Hi, I'm struggeling with enabling SSL forward secrecy in my haproxy 1.7 setup.
So far the global settings look like: tune.ssl.default-dh-param 2048 # tune shared secred to 2048bits ssl-default-bind-options force-tlsv12 no-sslv3 ssl-default-bind-ciphers TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA:TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA:AES256+EECDH:AES256+EDH:TLSv1+HIGH:!aNULL:!eNULL:!3DES:!RC4:!CAMELLIA:!DH:!kECDHE:@STRENGTH:!DHE ssl-default-server-options force-tlsv12 no-sslv3 ssl-default-server-ciphers TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA:TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA:AES256+EECDH:AES256+EDH:TLSv1+HIGH:!aNULL:!eNULL:!3DES:!RC4:!CAMELLIA:!DH:!kECDHE:@STRENGTH:!DHE ssl-server-verify required tune.ssl.cachesize 100000 tune.ssl.lifetime 600 tune.ssl.maxrecord 1460 and in my https UI I've set: ### ssl forward secrecy tweak # Distinguish between secure and insecure requests acl secure dst_port eq 443 # Mark all cookies as secure if sent over SSL rsprep ^Set-Cookie:\ (.*) Set-Cookie:\ \1;\ Secure if secure # Add the HSTS header with a 1 year max-age rspadd Strict-Transport-Security:\ max-age=31536000 if secure Still Qualys gives me an A- rating telling me: The server does not support Forward Secrecy with the reference browsers. Grade reduced to A-. Any clue how to fix this? * Julian Wichtiger Hinweis: Der Inhalt dieser E-Mail ist vertraulich und ausschlie?lich f?r den bezeichneten Adressaten bestimmt.
