(downloadLink);

A proxy server passes all traffic through itself, acting as an intermediary between the user and the remote server. It is most often used to conceal the real IP, to conditionally change the user's location, or to analyze traffic (for example, when testing web applications).
