Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server. C++

#include <CkSocket.h>

void ChilkatSample(void)
    {
    bool success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkSocket socket;

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to calling Connect.  The connection may be SSL/TLS or 
    // non-secure - both will work with a SOCKS proxy.
    // The SOCKS hostname may be a domain name or 
    // IP address:
    socket.put_SocksHostname("www.mysocksproxyserver.com");
    socket.put_SocksPort(1080);
    socket.put_SocksUsername("myProxyLogin");
    socket.put_SocksPassword("myProxyPassword");
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    socket.put_SocksVersion(5);
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect to port 5555 of 192.168.1.108.
    // hostname may be a domain name or IP address.
    const char *hostname = "192.168.1.108";
    bool ssl = false;
    int maxWaitMillisec = 20000;
    success = socket.Connect(hostname,5555,ssl,maxWaitMillisec);
    if (success != true) {
        std::cout << socket.lastErrorText() << "\r\n";
        return;
    }

    // Set maximum timeouts for reading an writing (in millisec)
    socket.put_MaxReadIdleMs(10000);
    socket.put_MaxSendIdleMs(10000);

    // The server (in this example) is going to send a "Hello World!" 
    // message.  Read it:
    const char *receivedMsg = socket.receiveString();
    if (socket.get_LastMethodSuccess() != true) {
        std::cout << socket.lastErrorText() << "\r\n";
        return;
    }

    // Close the connection with the server
    // Wait a max of 20 seconds (20000 millsec)
    success = socket.Close(20000);

    std::cout << receivedMsg << "\r\n";
    }
