DO NOT REPLY [Bug 51958] New: mod_ssl documentation is confusing re. SSLCipherSuite Directive

https://issues.apache.org/bugzilla/show_bug.cgi?id=51958

             Bug #: 51958
           Summary: mod_ssl documentation is confusing re. SSLCipherSuite
                    Directive
           Product: Apache httpd-2
           Version: 2.2-HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Documentation
        AssignedTo: docs@httpd.apache.org
        ReportedBy: advax@triumf.ca
    Classification: Unclassified


In the Apache documentation
http://httpd.apache.org/docs/2.2/mod/mod_ssl.html#sslciphersuite
there is an example:

$ openssl ciphers -v 'ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP'
NULL-SHA                SSLv3 Kx=RSA      Au=RSA  Enc=None      Mac=SHA1
...

Using this command on Linux, the NULL ciphers are suppressed so that NULL-SHA
is not listed.


The page also states:

The default cipher-spec string is
``ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP'' which means the following:
first, remove from consideration any ciphers that do not authenticate, ...
Next, use ciphers using RC4 and RSA. "

I interpret this to mean that ciphers using RC4 are first in the list. But in
fact, these ciphers are already included in ALL, and are not first. The
presence of RC4+RSA in the cipher string has no effect at all.


using openssl-0.9.8e on RHEL5.2

That particular part of the documentation is ca 10 years old. Might be time to
update it.

Created attachment 28572
  --> https://issues.apache.org/bugzilla/attachment.cgi?id=28572
proposed patch for very outdated SSLCipherSuite doc

use pquerna's CipherSuite as example. Explain what it does.

I just realized that the discussion we had in #httpd-dev hasn't been transfered
over here.

Let's see if I can remotely remember it:

The docs on this are 10 y/o. Back then, OpenSSL 0.9.6e was new and hot. Since
then the behaviour of this output has changed, a lot.

We should replace the output with what a current version of OpenSSL provides,
so as not to confuse people.
