Decrypt Session objects?

Stefan

Hi!
I just want to know if it's common to decrypt a Session-Object in a
ASP.NET application.
My collegue says that I have not do this because the information is
stored on the server.
Any suggestions?

Session state is stored on the server side, so you don't need to use any
crypto on it. The actual session id is sent down to the client in the form
of a cookie and re-read on return to the site to actually hook up the user's
Session state with the running code (Page instance).

Session hijacking is always an issue if your network traffic can be
compromised - and on the web it usually can - which is why you have
encrypted viewstate in .NET, and SSL to fall back on should you require it.
However, its not usually something you worry about unless your transactions
are mission critical or financial, then not using enhanced security is a
real foolish thing to do.

Have a read of this, its a very good explanation of your concerns.

ASP.NET Session State Server and garbage collection

by: Frank | last post by:

Our system maintains session state using the ASP.NET State Server service. We expect some of our session state objects to be over 85K, which categorizes them to be VLO's (very large objects) in terms of .NET memory allocations. This means that these objects will be allocated in a special managed heap for large objects. This makes sense since this would require some work for the garbage collector to move and compact these objects during a GC...
