Webb24 juni 2014 · Disable Supported Elliptic Curves Extension from server. 24-Jun-2014 07:33. We see that our F5 load balancer running BIG-IP 11.5.1 Build 2.0.121 Hotfix HF2, is sending the extension for "elliptic curves" (id=10). For example, this is an extract from a debug using the command: $ openssl s_client -tls1 -tlsextdebug -state -debug -connect server ... WebbThe core problem is that if you implement the standard curves, chances are you're doing it wrong : Your implementation produces incorrect results for some rare curve points. Your implementation leaks secret data when the input isn't a curve point. Your implementation leaks secret data through branch timing.
