SslStream.IsSigned 属性

定义

命名空间:

System.Net.Security

程序集:

System.Net.Security.dll

Source:

SslStream.cs

获取一个 Boolean 值，该值指示使用此流发送的数据是否进行签名。

public:
 virtual property bool IsSigned { bool get(); };

public override bool IsSigned { get; }

member this.IsSigned : bool

Public Overrides ReadOnly Property IsSigned As Boolean

属性值

Boolean

如果在传输数据前对其签名，则为 true；否则为 false。

示例

下面的代码示例演示如何显示此属性的值。

static void DisplaySecurityServices( SslStream^ stream )
{
   Console::WriteLine( L"Is authenticated: {0} as server? {1}", stream->IsAuthenticated, stream->IsServer );
   Console::WriteLine( L"IsSigned: {0}", stream->IsSigned );
   Console::WriteLine( L"Is Encrypted: {0}", stream->IsEncrypted );
   Console::WriteLine( L"Is mutually authenticated: {0}", stream->IsMutuallyAuthenticated );
}

static void DisplaySecurityServices(SslStream stream)
{
   Console.WriteLine("Is authenticated: {0} as server? {1}", stream.IsAuthenticated, stream.IsServer);
   Console.WriteLine("IsSigned: {0}", stream.IsSigned);
   Console.WriteLine("Is Encrypted: {0}", stream.IsEncrypted);
   Console.WriteLine("Is mutually authenticated: {0}", stream.IsMutuallyAuthenticated);
}

Private Shared Sub DisplaySecurityServices(stream As SslStream)
    Console.WriteLine("Is authenticated: {0} as server? {1}", stream.IsAuthenticated, stream.IsServer)
    Console.WriteLine("IsSigned: {0}", stream.IsSigned)
    Console.WriteLine("Is Encrypted: {0}", stream.IsEncrypted)
    Console.WriteLine("Is mutually authenticated: {0}", stream.IsMutuallyAuthenticated)
End Sub

注解

数据签名有助于保护数据的完整性，即帮助接收方确定数据在传输过程中是否被篡改。
