Is it true that the SSL certificate on the site encrypts ClSrv traffic?

Question

Information Security

Is it true that an SSL certificate, due to encryption, blocks the ability of the provider to listen to the user's traffic?

Answer 1

I don't know what you mean by CLSrv traffic.
Therefore, I will simply give a link to a description of how SSL works.
In short, based on an SSL certificate, the client and server generate session keys that further encrypt application traffic. However, the use of an SSL certificate in any particular application implementation may differ or be incomplete.
