we use anonymized access.log
access.log entries look like
[16/Sep/2011:08:28:31 +0200] "<anonymous1>W3hDzSlUsrcfsdRp4FkzjccLzO/xpk7iWmjGl3q1qUk=</anonymous>" .....
How can we de-anonymize selected log file entries, means how can we get username in clear text?
you can decrypt/deanonymize a complete logfile only. In case you want to decrypt only several lines it may be required to put them into a separate log. This file needs to be located on the MWG box itself. On MWG you can find the decryption tool here:
I think there is not (yet) a handy graphical tool available yet so at the moment you will need to manually deanonymize the data.
Let me know if this helps you.
