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. Swift

func chilkatTest() {
    var success: Bool = false

    let cert = CkoCert()!

    // If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
    cert.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.
    success = cert.load(fromSmartcard: "")
    if success == false {
        print("\(cert.lastErrorText!)")
        print("Certificate not loaded.")
        return
    }

    // 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.
    print("\(cert.lastErrorText!)")

    print("Found: \(cert.subjectDN!) serial=\(cert.serialNumber!)")
