Yes. My father used to write encryption tools in the 80's. I remember when I was a kid he would tell me how much he got customers complaining that he was overcharging for software. Because it looked like something simple that completed the encryption and decryption really fast. So he added a few useless routines to delay the encryption on a timer just for it to take longer. And magically his costumers stopped complaining about overcharging. Something to always remember when dealing with consumer products.
