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. Learn the role of TLS in protecting data and how it uses both public and session keys. You will also learn the importance of choosing strong TLS cipher suites.
- [Narrator] 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 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 that 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 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 of the encryption algorithms,…hash functions, and other cryptographic details…that the client understands.…
