Encrypting a UDP connection with TLS is not directly possible, as TLS is designed to work with TCP connections. However, you can use Datagram TLS (DTLS) or Secure Reliable Datagram (SRD) to achieve a similar result. DTLS is an extension of TLS that works with UDP, while SRD is a protocol that provides secure and reliable datagrams over UDP.

Here's an example of how to encrypt a UDP connection with DTLS using the Crypto++ library in C++:

1. First, install the Crypto++ library on your system. You can find the installation instructions at: https://www.cryptopp.com/wiki/Installing

2. Create a new C++ project and include the necessary Crypto++ headers.

3. Define the necessary structures and classes for DTLS:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

4. Implement the DTLS handshake and data exchange:

int main()
{
    try
    {
        CryptoPP::AutoSeededRandomPool rng;

        // Generate a DTLS context
        CryptoPP::DTLS_Context dtlsContext(CryptoPP::DTLS_CLIENT);

        // Set up the DTLS context
        dtlsContext.SetPeerCertVerificationCallback(
            [](const CryptoPP::DTLS_PeerCertificate& peerCert, int& errorCode) -> bool
        {
            // Verify the peer certificate
            // Return true if the certificate is valid, false otherwise
        });

        // Perform the DTLS handshake
        dtlsContext.StartHandshake();

        // Send data over the encrypted UDP connection
        std::string data = "Hello, secure UDP!";
        std::vector encryptedData;
        dtlsContext.Encrypt(data.data(), data.size(), encryptedData);

        // Receive data over the encrypted UDP connection
        std::vector receivedData(encryptedData.size());
        dtlsContext.Decrypt(receivedData.data(), receivedData.size(), encryptedData);

        // Convert the received data to a string
        std::string receivedString(receivedData.begin(), receivedData.end());

        // Output the received data

To know the host of a proxy server, you can follow these steps:

Check the proxy settings: If you are using a proxy on your device or within an application, examine the proxy settings to see if the host (IP address or hostname) of the proxy server is mentioned.

Observe the proxy URL: The proxy URL can sometimes indicate the host of the proxy server. For example, an HTTP proxy URL usually starts with "http://" or "https://" followed by the proxy server's IP address or hostname, while a SOCKS proxy URL typically starts with "socks://" followed by the proxy server's IP address or hostname.

Consult the proxy provider: If you are unsure about the host of the proxy server you are using, you can always consult the proxy provider or the documentation that came with the proxy server. They should be able to provide you with the necessary information about the proxy server's host.

Use online tools or software: There are various online tools and software applications that can help you identify the host of a proxy. By connecting to the proxy server and analyzing the traffic, these tools can often determine the host of the proxy server.

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).

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).

The main scenarios for using a proxy server: bypassing blocking, hiding the real IP, protection of confidential data when connecting to public WiFi access points, interaction with blocked applications, connection to closed portals, forums (which operate only in one country, region).
