Pkcs11Exception:方法C_Initialize返回了2147483907

皮耶罗·阿尔贝托(Piero Alberto)

我有一个简单的方法可以通过Pkcs11Interop访问我的HSM。

这是功能:

static public byte[] findTargetKeySValue(String label, String type, string command)
{
    try
    {
        string pkcs11LibraryPath = @"C:\Program Files\SafeNet\Protect Toolkit 5\Protect Toolkit C SDK\bin\hsm\cryptoki.dll";
        Utility.Logger("cryptoki dll path " + pkcs11LibraryPath, command);
        using (Pkcs11 pkcs11 = new Pkcs11(pkcs11LibraryPath, Inter_Settings.AppType))
        {
            // Find first slot with token present
            Slot slot = Inter_Helpers.GetUsableSlot(pkcs11);
            // Open RW session
            using (Session session = slot.OpenSession(SessionType.ReadOnly))
            {
                // Login as normal user
                session.Login(CKU.CKU_USER, Inter_Settings.NormalUserPin);
                // Prepare attribute template that defines search criteria
                List<ObjectAttribute> objectAttributes = new List<ObjectAttribute>();
                objectAttributes.Add(new ObjectAttribute(CKA.CKA_CLASS, CKO.CKO_SECRET_KEY));
                if (type == "DES")
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_KEY_TYPE, CKK.CKK_DES));
                else if (type == "DES2")
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_KEY_TYPE, CKK.CKK_DES2));
                else if (type == "DES3")
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_KEY_TYPE, CKK.CKK_DES3));
                objectAttributes.Add(new ObjectAttribute(CKA.CKA_LABEL, label));//PROVAK

                List<ObjectHandle> foundObjects = session.FindAllObjects(objectAttributes);
                var key = foundObjects[0];
                byte[] plainKeyValue = null;
                List<ObjectAttribute> readAttrsSensitive = session.GetAttributeValue(key, new List<CKA>() { CKA.CKA_SENSITIVE });
                if (!readAttrsSensitive[0].GetValueAsBool())
                {
                    Utility.Logger("findTargetKeySValue chiave " + label + " non senstive", command);
                    List<ObjectAttribute> readAttrs = session.GetAttributeValue(key, new List<CKA>() { CKA.CKA_VALUE });
                    if (readAttrs[0].CannotBeRead)
                        throw new Exception("Key cannot be exported");
                    else
                        plainKeyValue = readAttrs[0].GetValueAsByteArray();
                    //Console.WriteLine(ByteArrayToAsciiHEX(plainKeyValue));
                    session.Logout();
                    return plainKeyValue;
                }
                else
                {
                    Utility.Logger("findTargetKeySValue chiave " + label + " senstive", command);
                    Console.WriteLine("wrap/unwrap");
                    objectAttributes = new List<ObjectAttribute>();
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_CLASS, CKO.CKO_SECRET_KEY));
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_KEY_TYPE, CKK.CKK_DES3));
                    objectAttributes.Add(new ObjectAttribute(CKA.CKA_LABEL, "WRAPPING_KEY")); //WRAPPING_KEY WRK
                    foundObjects = session.FindAllObjects(objectAttributes);

                    var wrappingKey = foundObjects[0];
                    Mechanism m = new Mechanism(CKM.CKM_DES3_ECB);

                    var wrapped = session.WrapKey(m, wrappingKey, key);
                    //Console.WriteLine("wrapped " + ByteArrayToAsciiHEX(wrapped));

                    //Console.WriteLine(ByteArrayToAsciiHEX(session.Decrypt(m, wrappingKey, wrapped)));
                    var k = session.Decrypt(m, wrappingKey, wrapped); 
                    session.Logout();
                    return k;

                }
            }
        }
    }
    catch (Exception e)
    {
        //Console.WriteLine(e.ToSafeString());
        Utility.Logger("findTargetKeySValue " + e.ToSafeString(), command);
        return null;
    }
}

