I purchased the GeoTrust QuickSSL Premium certificate from ssls.com and installed it on my web server which is running Linux Apache on CentOS 6.5.
Google Chrome on Windows 7 said
"The connection is encrypted using AES_256_CBC, with SHA1 for message authentication and ECDHE_RSA as the key exchange mechanism."
The screen shot is as follows.
The certificate path is as follows.
The first part of the certificate details is as follows.
I went to https://knowledge.geotrust.com/support/knowledge-base and it said "Certificate is installed correctly".
I tested my site on www.ssllabs.com/ssltest/analyze.html. It rated my site with an A and said that my signature algorithm is SHA256withRSA. I went to shaaaaaaaaaaaaa.com said
Nice. example.com has a verifiable certificate chain signed with SHA-2.
I went to whynopadlock.com and everything checked out positively.
I set up the intermediate certificate as per the instructions given by GeoTrust.
I went to my web server and added the following to /etc/httpd/conf.d/ssl.conf

It made no difference
