This is probably a simple question, but I have this class that I wrote that will be used in the controller that will encrypt some information. I’m just unsure of where to put this class code for the encryption - should it go in one of my models, or should it be in a file all by itself. I just not sure where to put it because it doesn’t seem like it belongs in the controller or models folder. Thanks, -S ---
