HTTP proxies are used for surfing the Internet and working with social networks. However, when using this type of proxy, the user's IP address remains unprotected. At the same time, the connection speed remains high.
SOCKS proxy are designed to use programs and visit sites anonymously. Also this type of proxy allows bypassing the resources with proxy-server protection.
To sum up: SOCKS proxies are a more advanced development compared to HTTP. However, to use SOCKS, you must know how to configure your browser and use special utilities.
Each option has its own advantages and disadvantages. HTTP is faster because it supports caching. And SOCKS provides better anonymity because it hides the headers of requested pages.
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
You need to go to "Settings", click on "WiFi", select the current network to which the smartphone is connected, tap on "Proxy settings". And then - deactivate the item.
To check the quality of a proxy server, you can use one of the proxy checkers. There are a lot of them on the Internet. For example, hidemy.name. On the page of the checker you need to specify the IP-address and port of the required proxy server.
