(Lianja) Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers.

loCert = createobject("CkCert")

// If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
loCert.SmartCardPin = "12345678"

// To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
// When testing in this way, it's best to have only a single smartcard or token connected to the system.
llSuccess = loCert.LoadFromSmartcard("")
if (llSuccess = .F.) then
    ? loCert.LastErrorText
    ? "Certificate not loaded."
    release loCert
    return
endif

// The LastErrorText property on all Chilkat objects will contain 
// information even when the method call is successful.
// You can examine the LastErrorText to see what Chilkat found and
// what decisions were made.
// 
// For example, if a certificate was successfully loaded via LoadFromSmartcard,
// but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
// then we would want to examine the LastErrorText from the call to
// LoadFromSmartcard to get detailed information about the card.
? loCert.LastErrorText

? "Found: " + loCert.SubjectDN + " serial=" + loCert.SerialNumber


release loCert
