TLS and SSL

“

- [Instructor] Digital certificates allow for the secure exchange of public encryption keys over otherwise untrusted networks. Transport encryption technology, such as Transport Layer Security or TLS, uses those digital certificates to facilitate secure communication over public networks. Let's explore TLS by describing the process that two systems follow when they want to set up an encrypted session that's protected by TLS. First, the client sends a request to the server, asking that the server initiate a secure session. This request includes a list of cipher suites supported by the client. Now it's important to understand that TLS is only a protocol that uses other cryptographic algorithms. TLS is not a cryptographic algorithm itself. Therefore, you can't encrypt something with TLS. You can use TLS to apply other encryption algorithms. The listing of cipher suites sent by the client to the server is a laundry list…
