Thank you. With the setting below in httpd.conf |
| 2 |
|
| 3 |
SSLProtocol all -SSLv2 -SSLv3 |
| 4 |
SSLCipherSuite |
| 5 |
EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aRSA:DES-CBC3-SHA:!RC4:!ECDHE-RSA-DES-CBC3-SHA:!aNULL:!eNULL:!LOW:3DES:!MD5:!EXP:!PSK:!SRP:!DSS |

and in vhosts.conf with: |
| 8 |
NameVirtualHost *:443 |
| 9 |
... |
| 10 |
Header set Strict-Transport-Security "max-age=31536000; includeSubDomains" |
| 11 |
... |
| 12 |
|
| 13 |
I get "A+" rating, so I think should be OK |
| 14 |
|
| 15 |
Certificate 100 |
| 16 |
Protocol Support 95 |
| 17 |
Key Exchange 80 |
| 18 |
Cipher Strength 90 |
