PKCS11 Find Private Key by Label

See more PKCS11 Examples

Demonstrates how to find a private key based on a user-specified label.

Note: This example requires Chilkat v9.5.0.96 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();

// Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
// For example:
pkcs11.set_shared_lib_path("C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll");

// Use your HSM's PIN.
let pin = "0000".to_string();

// Normal user = 1
let user_type = 1;

// Establish a logged-on user session with the HSM.
if pkcs11.quick_session(user_type, &pin).is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

// Provide a template to find a PKCS11 object.
let json_template = chilkat::JsonObject::new();

// Find an RSA private key with the label "MySshKey".
// Here's an example of how the key was originally imported: 
// PKCS11 Import SSH Key
let _ = json_template.update_string("class", "private_key");
let _ = json_template.update_string("key_type", "rsa");
let _ = json_template.update_string("label", "MySshKey");

let priv_key_handle = pkcs11.find_object(&json_template);
if priv_key_handle == 0 {
    println!("{}", pkcs11.last_error_text());
    return;
}

// The private key handle is only valid during the PKCS11 session.
// If you wish to use the private key in another PKCS11 session,
// you'll first need to find it.  See:  
println!("private key handle: {}", priv_key_handle);

// Do whatever you wish with the private key handle...
// ...
// ...

let _ = pkcs11.logout();
let _ = pkcs11.close_session();
