X509Certificate::GetKeyAlgorithmParameters Method

Returns the key algorithm parameters for the X.509v3 certificate as an array of bytes.

Namespace:  System.Security.Cryptography.X509Certificates
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual array<unsigned char>^ GetKeyAlgorithmParameters()

Return Value

Type: array<System::Byte>
The key algorithm parameters for the X.509 certificate as an array of bytes.

ExceptionCondition
CryptographicException

The certificate context is invalid.

The following example uses the GetKeyAlgorithmParameters method to return a certificate's key algorithm parameters as an array of bytes and displays it to the console.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int main()
{

   // The path to the certificate.
   String^ Certificate = "Certificate.cer";

   // Load the certificate into an X509Certificate object.
   X509Certificate^ cert = X509Certificate::CreateFromCertFile( Certificate );

   // Get the value. 
   array<Byte>^results = cert->GetKeyAlgorithmParameters();

   // Display the value to the console.
   System::Collections::IEnumerator^ enum0 = results->GetEnumerator();
   while ( enum0->MoveNext() )
   {
      Byte b = safe_cast<Byte>(enum0->Current);
      Console::Write( b );
   }
}
