SymmetricAlgorithm.KeySize Property

Definition

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

C#
public virtual int KeySize { get; set; }

Property Value

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

Exceptions

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).
