body: I've got a little bit of a conundrum. I have created an animation that uses and contains a copyrighted game character model. I want to distribute this animation without breaching copyright. To attempt to do so, I encrypt this animation file with the original game character model file as the key. Only people who own an exact copy of this character model can open the encrypted file, revealing the exact same character model with animation attached. Have I breached copyright? If so, is there a way I could approach this so as to not breach copyright?
  
  
  
title: Is sending a modified encrypted file with the key being the original encrypted file legal?
