Can you use both ssl_protocols *and* ssl_cipher_list in the same config (in a way that's sane)?
Is there a way to exclude these ciphers, while still keeping my config easy to parse and avoiding duplicative or deprecated configs?
Yes to both. If you need to support older clients:
ssl_cipher_list = HIGH:!RC4:!MD5:!SRP:!PSK:!aNULL:@STRENGTH ssl_dh_parameters_length = 2048 ssl_parameters_regenerate = 0 ssl_protocols = !SSLv2 !SSLv3 TLSv1 TLSv1.1 TLSv1.2
But why does ssl_protocols behave differently depending on if $ssl_cipher_list is defined? Shouldn't !SSLv2 and !SSLv3 be sufficient?
It seems that if ssl_cipher_list is defined, ssl_protocols = !SSLv2 !SSLv3
results in TLS1.2 being the only one active, but if it is defined, 1.0, 1.1, and 1.2 are all active?
