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. Swift

func chilkatTest() {
    var success: Bool = false

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

    let socket = CkoSocket()!

    // 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.socksHostname = "www.mysocksproxyserver.com"
    socket.socksPort = 1080
    socket.socksUsername = "myProxyLogin"
    socket.socksPassword = "myProxyPassword"
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    socket.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.
    var hostname: String? = "192.168.1.108"
    var ssl: Bool = false
    var maxWaitMillisec: Int = 20000
    success = socket.connect(hostname: hostname, port: 5555, ssl: ssl, maxWaitMs: maxWaitMillisec)
    if success != true {
        print("\(socket.lastErrorText!)")
        return
    }

    // Set maximum timeouts for reading an writing (in millisec)
    socket.maxReadIdleMs = 10000
    socket.maxSendIdleMs = 10000

    // The server (in this example) is going to send a "Hello World!" 
    // message.  Read it:
    var receivedMsg: String? = socket.receiveString()
    if socket.lastMethodSuccess != true {
        print("\(socket.lastErrorText!)")
        return
    }

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

    print("\(receivedMsg!)")
