KeyedHashAlgorithm::Key Property

Gets or sets the key to use in the hash algorithm.

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

public:
virtual property array<unsigned char>^ Key {
	array<unsigned char>^ get ();
	void set (array<unsigned char>^ value);
}

Property Value

Type: array<System::Byte>
The key to use in the hash algorithm.

ExceptionCondition
CryptographicException

An attempt was made to change the Key property after hashing has begun.

This property is the public accessor for the KeyValue field.

The following code example demonstrates how to override the Key property to retrieve the key used in the current KeyedHashAlgorithm object. This code example is part of a larger example provided for the KeyedHashAlgorithm class.

   virtual array<Byte>^ get() override
   {
      return dynamic_cast<array<Byte>^>(keyedCrypto->Key->Clone());
   }

   virtual void set( array<Byte>^value ) override
   {
      keyedCrypto->Key = dynamic_cast<array<Byte>^>(value->Clone());
   }
}
