(C#) Validate a Smartcard PINValidates 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(); // 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; } cert.SmartCardPin = "000000"; // 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."); } |
