AutoIt Requires Chilkat v11.0.0+

Accept TLS Connection with Client Authentication

See more Socket/SSL/TLS Examples

Demonstrates how to accept a TLS connection requiring client authentication. This is the case where the TLS client sends a certificate. It is also known as "Two-Way SSL". AutoIt

Local $bSuccess = False

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

$oListenSslSocket = ObjCreate("Chilkat.Socket")

;  An SSL/TLS server needs a digital certificate.  This example loads it from a PFX file.
;  Note: This is the server's certificate.

$oCert = ObjCreate("Chilkat.Cert")
;  The 1st argument is the file path, the 2nd arg is the 
;  PFX file's password:
$bSuccess = $oCert.LoadPfxFile("chilkat.pfx","test")
If ($bSuccess = False) Then
    ConsoleWrite($oCert.LastErrorText & @CRLF)
    Exit
EndIf

;  To accept client client certificates in the TLS handshake,
;  we must indicate a list of acceptable client certificate root CA DN's
;  that are allowed.  (DN is an acronym for Distinguished Name.)
;  Call AddSslAcceptableClientCaDn once for each acceptable CA DN.
;  Here are a few examples so you can see the general format of a DN.
$oListenSslSocket.AddSslAcceptableClientCaDn("C=SE, O=AddTrust AB, OU=AddTrust External TTP Network, CN=AddTrust External CA Root")
$oListenSslSocket.AddSslAcceptableClientCaDn("O=Digital Signature Trust Co., CN=DST Root CA X3")

;  Use the certificate:
$bSuccess = $oListenSslSocket.InitSslServer($oCert)
If ($bSuccess = False) Then
    ConsoleWrite($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 = False) 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 
;  AcceptNext can hang indefinitely during the SSL handshake process. 
;  Make sure these properties are set to appropriate values before calling AcceptNext.

;  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 $iMaxWaitMillisec = 20000
$oClientSock = ObjCreate("Chilkat.Socket")
$bSuccess = $oListenSslSocket.AcceptNext($iMaxWaitMillisec,$oClientSock)
If ($bSuccess = 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 = False) Then
    ConsoleWrite($oClientSock.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite($sReceivedMsg & @CRLF)

;  Send a "Hello Client! -EOM-" message:
$bSuccess = $oClientSock.SendString("Hello Client! -EOM-")
If ($bSuccess = False) 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)
