Proxy Scoper

In the "Settings" of any Android smartphone there is a "VPN" item. And there you can manually specify the parameters of the proxy, through which the connection to the Internet will be made. There, some of the programs also import ready-made scripts for proxy connections.

Parsing PDF files in C++ can be a complex task due to the intricacies of the PDF format. However, you can use third-party libraries to simplify the process. One popular library for PDF parsing in C++ is "Poppler."

Here are the basic steps to parse PDF files using the Poppler library:

1. Install Poppler:

   • On Linux: You can typically install Poppler using the package manager for your distribution (e.g., apt-get install poppler-utils on Ubuntu).
   • On Windows: You can download the Poppler binaries from the official Poppler release page or use package managers like MSYS2 or vcpkg.

2. Use Poppler in C++:

   • Here's a simple example using Poppler in C++ to extract text from a PDF file:

#include 
#include 

int main() {
    // Replace "your_file.pdf" with the path to your PDF file
    QString pdfFilePath = "your_file.pdf";

    // Open the PDF file
    Poppler::Document* document = Poppler::Document::load(pdfFilePath);

    if (document) {
        // Iterate through pages
        for (int i = 0; i < document->numPages(); ++i) {
            Poppler::Page* pdfPage = document->page(i);

            // Extract text from the page
            QString text = pdfPage->text();
            std::cout << text.toStdString() << std::endl;

            delete pdfPage;
        }

        delete document;
    } else {
        std::cerr << "Failed to open the PDF file." << std::endl;
    }

    return 0;
}

Build and Link:

• Make sure to link your C++ program with the Poppler library. For example, using g++ on Linux:

g++ your_program.cpp -o your_program -lpoppler-qt5

4. Run the Program:

   • Execute your compiled program and provide the path to the PDF file as a command-line argument.

Keep in mind that this is a simple example, and Poppler provides more functionalities for extracting various information from PDF files. You might need to adapt the code based on your specific requirements.

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.

To specify the data of a proxy server in the Opera browser, you need to follow the algorithm below:

Open the browser.
Click on the Opera icon in the upper left corner.
Go to "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the tab that opens, specify the IP address of the proxy server. The address must be entered in the field of the protocol to which the proxy server belongs. You can get this information from your proxy provider. Click "OK" to save your settings.

There are three types of proxies that work using three types of protocols. The weakest one is HTTP. It is long outdated and unsuitable for visiting web resources. HTTPS works through a secure protocol and is most often used for web surfing. SOCKS5 proxies are capable of working with the largest number of programs and protocols. They are also beneficial because they keep your IP address anonymous in the request header.
