public void set_Key (byte[] value)

JScript

public function get Key () : byte[]

public function set Key (value : byte[])

Property Value

Exceptions

Exception type	Condition
CryptographicException	An attempt was made to change the Key property after hashing has begun.

Remarks

This property is the public accessor for the KeyValue field.

Example

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.

C++

public override byte[] Key
{
    get
    {
        return (byte[]) keyedCrypto.Key.Clone();
    }
    set
    {
        keyedCrypto.Key = (byte[]) value.Clone();
    }
}

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

/** @property 
 */
public void set_Key(ubyte value[])
{
    keyedCrypto.set_Key((ubyte[])(value.Clone()));
} //set_Key
