尝试创建密钥时;我被告知无法创建自己的键值，必须将它们生成/解包到 HSM 上。如果这不是真的，我已经附加了两个尝试/方法，以防我错过了什么。任何帮助将不胜感激！
环境：网络月神K6 5.1
图书馆：PKCS11Interop.Net
尝试 1：使用创建对象
错误：CKR_TEMPLATE_INCONSISTENT
string keyLabel = "CustomSecretKey"
byte[] Value = HexStringToByteArray(value);
privateKey = new List<ObjectAttribute>
{
//PKCS11V2.20 Common Attributes Defined @ 12.12.2
new ObjectAttribute(CKA.CKA_LABEL, keyLabel),
new ObjectAttribute(CKA.CKA_CLASS, CKO.CKO_SECRET_KEY),
new ObjectAttribute(CKA.CKA_KEY_TYPE, CKK.CKK_AES),
new ObjectAttribute(CKA.CKA_TOKEN, true),
new ObjectAttribute(CKA.CKA_ENCRYPT, true),
new ObjectAttribute(CKA.CKA_PRIVATE, true),
new ObjectAttribute(CKA.CKA_DECRYPT, true),
new ObjectAttribute(CKA.CKA_VALUE_LEN, 32),
new ObjectAttribute(CKA.CKA_VALUE, Value)
};
session.CreateObject(privateKey);
这显然不受支持？
尝试 2：使用解包密钥

我应该生成另一个密钥并使用它来解包吗？
显然，在与金雅拓交谈并发表一些评论后，无法在非保护服务器系列的网络 HSM 上执行此操作。该过程非常适合保护服务器 HSM(他们现在有一个保护服务器网络 HSM(。在更新我的解包过程以将 CBC 模式与 IV 一起使用后，我能够创建键，但不能使用指定的键值。
更新：在示例中添加了生成密钥对函数。
我能够使用以下代码将 AES 密钥"加载"到 HSM 中：
// Create factories used by Pkcs11Interop library
Pkcs11InteropFactories factories = new Pkcs11InteropFactories();
// Load unmanaged PKCS#11 library
using (IPkcs11Library pkcs11Library = factories.Pkcs11LibraryFactory.LoadPkcs11Library(factories, options.PKCS11LibraryPath, AppType.SingleThreaded))
{
// Find first slot with token present
ISlot slot = pkcs11Library.GetSlotList(SlotsType.WithTokenPresent)[0];
// Open RW session
using (ISession session = slot.OpenSession(SessionType.ReadWrite))
{
// Login as normal user
session.Login(CKU.CKU_USER, options.Pin);
// Generate asymmetric key encryption key pair
IObjectHandle asymKeyEncrpytionPublicKey = null;
IObjectHandle asymKeyEncryptionPrivateKey = null;
Helpers.GenerateKeyPair(session, out asymKeyEncrpytionPublicKey, out asymKeyEncryptionPrivateKey, "KEK");
// Load aes key from file
// Generate the key with the following command: "openssl rand -out aes256-forImport.key 32"
byte[] sourceKey = File.ReadAllBytes(options.aesKeyPath);
Console.WriteLine($"Loaded AES key: {BitConverter.ToString(sourceKey)}");
// Specify wrapping mechanism
IMechanism asymMechanism = session.Factories.MechanismFactory.Create(CKM.CKM_RSA_PKCS);
// Encrypt key in file
byte[] encryptedKey = session.Encrypt(asymMechanism, asymKeyEncrpytionPublicKey, sourceKey);

objectAttributes.Add(session.Factories.ObjectAttributeFactory.Create(CKA.CKA_CLASS, CKO.CKO_SECRET_KEY));
