Manually specify cipher suite
To secure the transfer of data, TLS/SSL uses one or more cipher suites. A cipher suite is a combination of authentication, encryption, and message authentication code (MAC) algorithms. They are used during the negotiation of security settings for a TLS/SSL connection and the transfer of data.
Depending on context, the need to support legacy browsers and regulatory requirements, you can choose different cipher suite configurations (modern, intermediate, or old).
TLS 1.3 does not require manually specifying cipher suites.
