Property Value

Int32

The size, in bits, of the key.

Remarks

For AES, the legal key sizes are 128, 192, and 256 bits.

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).
