Mediawiki/Anonymous IP Hash

Here's the gist of my anon ID hack to MediaWiki. I can't really package it as an extension or anything because it involves hacking things that apparently aren't supposed to be hacked, but it's not hard to do. - Halcy

1. Add the following to your LocalSettings.php:

// you can leave anon talk pages on, but you'll
// likely end up with useless crud after IDs expire
$wgDisableAnonTalk = true;
function AnonUsername() {
        # dmY = new ID per day, WY = per week
        $key = wfGetIP().'PUT RANDOM TEXT HERE'.gmdate('dmY');
        return 'ID:'.substr(crypt(md5($key), 'id'), 2, 8);
}

Warning: Consider using something better than md5, such as sha1 for same performance, or bcrypt for reduced brute force.

Note: Obviously you'd change the "PUT RANDOM TEXT HERE" to some random text: this functions as the salt and reduces the risk of brute force attacks. Just bang on the keyboard for a bit, or if you want to be truly random, get an RNG or just roll some dice.

2. In includes/user/User.php, find the line that says

   $this->mName = IP::sanitizeIP( wfGetIP() );

... and change it to ...

   $this->mName = AnonUsername();

On a slightly related note, I hacked an extension together for <aa> tags.