当套接字服务器收到来自客户端的调用时,我在套接字服务器中调用了此方法。

为了测试它,我创建了一个带循环的小程序。在此循环中,它每秒钟发送大约3个请求到使用Pkcs11Interop的服务器。

让我们将此测试程序称为tester.exe。如果我运行tester.exe,一切似乎都还可以。但是,当第一个tester.exe运行时,我尝试执行另一个tester.exe实例,但出现错误

Net.Pkcs11Interop.Common.Pkcs11Exception:方法C_Initialize返回了2147483907

在此特定行代码中:

using (Pkcs11 pkcs11 = new Pkcs11(pkcs11LibraryPath, Inter_Settings.AppType))

为什么?哪有问题

更新:

AppType为

public static AppType AppType = AppType.MultiThreaded;

设置为:

static Inter_Settings()
{

    if (AppType == AppType.MultiThreaded)
    {
        InitArgs40 = new LLA40.CK_C_INITIALIZE_ARGS();
        InitArgs40.Flags = CKF.CKF_OS_LOCKING_OK;

        InitArgs41 = new LLA41.CK_C_INITIALIZE_ARGS();
        InitArgs41.Flags = CKF.CKF_OS_LOCKING_OK;

        InitArgs80 = new LLA80.CK_C_INITIALIZE_ARGS();
        InitArgs80.Flags = CKF.CKF_OS_LOCKING_OK;

        InitArgs81 = new LLA81.CK_C_INITIALIZE_ARGS();
        InitArgs81.Flags = CKF.CKF_OS_LOCKING_OK;
    }

    // Convert strings to byte arrays
    SecurityOfficerPinArray = ConvertUtils.Utf8StringToBytes(SecurityOfficerPin);
    NormalUserPinArray = ConvertUtils.Utf8StringToBytes(NormalUserPin);
    ApplicationNameArray = ConvertUtils.Utf8StringToBytes(ApplicationName);

    // Build PKCS#11 URI that identifies private key usable in signature creation tests
    Pkcs11UriBuilder pkcs11UriBuilder = new Pkcs11UriBuilder();
    pkcs11UriBuilder.ModulePath = Pkcs11LibraryPath;
    pkcs11UriBuilder.Serial = TokenSerial;
    pkcs11UriBuilder.Token = TokenLabel;
    pkcs11UriBuilder.PinValue = NormalUserPin;
    pkcs11UriBuilder.Type = CKO.CKO_PRIVATE_KEY;
    pkcs11UriBuilder.Object = ApplicationName;

    PrivateKeyUri = pkcs11UriBuilder.ToString();
}

每次调用时,服务器实例都在上面的类中,并调用方法findTargetKeySValue。如果服务器接收到并发请求,则它将导致HSM交互失败...但是我发疯了,每次会话都不同,就像规范中所说的那样。

更新3

Thread t = new Thread(() => ih.findTargetKeySValue(label, type, command));
t.Start();
Thread tt = new Thread(() => ih.findTargetKeySValue(label, type, command));
tt.Start();
Thread ttt = new Thread(() => ih.findTargetKeySValue(label, type, command));
ttt.Start();
Thread tttt = new Thread(() => ih.findTargetKeySValue(label, type, command));
tttt.Start();
Thread ttttt = new Thread(() => ih.findTargetKeySValue(label, type, command));
ttttt.Start();

我创建了这个简单的代码片段来测试多线程(上面定义了findTargetKeySValue),它崩溃并显示消息“方法C_Initialize返回了2147483907”。此代码由供应商定义,并且为CKR_CRYPTOKI_UNUSABLE我将在下一个测试中使用它。

您没有在多线程应用程序中正确使用PKCS#11 API。这是一个已知问题

简短的答案是您需要确保:

  • 您正在Pkcs11应用程序中使用类的单个实例(即在服务器启动期间加载,在服务器停止期间卸载)
  • 您正在Session为每个加密操作使用类的新实例

长答案是您需要阅读PKCS#11 v2.20规范的“第6章-概述”其中解释了PKCS#11 API的所有基本概念。在完成这个强制性阅读,你可以看一看Pkcs11Interop.PDF项目,可以在多线程环境中使用类的工作代码示例。Pkcs11RsaSignature

这是从示例4修复代码的方法:
