00:00.420 --> 00:06.650
Let's take a deeper look at encryption technologies what does symmetric encryption actually mean.

00:06.660 --> 00:13.270
Most important symmetric encryption means that encryption and decryption use the same secret key.

00:13.320 --> 00:19.020
The big advantage in practice of symmetric encryption is that it's very fast.

00:19.020 --> 00:25.820
The biggest problem of this kind of encryption is that exchanging the plain secret key is very hard.

00:25.830 --> 00:32.660
It cannot simply be transmitted over a secure network because then anybody has access to this key.

00:32.850 --> 00:40.440
Then there is as symmetric encryption also known as Puplick key encryption here the encryption and decryption
