PKCS11 Find all Public Keys

See more PKCS11 Examples

Demonstrates how to list all public keys on an HSM.

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

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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.

  final pkcs11 = CkPkcs11();

  // Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
  // (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
  pkcs11.sharedLibPath = 'C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll';

  // Establish a logged-on session. (We can typically skip the login by passing an empty PIN if only needing to list public keys)
  // Use your actual PIN here, or an empty string to skip login.
  final pin = '0000';
  final userType = 1;
  try {
    pkcs11.quickSession(userType, pin);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Note: To find public keys, we need a session, but it doesn't necessarily need to be logged-on.

    pkcs11.findAllKeys('public', json);
  } on ChilkatException catch (e) {
