SymmetricAlgorithm.KeySize Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

SymmetricAlgorithm.cs

Gets or sets the size, in bits, of the secret key used by the symmetric algorithm.

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

public virtual int KeySize { get; set; }

member this.KeySize : int with get, set

Public Overridable Property KeySize As Integer

Property Value

Int32

The size, in bits, of the secret key used by the symmetric algorithm.

Exceptions

CryptographicException

The key size is not valid.

Remarks

The valid key sizes are specified by the particular symmetric algorithm implementation and are listed in the LegalKeySizes property.

Changing the KeySize value resets the key and generates a new random key. This happens whenever the KeySize property setter is invoked (including when it's assigned the same value).
