Security Keys

As of WordPress 2.7, there are four security keys available that are designed to insure better cookie encryption. These keys work silently in the background and should be as random and complicated as possible (no, you will never need to remember them). The easiest way to generate these keys is to do it automatically at the WordPress.org secret-key service. Simply visit that link and copy/paste the results into your wp-config.php file. Note that these keys may be changed anytime, and doing so will invalidate all of your users’ existing cookies so that they will have to re-login to your site.
