- [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 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.…
