Re: apache 2.4.10 sslv3 not offering when tls is enabled (Apache Users)

Hi,

First off all Thanks , like already said I tried about everything :-( nevertheless i tried all of them again ... without success.

I cannot get the server to offer SSLV3 when TLS is enabled (Any TLS ) when I do ssl protocol SSLv3 then sslv3 works but from the moment I add TLS , SSLv3 no longer works

Sven

Your SSL config for Apache 2.4.10 should be as follows

<VirtualHost *:443>
...
SSLEngine on
SSLCertificateFile /path/to/signed_certificate_followed_by_intermediate_certs
SSLCertificateKeyFile /path/to/private/key

# Uncomment the following directive when using client certificate authentication
#SSLCACertificateFile /path/to/ca_certs_for_client_authentication

# HSTS (mod_headers is required) (15768000 seconds = 6 months)
Header always set Strict-Transport-Security "max-age=15768000"
...
</VirtualHost>

# intermediate configuration, tweak to your needs
SSLProtocol all -SSLv3
SSLCipherSuite ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS

And, please, for the love of god, add these, too:

SSLHonorServerOrder On
SSLCipherSuite TLSv1.2:TLSv1.1:TLSv1:SSLv3

This will cause "better" ciphers to be preferred over the lesser ones.
Don't forget to eliminate the insecure ones like EXPORT, MD5, DES,
RC4, etc.

A typical cipher string I might use looks like this:

SSLCipherSuite
!aNULL:!eNULL:!EXPORT:!DSS:!DES:!SSLv2:!RC4:ECDHE:ECDH:DHE:AES256-GCM-SH
A384:AES128-GCM-SHA256:HIGH
