DES.Key Property

Definition

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

public override byte[] Key { get; set; }

Property Value

Byte[]

The secret key for the DES algorithm.

Exceptions

An attempt was made to set the key to null.

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

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

Remarks

If this property is null 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.
