I'm looking for a quick and easy method of obfuscation
querystring values to prevent courious users from
wondering around my database.  Although this event may
be unlikely, I just want the values to be
indescernable. (I'm dealing with highschool students
here!)  Under other cirsumstances I would use a hidden
field value but in this case I need it in a href value
in a datagrid and I can't see other ways around it. 
Any assistance would be greatly apprecated! :D
