Pkcs11Interop 空槽列表

Question

我最近创建了一个控制台应用程序，它包含 Pkcs11Interop 库的上下文以及 HSM dll。它运行良好，但我需要将代码重写为 Windows 服务（我将其托管为 gRPC 服务，因为它是 .NET Core）。托管WS后，出现slot list on factories.Pkcs11LibraryFactory.LoadPkcs11Library(factories, libraryPath, AppType.MultiThreaded).GetSlotList(SlotsType.WithOrWithoutTokenPresent).Find(slot => slot.SlotId == slotId) returns 一个空的插槽列表，即使它在控制台应用程序中返回了 3 个元素的列表。

    public Pkcs11Signature(string libraryPath, ulong slotId)
    {
        Pkcs11InteropFactories factories = new Pkcs11InteropFactories();
        _pkcs11Library = factories.Pkcs11LibraryFactory.LoadPkcs11Library(factories, libraryPath, AppType.MultiThreaded);
        _slot = _pkcs11Library.GetSlotList(SlotsType.WithOrWithoutTokenPresent).Find(slot => slot.SlotId == slotId);
    }
    
    public Pkcs11Signature Select(string alias, string certLabel, string pin, bool login)
    {
        List<CKA> pkAttributeKeys = new List<CKA>();
        pkAttributeKeys.Add(CKA.CKA_KEY_TYPE);
        pkAttributeKeys.Add(CKA.CKA_LABEL);
        pkAttributeKeys.Add(CKA.CKA_ID);
        List<CKA> certAttributeKeys = new List<CKA>();
        certAttributeKeys.Add(CKA.CKA_VALUE);
        certAttributeKeys.Add(CKA.CKA_LABEL);

        //CloseSession();            

        _session = _slot.OpenSession(SessionType.ReadWrite);
        if (login)
            _session.Login(CKU.CKU_USER, pin);

        ObjectAttributeFactory objectAttributeFactory = new ObjectAttributeFactory();

        List<IObjectAttribute> attributes = new List<IObjectAttribute>();
        attributes.Add(objectAttributeFactory.Create(CKA.CKA_CLASS, CKO.CKO_PRIVATE_KEY));
        List<IObjectHandle> keys = _session.FindAllObjects(attributes);

        bool found = false;
        foreach (IObjectHandle key in keys)
        {
            List<IObjectAttribute> keyAttributes = _session.GetAttributeValue(key, pkAttributeKeys);

            ulong type = keyAttributes[0].GetValueAsUlong();
            string encryptionAlgorithm;
            switch (type)
            {
                case (ulong)CKK.CKK_RSA:
                    encryptionAlgorithm = "RSA";
                    break;
                case (ulong)CKK.CKK_DSA:
                    encryptionAlgorithm = "DSA";
                    break;
                case (ulong)CKK.CKK_ECDSA:
                    encryptionAlgorithm = "ECDSA";
                    break;
                default:
                    continue;
            }

            string thisAlias = keyAttributes[1].GetValueAsString();

            if (thisAlias == null || thisAlias.Length == 0)
                thisAlias = keyAttributes[2].GetValueAsString();
            if (alias != null && !alias.Equals(thisAlias))
                continue;

            attributes.Clear();
            attributes.Add(objectAttributeFactory.Create(CKA.CKA_CLASS, CKO.CKO_CERTIFICATE));
            attributes.Add(objectAttributeFactory.Create(CKA.CKA_CERTIFICATE_TYPE, CKC.CKC_X_509));

            if (certLabel == null && thisAlias != null && thisAlias.Length > 0)
                certLabel = thisAlias;
            if (certLabel != null)
                attributes.Add(objectAttributeFactory.Create(CKA.CKA_LABEL, certLabel));

            List<IObjectHandle> certificates =_session.FindAllObjects(attributes);

            if (certificates.Count != 1)
                continue;

            IObjectHandle certificate = certificates[0];
            List<IObjectAttribute> certificateAttributes =_session.GetAttributeValue(certificate, certAttributeKeys);
            X509Certificate x509Certificate =
                new X509Certificate(X509CertificateStructure.GetInstance(certificateAttributes[0].GetValueAsByteArray()));

            List<X509Certificate> x509Certificates = new List<X509Certificate>();
            x509Certificates.Add(x509Certificate);
            attributes.Clear();
            attributes.Add(objectAttributeFactory.Create(CKA.CKA_CLASS, CKO.CKO_CERTIFICATE));
            attributes.Add(objectAttributeFactory.Create(CKA.CKA_CERTIFICATE_TYPE, CKC.CKC_X_509));
            List<IObjectHandle> otherCertificates =_session.FindAllObjects(attributes);
            foreach (IObjectHandle otherCertificate in otherCertificates)
            {
                if (!certificate.ObjectId.Equals(otherCertificate.ObjectId))
                {
                    certificateAttributes =_session.GetAttributeValue(otherCertificate, certAttributeKeys);
                    X509Certificate otherX509Certificate =
                        new X509Certificate(X509CertificateStructure.GetInstance(certificateAttributes[0].GetValueAsByteArray()));
                    x509Certificates.Add(otherX509Certificate);
                }
            }

            found = true;
            _alias = thisAlias;
            _encryptionAlgorithm = encryptionAlgorithm;
            _privateKeyHandle = key;
            _chain = x509Certificates.ToArray();
            break;
        }

        if (!found)
        {
            Console.WriteLine("Havent found");
            _alias = null;
            _encryptionAlgorithm = null;
            _privateKeyHandle = null;
            _chain = null;
        }

        return this;
    }

正在执行库：

    using (var signature = new Pkcs11Signature(@"C:\Program Files (x86)\hsm\hsm.dll", 3).
        Select(null, "CERT LABEL", "PIN", true)
    {
        (...DO THE WORK HERE...)
    }

我已经看到了，但是将 Windows 服务的“登录身份”更改为“本地服务”没有任何效果：

Answer 1

Pkcs11Interop returns 通过调用非托管 PKCS#11 库的 C_GetSlotList 函数接收的插槽。因此，如果您获得 0 个插槽，则 C_GetSlotList 返回 0 个插槽。您需要与 PKCS#11 库的供应商讨论这种情况，他们可能知道为什么他们的库看不到任何插槽。
