SSLOpenSSLConfCmd Curves

The SSLOpenSSLConfCmd is only available on httpd 2.4.8 later. However, you may still generate and use your own DH params on earlier versions, as explained well here : If you are using Apache with LibreSSL, or Apache 2.4.7 and OpenSSL 0.9.8a or later, you can append the DHparams you generated earlier to the end of your certificate file just make them : separated SSLOpenSSLConfCmd Curves secp384r1:secp521r1 - hackajar Dec 11 '15 at 3:41 Unfortunately SSLOpenSSLConfCmd is not supported in Apache 2.4.7, which is the version packaged with Ubuntu 14.04 LTS

  1. Some of the SSLOpenSSLConfCmd commands can be used as an alternative to existing directives (such as SSLCipherSuite or SSLProtocol), though it should be noted that the syntax / allowable values for the parameters may sometimes differ

  6. Aktuell wird der Webserver Apache2 unter Ubuntu 18.04 mit der Versionsnummer 2.4.29 ausgeliefert. Durch die Installation von KeyHelp und der Verwendung Let's Encrypt wird auch das Modul SSL des Apache2 installiert und aktiviert. Standardmäßig sind natürlich SSL Protokolle wie TLS 1.0, TLS 1.1 und TLS 1.2 aktiviert
  7. To ensure the new one is used going forward I took the following steps... Created /etc/ld.so/conf.d/openssl.conf with /usr/local/openssl/lib as the content, then ran ldconfig -v to update it. Created /etc/profile.d/openssl.sh with the following content... and ran source /etc/profile.d/openssl.sh to update it

I found out, that (at least Chrome, read more on this topic here), decided to go for lower Key Exchange negotiation, namely P-256 (prime256v1 in Apache2, though SSL Labs reports it like secp256r1) in spite of me having set the above curves. So, I guess we should add P-256 to the list.

The discrete log algorithms we used to attack standard Diffie-Hellman groups do not gain as strong of an advantage from precomputation, and individual servers do not need to generate unique elliptic curves.
