Apparently, using SecureString with ASP.NET doesn't really make sense because ASP.NET automatically stores request parameters in plain text. But is there a way to hack ASP.NET to make SecureString usable in this scenario?
For example, would it be possible to do something to hook into the ASP.NET pipeline before it has a chance to stash all of the request parameters in memory? Something like a module, but I'm guessing that is too late.
