For those people who are using BlogEngine.net and would like to have the ability to encrypt their web.config file and decrypt it easily.  Chris Blankenship has written an excellent add-in for us that allows us to do just that.  You can read his post about the modification Encrypt Web.Config Extension for BlogEngine.Net.

Basically the modification needs two files added to the admin section of the site and a simple modification of the web.sitemap file to add the files to the admin section of BlogEngine.  I think it's a great feature for use when your hosting your web site on a hosting service and would like to keep all your passwords kept secret.
