> Yes, I know it would be slower, but it might be better to pay the performance cost than to have to move everything to a new algorithm every 20 years. What if your way reveals to be insecure as well in 20 years? Who knows what will happen in that time-frame, it's a long time in our interconnected world. What if instead of trying to find something that works forever, you embrace change and make it easy to change the algorithm instead? So when you need to change in the future (not "if"), you can easily just switch a value to change to the new one. Have solid testing created already for. Don't assume invariants that changes between the different hash functions, like length or what bytes there will be in them.
