Joshua Tauberer cc7be13098 update nginx cipher list to Mozilla's current intermediate ciphers and update HSTS header to be six months
* The Mozilla recommendations must have been updated in the last few years.
* The HSTS header must have >=6 months to get an A+ at ssllabs.com/ssltest.

Joshua Tauberer f046031b26 nginx-ssl.conf changes were partially incorrect, partial revert of 834c42bc50
My own /etc/nginx/nginx.conf was messed up, so what I thought were Ubuntu 14.04 defaults weren't, and we lost the ssl_protocols and ssl_prefer_server_ciphers settings. This puts those back.

Joshua Tauberer 834c42bc50 move nginx-ssl to be a global configuration file rather than including it into each server block 2015-09-27 17:13:11 +00:00
Joshua Tauberer 93c2258d23 let the HSTS header be controlled by the management daemon so some domains can choose to enable preload 2015-09-08 21:20:50 +00:00

Joshua Tauberer 47de93961e OCSP improvements
* Set ssl_stapling_verify to off per https://sslmate.com/blog/post/ocsp_stapling_in_apache_and_nginx ('on' has no security benefits).
* Set resolver to 127.0.0.1, instead of Google Public DNS, because we might as well use our local nameserver anyway.
* Remove the commented line which per the link above would never be necessary anyway.

OCSP seems to work just fine after these changes.

Joshua Tauberer 39bca053ed add 2048 bits of DH params for nginx, postfix, dovecot
nginx/postfix use a new pre-generated dh2048.pem file. dovecot generates the bits on its own.

ssllabs.com reports that TLS_DHE ciphers went from 1024 to 2048 bits as expected. The ECDHE ciphers remain at 256 bits --- no idea what that really means. (This tests nginx only. I haven't tested postfix/dovecot.)
