Encrypt the $remote_addr in log files

Hi, I want to give the user of my websites more privacy. Well – I just
need the logs for debugging and some statistics. So I don’t need to save
the real users IP address, but I need some kind of identifier string to
separate users (like I do with IP addresses now). My idea is to just run
md5 on the IP address, so I get a unique string for every IP address.

On the http://wiki.nginx.org/NginxHttpLogModule LogModule page in the
Nginx Wiki I couldn’t find all variables, I can use in the log files. So
is there a build in feature to encrypt the IP address or do I have to
write my own (small) module to get this feature?

You can use built-in perl to hash variables.

In log files you may use all variables from all modules. But
there is no one with md5 of $remote_addr.

With embedded perl module you may use perl_set to produce
apropriate variable. Though it would be probably better to write
simple module instead if you don’t already have embedded perl in
your nginx for other reasons.
