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

Note: This example requires Chilkat v9.5.0.96 or later.

var 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.

var pkcs11 = new CkPkcs11();

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

// Use your HSM's PIN.
var pin = "0000";

// Normal user = 1
var userType = 1;

// Establish a logged-on user session with the HSM.
success = pkcs11.QuickSession(userType,pin);
if (success == false) {
    console.log(pkcs11.LastErrorText);
    return;
}

// Provide a template to find a PKCS11 object.
var jsonTemplate = new CkJsonObject();

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

var privKeyHandle = pkcs11.FindObject(jsonTemplate);
if (privKeyHandle == 0) {
    console.log(pkcs11.LastErrorText);
    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:  
console.log("private key handle: " + privKeyHandle);

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

pkcs11.Logout();
pkcs11.CloseSession();
