(AutoIt) SSL Server Example

Demonstrates how to create an SSL socket for accepting connections. This example is *very* simple in that it will create an SSL socket for accepting a single connection. It will read a message from the client, send a reply, and exit.

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

$oListenSslSocket = ObjCreate("Chilkat.Socket")

; An SSL server needs a digital certificate.  This example loads it from a PFX file.

; Create an instance of a certificate store object, load a PFX file,
; locate the certificate we need, and use it.
; (a PFX file may contain more than one certificate.)
$oCertStore = ObjCreate("Chilkat.CertStore")
; The 1st argument is the filename, the 2nd arg is the 
; PFX file's password:
Local $bSuccess = $oCertStore.LoadPfxFile("chilkat.pfx","test")
If ($bSuccess <> True) Then
    ConsoleWrite($oCertStore.LastErrorText & @CRLF)
    Exit
EndIf

; Find the certificate to be used for SSL:
Local $oCert
$oCert = $oCertStore.FindCertBySubject("Chilkat Software, Inc.")
If ($oCertStore.LastMethodSuccess = False) Then
    ConsoleWrite($oCertStore.LastErrorText & @CRLF)
    Exit
EndIf

; Use the certificate:
$bSuccess = $oListenSslSocket.InitSslServer($oCert)
If ($bSuccess <> True) Then

    ConsoleWrite($oListenSslSocket.LastErrorText & @CRLF)
    Exit
EndIf

; Bind and listen on a port:
Local $iMyPort = 8123
; Allow for a max of 5 queued connect requests.
Local $iBackLog = 5
$bSuccess = $oListenSslSocket.BindAndListen($iMyPort,$iBackLog)
If ($bSuccess <> True) Then
    ConsoleWrite($oListenSslSocket.LastErrorText & @CRLF)
    Exit
EndIf

; If accepting an SSL/TLS connection, the SSL handshake is part of the connection
; establishment process. This involves a few back-and-forth messages between the 
; client and server to establish algorithms and a shared key to create the secure 
; channel. The sending and receiving of these messages are governed by the 
; MaxReadIdleMs and MaxSendIdleMs properties. If these properties are set to 0 
; (and this is the default unless changed by your application), then the 
; AcceptNextConnection can hang indefinitely during the SSL handshake process. 
; Make sure these properties are set to appropriate values before calling AcceptNextConnection.

; Set a 10 second max for waiting to read/write.  This is for the SSL/TLS handshake establishment.
$oListenSslSocket.MaxReadIdleMs = 10000
$oListenSslSocket.MaxSendIdleMs = 10000

; Accept a single client connection and establish the secure SSL/TLS channel:
Local $oClientSock
Local $iMaxWaitMillisec = 20000
$oClientSock = $oListenSslSocket.AcceptNextConnection($iMaxWaitMillisec)
If ($oListenSslSocket.LastMethodSuccess = False) Then
    ConsoleWrite($oListenSslSocket.LastErrorText & @CRLF)
    Exit
EndIf

; The client (in this example) is going to send a "Hello Server! -EOM-" 
; message.  Read it:
Local $sReceivedMsg = $oClientSock.ReceiveUntilMatch("-EOM-")
If ($oClientSock.LastMethodSuccess <> True) Then
    ConsoleWrite($oClientSock.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite($sReceivedMsg & @CRLF)

; Send a "Hello Client! -EOM-" message:
$bSuccess = $oClientSock.SendString("Hello Client! -EOM-")
If ($bSuccess <> True) Then
    ConsoleWrite($oClientSock.LastErrorText & @CRLF)
    Exit
EndIf

; Close the connection with the client
; Wait a max of 20 seconds (20000 millsec)
$bSuccess = $oClientSock.Close(20000)
