Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

LOCAL loCert
LOCAL lnSuccess
LOCAL lnPinValid

* Note: Requires Chilkat v9.5.0.77 or greater.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Cert')
loCert = CreateObject('Chilkat.Cert')

loCert.SmartCardPin = "000000"

* Load the certificate on the smartcard currently in the reader (or on the USB token).
* Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
* See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
lnSuccess = loCert.LoadFromSmartcard("")
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loCert
    CANCEL
ENDIF

* Check to see if the SmartCardPin property contains the valid PIN for the smartcard.
lnPinValid = loCert.CheckSmartCardPin()
IF (lnPinValid < 0) THEN
    ? "Unable to check the PIN validity."
    ? loCert.LastErrorText
    RELEASE loCert
    CANCEL
ENDIF

IF (lnPinValid = 1) THEN
    ? "PIN is valid."
ELSE
    ? "PIN is invalid."
ENDIF

RELEASE loCert
