Setting a Key Mode and Padding

You can set the key mode and padding for a symmetric key (AES or DESede).

To set the key padding:

key.Padding = PaddingMode.PKCS7;

To set the key mode:

key.Mode = CipherMode.CBC;

These values are stored until the program exits. Whenever you access the key, the values stored in the memory are used, unless you override them.
