I have a routine that uses a hidden frame for displaying certain information based on an access code the user enters. All the relative data is contained within a 2d array. The problem is that this file is loaded and visible in the cache after the files are accessed. I would like to know a simple encrypt/decrypt method so that at least the array information is not readily viewable from a text editor. I know this method could be easily decoded with a little effort, but I want to keep it away from the basic user.
