Softhsm2，发生pkcs11interop错误。 对于UInt32，值太大或太小

Question

I have following code for softhsm2 test via pkcs11interop library

using Net.Pkcs11Interop.Common;
using Net.Pkcs11Interop.HighLevelAPI;
using Net.Pkcs11Interop.HighLevelAPI80;
using System;
using System.Collections.Generic;
namespace ExportTest
{
    public class Softhsmtest
    {
        public static Pkcs11InteropFactories Factories = new Pkcs11InteropFactories();
        public static void Test()
        {

            using (Pkcs11 pkcs11 = new Pkcs11(Factories, @"C:\SoftHSM2\lib\softhsm2.dll",AppType.MultiThreaded))
            {
                ISlot slot = pkcs11.GetSlotList(SlotsType.WithTokenPresent)[0];
                using (ISession session = slot.OpenSession(SessionType.ReadWrite))
                {
                    session.Login(CKU.CKU_USER, "1111");                    
                    session.Logout();
                }
            }
        }
    }
}

Error Stacktrace i am getting is

Answer 1

I see two problems there:

1. You're using the current development version of Pkcs11Interop (master branch) that contains several API breaking changes and will change a LOT before it becomes stable version.

2. You're directly referencing types from Net.Pkcs11Interop.HighLevelAPI80 namespace which are supposed to be used only on Unix systems.

The solution:

You should use the current stable version - Pkcs11Interop 4.1.0 - with the following code:

using Net.Pkcs11Interop.Common;
using Net.Pkcs11Interop.HighLevelAPI;

namespace ExportTest
{
    public class Softhsmtest
    {
        public static void Test()
        {
            using (Pkcs11 pkcs11 = new Pkcs11(@"C:\SoftHSM2\lib\softhsm2.dll", AppType.MultiThreaded))
            {
                Slot slot = pkcs11.GetSlotList(SlotsType.WithTokenPresent)[0];
                using (Session session = slot.OpenSession(SessionType.ReadWrite))
                {
                    session.Login(CKU.CKU_USER, "1111");
                    session.Logout();
                }
            }
        }
    }
}
