Hello,

From within DNN, I want to add a link that will open a new website in a popup window.  The catch is that I want to include the currently signed-in DNN user's email address (encrypted) in the query string so that the destination website can automatically login that user without them having to type a login/password.

I control both the DNN portal site and the destination website (ASP.NET).  I'm just not sure how to accomplish this from within DNN - do I need to write a custom module? 

Thanks in advance

To encrypt the email address for sending, you will need to use a custom module.

You will then just want to implement an encryption scheme that can be shared between the two applications.

Overall, a very simple development task.
