PKCS11 Change Normal User PIN from Non-Logged-In State

See more PKCS11 Examples

When SetPin is called from a non-logged-in state, then it is the Normal User PIN that is changed.

Note: Requires Chilkat v9.5.0.89 or greater.

bool success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

Chilkat.Pkcs11 pkcs11 = new Chilkat.Pkcs11();

// See PKCS11 Find Driver Library Path for information about how to find the 
// PKCS11 driver file (if not explicitly known) for the plugged-in token or smart card in reader.

success = pkcs11.Initialize();
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

// Pass -1 for the slotID to open a session on the first non-empty slot.
int slotID = -1;

// Open a session.
bool readWrite = true;
success = pkcs11.OpenSession(slotID,readWrite);
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;

// We haven't logged in, but we can set the Normal User's PIN directly by providing 
// the existing PIN, and the new PIN.

// Change the PIN from 1234 to 0000
success = pkcs11.SetPin("1234","0000");
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);

// When finished, close the session.
// It is important to close the session (memory leaks will occur if the session is not properly closed).
