What combination of public key cryptography (DH) and symmetric key cryptography is currently available that is (subjectively) as secure as possible over other ciphers (AES,curve448) when security is prioritized over efficiency?

  • $\begingroup$ The term cipher suite suggests you may be talking of TLS or some such protocol. Is this question about TLS, some other protocol, or a general question about Cryptography? $\endgroup$

  • $\begingroup$ Sorry, ciphersuites may not have been the right word. I'm talking about website encrypted communication (https) $\endgroup$

  • $\begingroup$ okay, HTTPS means HTTP over TLS :) $\endgroup$

  • $\begingroup$ you can consult the following site: ciphersuite.info/cs/… You can play around with the TLS version and additional parameters to find what you need. $\endgroup$

    $\begingroup$ No. https by definition is http (which is unencrypted in itself) over a TLS channel. But TLS is one of the most modern, widely adopted and widely implemented protocols probably... so I don't know if I'd worry about that :) $\endgroup$
