ScMinidriver - Change Smart Card PIN (or USB token PIN)

See more ScMinidriver Examples

Demonstrates how to change the PIN for a smart card or USB token. Rust

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

let scmd = chilkat::ScMinidriver::new();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
let reader_name = "Alcor Micro USB Smart Card Reader 0".to_string();
if scmd.acquire_context(&reader_name).is_err() {
    println!("{}", scmd.last_error_text());
    return;
}

// If successful, the name of the currently inserted smart card is available:
println!("Card name: {}", scmd.card_name());

// Change the "user" PIN.  (Typically, you'll always be using the "user" PIN.)
let current_pin = "0000".to_string();
let new_pin = "1234".to_string();
let retval = scmd.pin_change("user", &current_pin, &new_pin);
if retval == -1 {
    println!("The PIN is already blocked.");
    return;
}

if retval == -2 {
    println!("The PinChange function failed for some unanticipated reason");
    println!("{}", scmd.last_error_text());
    return;
}

if retval == 0 {
    println!("PIN successfully changed.");
} else {
    println!("Current PIN is incorrect.");
    println!("Number of attempts remaining = {}", retval);
}

let _ = scmd.delete_context();
