Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets a value indicating whether a key pair is protected.
public:
property bool Protected { bool get(); };public bool Protected { get; }member this.Protected : boolPublic ReadOnly Property Protected As BooleanProperty Value
true if the key pair is protected; otherwise, false.
Exceptions
The key type is not supported.
The cryptographic service provider cannot be found.
-or-
The key container was not found.
Examples
The following code example creates a key container and retrieves information about that container.
using namespace System;
using namespace System::Security::Cryptography;
using namespace System::Text;
int main()

// a key container is not created until you call
// a method that uses the key. This example calls
// the Encrypt method before calling the
// CspKeyContainerInfo property so that a key
// container is created.
// Create some data to encrypt and display it.
String^ data = L"Here is some data to encrypt.";
Console::WriteLine( L"Data to encrypt: {0}", data );
// Convert the data to an array of bytes and
// encrypt it.
array<Byte>^byteData = Encoding::ASCII->GetBytes( data );
array<Byte>^encData = rsa->Encrypt( byteData, false );
// Display the encrypted value.
