RSACryptoServiceProvider.UseMachineKeyStore 属性

定义

命名空间:

System.Security.Cryptography

程序集:

System.Security.Cryptography.dll

Source:

RSACryptoServiceProvider.Unix.cs

获取或设置一个值，该值指示是否应在计算机的密钥存储而不是用户配置文件存储中保留密钥。

public:
 static property bool UseMachineKeyStore { bool get(); void set(bool value); };

public static bool UseMachineKeyStore { get; set; }

static member UseMachineKeyStore : bool with get, set

Public Shared Property UseMachineKeyStore As Boolean

属性值

Boolean

如果应在计算机密钥存储中保留密钥，则为 true；否则为 false。

示例

下面的代码示例创建一个 RSACryptoServiceProvider 对象，并将静态 UseMachineKeyStore 属性设置为使用计算机密钥存储而不是用户配置文件密钥存储。

using namespace System::Security::Cryptography;

注解

将此属性设置为 true 等效于将 UseMachineKeyStore 标志传递给 CspParameters 对象。 属性 UseMachineKeyStore 适用于当前应用程序域中的所有代码，而 CspParameters 对象仅适用于显式引用它的类。 模拟或运行未加载用户配置文件的帐户时，这些设置非常有用。 仅当未使用参数进行初始化时RSACryptoServiceProvider，设置UseMachineKeyStore才会影响密钥存储位置。
