[[https://www.psw.net]]

===== Apache configuration =====

mhost.conf or corresponding subdomain under sites-enabled:

<code text>
NameVirtualHost your.server.ip.here:443
...
    SSLEngine on
    SSLCertificateKeyFile /etc/ssl.key/name.of.key
    SSLCertificateFile /etc/ssl.crt/name.of.crt
    SSLCertificateChainFile /etc/ssl.crt/name.of.ca-bundle

    SSLHonorCipherOrder On
    SSLCipherSuite ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH

The SSL module may still need to be activated in Apache:

<code bash>
a2enmod ssl
</code>

Now restart and it should work:

<code bash>
/etc/init.d/apache2 restart
