C# .NET to Silverlight Class

I have a c# class I can give you the entire class to work with at some point after I select a worker. The class is encryption and it uses three encrytion options. I need them converted to a silverlight class. The existing code works in .NET for ASP, WInforms etc but I need a version to work in silverlight.
