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 */
public byte[] get_Key ()

/** @property */
public void set_Key (byte[] value)

public function get Key () : byte[]

public function set Key (value : byte[])

Not applicable.

Property Value

The key to use in the hash algorithm.

Exception typeCondition


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

/** @property 
public ubyte[] get_Key()
    return (ubyte[])keyedCrypto.get_Key().Clone();
} //get_Key

/** @property 
public void set_Key(ubyte value[])
} //set_Key
