KeyedHashAlgorithm.Key Property

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

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

Public Overridable Property Key As Byte()
Dim instance As KeyedHashAlgorithm 
Dim value As Byte()

value = instance.Key

instance.Key = value

Property Value

Type: System.Byte()
The key to use in the hash algorithm.


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.

Public Overrides Property Key() As Byte()
        Return CType(keyedCrypto.Key.Clone(), Byte())
    End Get 
    Set(ByVal Value As Byte())
        keyedCrypto.Key = CType(Value.Clone(), Byte())
    End Set 
End Property
