CngKeyCreationParameters Class
Contains advanced properties for key creation.
Namespace: System.Security.Cryptography
Assembly: System.Core (in System.Core.dll)
The CngKeyCreationParameters type exposes the following members.
| Name | Description | |
|---|---|---|
 | CngKeyCreationParameters | Initializes a new instance of the CngKeyCreationParameters class. |
| Name | Description | |
|---|---|---|
| ExportPolicy | Gets or sets the key export policy. |
| KeyCreationOptions | Gets or sets the key creation options. |
| KeyUsage | Gets or sets the cryptographic operations that apply to the current key. |
| Parameters | Enables a CngKey object to be created with additional properties that are set before the key is finalized. |
| ParentWindowHandle | Gets or sets the window handle that should be used as the parent window for dialog boxes that are created by Cryptography Next Generation (CNG) classes. |
| Provider | Gets or sets the key storage provider (KSP) to create a key in. |
| UIPolicy | Gets or sets information about the user interface to display when a key is created or accessed. |
| Name | Description | |
|---|---|---|
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
CngKey objects contain properties. Some properties must be added to a key when it is created. Other properties can be added after the key is created.
The CngKeyCreationParameters class enables you to add properties to a key as it is being created. You can do this by passing a CngKeyCreationParameters object that contains standard key properties, such as key storage provider (KSP), export policy, key usage, user interface (UI) policy, and parent window handle, to the Create method. The CngKey object that is being created will be initialized with these values before it is finalized.
You can also add non-standard properties to a key by using the Parameters property.
If you need to add properties after a key is created, use the SetProperty method.
