PKCS11 Login / Logout

See more PKCS11 Examples

Sample code showing how to login and logout of a PKCS11 session. A session becomes authenticated when Login is called, and returns to the unauthenticated state when Logout is called. A smart card's PIN is passed to the Login method.

Note: This example requires Chilkat v9.5.0.88 or later.

Rust

// 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.

let pkcs11 = chilkat::Pkcs11::new();

// Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
// or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
pkcs11.set_shared_lib_path("aetpkss1.dll");

if pkcs11.initialize().is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

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

// Open a session.
let read_write = true;
if pkcs11.open_session(slot_id, read_write).is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

// Make it an authenticated session by calling Login.
// The smart card PIN is passed to the Login method.
// The user type can be one of three choices:
// 0 - Security Officer
// 1 - Normal User
// 2 - Context Specific.
// You'll likely always login as the Normal User.
let user_type = 1;
let pin = "0000".to_string();
if pkcs11.login(user_type, &pin).is_err() {
    println!("{}", pkcs11.last_error_text());
    let _ = pkcs11.close_session().is_ok();
    return;
}

// Do what is needed with the authenticated session...
// ...
// ...

// Revert to an unauthenticated session by calling Logout.
if pkcs11.logout().is_err() {
    println!("{}", pkcs11.last_error_text());
    let _ = pkcs11.close_session().is_ok();
    return;
}

// When finished, close the session.
// It is important to close the session (memory leaks will occur if the session is not properly closed).
if pkcs11.close_session().is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

println!("PKCS11 Login and Logout successfully demonstrated.");
