There is several SERIOUS errors in the short video that show a severe lack of understanding of how TLS works (I'm sorry for the harsh words).

Let me elaborate:

The lecturer says: "This process is called 'asymmetric encryption' since we're only encrypting the sent message."

This is absolutely wrong. A TLS channel is always "fully encrypted," i.e. encryption happens in both directions. "Asymmetric encryption" is called "asymmetric," because encryption and decryption happens with different keys (public key for encryption, and private key for decryption,) and not with the same key (THIS is why it's called "symmetric encryption", because the encryption and decryption happens using the same key.)

Moreover, the lecturer says: "However, in a microservice architecture, we are going to have services communicating both ways, so traffic must also be encrypted from Service B to Service A. Therefore, when Service A establishes the connection with Service B, it will share a symmetric key, which both services can use to
