DES.Key Property

Gets or sets the secret key for the Data Encryption Standard (DES) algorithm.

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

public override byte[] Key { get; set; }
/** @property */
public byte[] get_Key ()

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

public override function get Key () : byte[]

public override function set Key (value : byte[])

Property Value

The secret key for the DES algorithm.

Exception typeCondition

ArgumentNullException

An attempt was made to set the key to a null reference (Nothing in Visual Basic).

ArgumentException

An attempt was made to set a key whose length is not equal to BlockSizeValue.

CryptographicException

An attempt was made to set a weak key (see IsWeakKey) or a semi-weak key (see IsSemiWeakKey).

If this property is a null reference (Nothing in Visual Basic) when it is used, GenerateKey is called to create a new random value.

The length of the key must be equal to BlockSizeValue.

This algorithm supports a key length of 64 bits.
