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. B4X

Dim success As Boolean = False

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

Dim socket As ChilkatSocket
socket.Initialize("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.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.
Dim hostname As String = "192.168.1.108"
Dim ssl As Boolean = False
Dim maxWaitMillisec As Int = 20000
success = socket.Connect(hostname, 5555, ssl, maxWaitMillisec)
If success <> True Then
    Log(socket.LastErrorText)
    Return
End If


'  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:
Dim receivedMsg As String = socket.ReceiveString
If socket.LastMethodSuccess <> True Then
    Log(socket.LastErrorText)
    Return
End If


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

Log(receivedMsg)
