Which ciphers are enabled in Oracle iPlanet Web Server 7.0 instance? and how do I find information about ciphers that are actually used at run time ?

A lot of people ask me how do I know which ciphers are enabled in Oracle iPlanet Web Server 7.0.

 The list of ciphers and whether they are enabled or disabled is given in the table http://download.oracle.com/docs/cd/E19146-01/821-0794/gcfbv/index.html . This may slightly vary from update release to another.

 The best way to know this is to change <log-level> in server.xml from "info" to "finest" and start the server instance. You will see these log messages at server startup which will tell  you which cipher was enabled or disabled.

Or if you are familir with Admin CLI you can use the following CLI

wadm>list-ciphers --config=<config> --http-listener=<listener> --verbose --all

 For more information refer :

http://docs.oracle.com/cd/E19146-01/821-0792/list-ciphers-1/index.html


Here is my blog about how to use Dtrace to collect information about ciphers used in the connection :

http://blogs.oracle.com/meena/entry/dtarce_script_to_collect_information

You can also modify server.xml to print cipher in access log :

<access-log>
    <file>../logs/access</file>
   <format>%Ses->client.ip% - %Req->vars.auth-user% [%SYSDATE%] "%Req->reqpb.clf-request%" %Req->srvhdrs.clf-status% %Req->srvhdrs.content-length%
%Ses->client.cipher%</format>
</access-log>

Access log will have an new cipher entry in the last column of each row. For example it may show "AES-256","RC4" etc.
