DES.Key Property


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

 virtual property cli::array <System::Byte> ^ Key { cli::array <System::Byte> ^ get(); void set(cli::array <System::Byte> ^ value); };
public override byte[] Key { get; set; }
member this.Key : byte[] with get, set
Public Overrides Property Key As Byte()

Property Value


The secret key for the DES algorithm.


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[])).


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.
