SslStream.IsSigned 属性

定义

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。Gets a Boolean value that indicates whether the data sent using this stream is signed.

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 falsetrue if the data is signed before being transmitted; otherwise false.

示例

下面的代码示例演示如何显示此属性的值。The following code example demonstrates displaying the value of this property.

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 );
}


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);
}
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)
End Sub

注解

数据签名有助于保护数据的完整性,也就是说,它可帮助接收方确定数据在传输过程中是否已被篡改。Data signing helps to protect the integrity of the data, namely it helps the recipient determine whether the data has been tampered with while in transit.
