SSL Client Certificate

Demonstrates how to connect to an SSL server using a client-side certificate, send a simple message, receive a simple response, and disconnect.

*  Create an instance of a certificate store object, load a PFX file,
*  locate the certificate we need, and use it for signing.
*  (a PFX file may contain more than one certificate.)
loCertStore = CreateObject('Chilkat.CertStore')
*  The 1st argument is the filename, the 2nd arg is the
*  PFX file's password:
lnSuccess = loCertStore.LoadPfxFile("chilkat_secret.pfx","secret")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loCertStore.LastErrorText)

loSocket.SetSslClientCert(loCert)

lnSsl = 1

lnMaxWaitMillisec = 20000

*  The SSL server hostname may be an IP address, a domain name,
*  or "localhost".  You'll need to change this:

lcSslServerHost = "123.123.88.88"

lnSslServerPort = 8123

*  Connect to the SSL server:
lnSuccess = loSocket.Connect(lcSslServerHost,lnSslServerPort,lnSsl,lnMaxWaitMillisec)
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSocket.LastErrorText)
    QUIT
ENDIF

*  Set maximum timeouts for reading an writing (in millisec)
loSocket.MaxReadIdleMs = 20000
loSocket.MaxSendIdleMs = 20000

*  Send a "Hello Server! -EOM-" message:
lnSuccess = loSocket.SendString("Hello Server! -EOM-")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSocket.LastErrorText)
    QUIT
ENDIF

*  The server (in this example) is going to send a "Hello Client! -EOM-"
*  message.  Read it:

lcReceivedMsg = loSocket.ReceiveUntilMatch("-EOM-")
IF (lcReceivedMsg = NULL ) THEN
    =MESSAGEBOX(loSocket.LastErrorText)
    QUIT
ENDIF

*  Close the connection with the server
*  Wait a max of 20 seconds (20000 millsec)
loSocket.Close(20000)
