There is an exception, you can only use that directive in server config, that's why I asked about the context.

If you set that up inside a virtualhost, it will probably will give you issues.

Daniel,

 

Thanks for the response.  I am running OpenSSL 0.9.8.  I am attempting to secure TLS compression and mitigate the CRIME vulnerability by adding the following directive to the httpd.conf file:

 

Implementation on Apache HTTP Server (mod_ssl)

The following configuration block can be used in Apache HTTP Server 2.2+/2.4+ with mod_ssl. However, there is an exception of being able to turn off TLS/SSL Compression as this is only possible Apache HTTP Server 2.2.24/2.4.3+ using the SSLCompression directive.

 

SSLProtocol ALL -SSLv2 -SSLv3

SSLHonorCipherOrder On

SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5

SSLCompression Off

I am

Hello Everyone,

 

I have Apache 2.2.24 installed and I am attempting to disable compression.  I am editing the httpd.conf file and adding ‘SSLCompression Off’.  When I do that, the Apache service does not start.  The system log does not register any meaningful error.  Has anyone encountered this before?

 

Thanks…

In which context are you trying to use it? Which openssl version do you use?
