How to add SSL_RSA to SSLCipherSuite?

Really hope for some help in my problem with SSLCipherSuite... So i have this kind of virtualhost config:

<VirtualHost *:443>
DocumentRoot /home/webz/site.com
ServerName site.com
ServerAlias www.site.com

SSLProtocol -all +TLSv1.1 +TLSv1.2

SSLHonorCipherOrder on
SSLCipherSuite "kEDH:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+AESGCM:EECDH:EDH+AESGCM:EDH+aRSA:HIGH:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!DHE-RSA-SEED-SHA:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA:!DH+3DES:!DHE-RSA-AES256-GCM-SHA384:!DHE-RSA-AES256-SHA256:!DHE-RSA-AES256-SHA:!DHE-RSA-CAMELLIA256-SHA:!DHE-RSA-DES-CBC3-SHA:!DHE-RSA-AES128-GCM-SHA256:!DHE-RSA-AES128-SHA256:!DHE-RSA-AES128-SHA:!DHE-RSA-CAMELLIA128-SHA:!RC4"
SSLCompression off

SSLEngine on
SSLCertificateFile /etc/httpd/ssl/site.com.crt
SSLCertificateKeyFile /etc/httpd/ssl/site.com.key
SSLCertificateChainFile /etc/httpd/ssl/DigiCertCA.crt
</VirtualHost>

Everything works fine also security is ok by test. (https://cryptoreport.websecurity.symantec.com/checker/views/certCheck.jsp)

PROBLEM: I am trying to install payment module (REDSYS) for Opencart 2. Redsys support team are not activating payment module because they ask me to add one off SSLCipherSuite below:

SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, SSL_RSA_WITH_AES_128_CBC_SHA, SSL_RSA_WITH_AES_256_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_RSA_FIPS_WITH_3DES_EDE_CBC_SHA

At the moment all SSLCipherSuite starts with TLS... :( So how to add one of those SSLCipherSuites with SSL_RSA... ??? Hope there is somebody who knows good SSL and will help...

According to your configuration you have such cipher suites already. For example you've included AES256-SHA which is the same as TLS_RSA_WITH_AES_256_CBC_SHA. And the SSL_ prefix instead of the TLS_ prefix is just a convention from the old times where TLS was called SSL (i.e. TLS 1.0 is in effect SSL 3.1).

It is more likely that your restriction to TLS 1.1 and TLS 1.2 causes the problem, because given that they require you to use such old ciphers and cannot even handle ECDHE ciphers might indicate that they have a very old client which is not able to speak TLS 1.1 or TLS 1.2.

Of course it might also be that you've included different ciphers in other (i.e. not shown) parts of your server configuration which take precedence. To get information what kind of ciphers your server really supports check your site with SSLLabs.

EDIT: The analysis by SSLLabs shows quite clearly that TLS_RSA_WITH_AES_256_CBC_SHA (which is the same as SSL_RSA_WITH_AES_256_CBC_SHA or AES256-SHA) is enabled on the server as requested. If my assumption is correct the real problem is that they use an old client which does not speak TLS 1.1 or TLS 1.2 yet. In this case you could change your configuration for the supported protocol versions to allow TLS 1.0 too:

SSLProtocol all -SSLv3

With this configuration TLS 1.0 and better (i.e. TLS 1.1, TLS 1.2) are supported.
