Set a TLS Client Certificate from a Cert Object

See more Socket/SSL/TLS Examples

Demonstrates Socket.SetSslClientCert, which configures a certificate as the client certificate for subsequent TLS connections. The certificate must have access to its private key.

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 lnBTls
LOCAL lnMaxWaitMs

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/client.pfx",lcPfxPassword)
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

*  Configure the client certificate before connecting.  Use this only when the server requests or
*  requires client-certificate authentication (mutual TLS).
lnSuccess = loSocket.SetSslClientCert(loCert)
IF (lnSuccess = 0) THEN
    ? loSocket.LastErrorText
    RELEASE loSocket
    RELEASE loCert
    CANCEL
ENDIF

lnBTls = 1
lnMaxWaitMs = 5000
