Weak Diffie-Hellman and the Logjam Attack

Postby maurice1471270175 » Mon Aug 15, 2016 4:28 pm

Hi,

Is there someone who has experience with implementing/configuring tomcat against; Diffie-Hellman and the Logjam Attack https://weakdh.org/ https://weakdh.org/sysadmin.html
There is a section "Apache Tomcat" (2nd URL) which describes what ciphers to add in the server.xml but i really don't have a clue what to do with the dhparams.pem generated in the first step and how to implement it in tomcat/keystore?

Any ideas?

Thanks...

I installed Nginx as reverse proxy in front of the application server and put all security in there. I also use this to block the /servoy-admin and /servoy-client pages for the public access.
