Objet: RE: Block size using AES-192

The problem is that in the specific case of AES-192, my key has a length of
24 bytes, the block length is a multiple of 24, but the program crashes
because BlockSize() returns 16 instead of 24, which I don't understand. This
happens both in ECB and CBC (non CTS) modes.
