- fix Logjam vulnerability (follows the https://weakdh.org/sysadmin.html guide) Change SSLCipherSuite cipherstring to disable export cipher suites and deploy Ephemeral Elliptic-Curve Diffie-Hellman (ECDHE) ciphers. Adjust 'gensslcert' script to generate a strong and unique Diffie Hellman Group and append it to the server certificate file [bnc#931723], [CVE-2015-4000] OBS-URL: https://build.opensuse.org/request/show/321967 OBS-URL: https://build.opensuse.org/package/show/Apache/apache2?expand=0&rev=458
