[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets or sets the secret key for the symmetric algorithm.

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

Syntax

'Declaration
Public Overridable Property Key As CryptoKey

public virtual CryptoKey Key { get; set; }

public:
virtual property CryptoKey^ Key {
    CryptoKey^ get ();
    void set (CryptoKey^ value);
}

abstract Key : CryptoKey with get, set
override Key : CryptoKey with get, set

function get Key () : CryptoKey
function set Key (value : CryptoKey)

Property Value

Type: System.Security.Cryptography. . :: . .CryptoKey
The secret key to use for the symmetric algorithm.

Remarks

The secret key is used both for encryption and for decryption. For a symmetric algorithm to be successful, the secret key must be known only to the sender and the receiver. The valid key sizes are specified by the particular symmetric algorithm implementation and are listed in the LegalKeySizes property.

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