What exactly are each of "Curves" and "ECDHParameters" used for, as documented by https://www.openssl.org/docs/man1.0.2/ssl/SSL_CONF_cmd.html? My understanding of elliptic curves in TLS is that they're used in two places: as ECDSA key pairs used in certificates, and in ECDHE for key exchange. (Are there more uses I'm not aware of?) I know the curve used for ECDSA is a property of the key pair associated with the certificate, so it doesn't make sense to be a setting controlled at runtime. My best guess is that the curve for ECDHE is controlled by ECDHParameters. Given all of this, I can't figure out what's left for the "Curves" parameter to control. Are my above assumptions right? If so, what does "Curves" control? Joseph C. Sible -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
