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 certificates to facilitate secure communication over those public networks. In this video, learn about the role of TLS in protecting data and how it uses both public and session keys. Also, learn the importance of choosing strong TLS cipher suites.
- [Instructor] Digital certificates allow…for the secure exchange of public encryption keys…over otherwise untrusted networks.…Transport encryption technologies…such as Transport Layer Security or TLS,…uses those certificates to facilitate secure…communication over those same public networks.…Let's explore TLS by describing the process…that two systems follow when they wish to set up…an encrypted session protected by TLS.…First, the client sends a request to the server…asking the server initiate a secure session.…
This request includes a list of the cipher suites…supported by the client.…It's important to understand that TLS…is only a protocol that uses other cryptic…graphic algorithms.…TLS is not a cryptic graphic 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…of the encryption algorithms, hash functions…and other cryptographic details that the client understands.…
