Configure a Socket for Server-Side TLS

See more Socket/SSL/TLS Examples

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

LOCAL lnSuccess
LOCAL loSocket
LOCAL lcPfxPassword
LOCAL loCert
LOCAL loConnectedSock

lnSuccess = 0

loSocket = CreateObject('Chilkat.Socket')

*  The file path is relative to the application's current working directory.  An absolute path
*  may also be used.  Supply the path appropriate to your own environment.
*  The PFX password should come from a secure source rather than being hard-coded.
lcPfxPassword = "myPfxPassword"
loCert = CreateObject('Chilkat.Cert')
lnSuccess = loCert.LoadPfxFile("qa_data/server.pfx",lcPfxPassword)
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

*  Configure this object for server-side TLS using the certificate.  The certificate must have
*  access to its corresponding private key.
lnSuccess = loSocket.InitSslServer(loCert)
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

*  Listen for connections.  Accepted connections will use TLS.
lnSuccess = loSocket.BindAndListen(5000,25)
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

loConnectedSock = CreateObject('Chilkat.Socket')
lnSuccess = loSocket.AcceptNext(20000,loConnectedSock)
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
    RELEASE loCert

    CANCEL
ENDIF
