| CryptographicException | The block size is invalid. |
The block size is the basic unit of data that can be encrypted or decrypted in one operation. Messages longer than the block size are handled as successive blocks; messages shorter than the block size must be padded with extra bits to reach the size of a block. Valid block sizes are determined by the symmetric algorithm used.
