(.NET Core C#) Validate a Smartcard PIN
Validates a smartcard PIN. This example only runs on Windows and requires Chilkat v9.5.0.77 or greater.
// Note: Requires Chilkat v9.5.0.77 or greater.
Chilkat.Cert cert = new Chilkat.Cert();
cert.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.
bool success = cert.LoadFromSmartcard("");
if (success != true) {
Debug.WriteLine(cert.LastErrorText);
return;
}
// Check to see if the SmartCardPin property contains the valid PIN for the smartcard.
int pinValid = cert.CheckSmartCardPin();
if (pinValid < 0) {
Debug.WriteLine("Unable to check the PIN validity.");
Debug.WriteLine(cert.LastErrorText);
return;
}
if (pinValid == 1) {
Debug.WriteLine("PIN is valid.");
}
else {
Debug.WriteLine("PIN is invalid.");
}
