There was an interesting question on the forums at asp.net about how to encrypt a Database string in DotNetNuke the other days. Bipin Joshi has written a fair inclusive tutorial on how to do this with Asp.Net 2.0. While its is not specifically for DotNetNuke, you should be able to ascertain the steps needed to encrypt your connection strings. Perhaps the core team could look at Bipin’s code and use it as a roadmap to include this much needed feature in DotNetNuke.
