ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card. Rust

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

// Chilkat recommends the following free tool for interactively examining the contents of your smart card
// through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

// Let's first look at our smart card before importing a private key.
// Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:

// (image:https://example-code.com/images/gemalto_idprime_md_t0.JPG/endImage)

// First let's load a private key into the Chilkat private key object.
// (Chilkat provides the ability to load private keys from many different sources and formats.
// this example loads from a PEM file.)
let priv_key = chilkat::PrivateKey::new();
if priv_key.load_pem_file("qa_data/rsa/rsaPrivKey_pkcs8.pem").is_err() {
    println!("{}", priv_key.last_error_text());
    return;
}

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

// First we need to acquire a context to the smart card in the reader where it is inserted.
// 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());

// To import a private key, we'll need to be PIN authenticated.
// For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
let pin_id = "user".to_string();
let retval = scmd.pin_authenticate(&pin_id, "0000");
if retval != 0 {
    println!("PIN Authentication failed.");
    let _ = scmd.delete_context();
    return;
}

// Let's import into the "key exchange" position in key container #7.
if scmd.import_key(7, "kex", &priv_key, "user").is_err() {
    println!("PIN Authentication failed.");
    let _ = scmd.delete_context();
    return;
}

let _ = scmd.delete_context();

println!("Success.");
