ECDiffieHellmanCng.KeySize Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Gets or sets the size, in bits, of the key modulus used by the asymmetric algorithm.

public:
 virtual property int KeySize { int get(); void set(int value); };

public override int KeySize { get; set; }

member this.KeySize : int with get, set

Public Overrides Property KeySize As Integer

Property Value

Int32

The size, in bits, of the key modulus used by the asymmetric algorithm.

Exceptions

CryptographicException

value is not permitted by LegalKeySizes.

Remarks

Setting this property to its current value has no visible effect. Setting this property to a new legal value discards the current key, but defers creation of a new key until one is needed.

Because key sizes do not uniquely identify elliptic curves, the use of the property setter is discouraged. To generate a new key on a specific curve, use the GenerateKey method.
