Now we want to take a more deeper look into the technology what are parameters of the symmetric encryption.

00:08.420 --> 00:15.290
First of all there's the Scifres or algorithms block length asymmetric encryption algorithm is designed

00:15.290 --> 00:19.820
to encrypt a certain block of data with a specific length.

00:19.820 --> 00:25.430
For instance 16 bytes or 128 bits for a years.

00:25.640 --> 00:33.700
So a symmetric cipher is mathematically or cryptographically designed for exactly this block links only

00:34.730 --> 00:39.400
Next there is the block cipher mode or mode of operation.
