DES.Key Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

DES.cs

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

public:
 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

Byte[]

The secret key for the DES algorithm.

Exceptions

ArgumentNullException

An attempt was made to set the key to null.

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(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.
