Long, long ago in a datacenter far away, breaking 3DES used to be the province of expensive bespoke hardware owned by only the elite nation states. Today it is so trivial that the gpu in your second hand laptop can do it "at scale".
5 years ago ChatGPT was a wet dream.
We should be very conservative in our planning where future security is concerned. The only thing we can be sure of is that Murphy's Law is looking for every chance to make us look foolish.
If you have any link to trivially cracking it on your second hand laptop and doing it at scale, would be very interested.
Of course I can't find the link to whatever I read that discussed gpu accelerated des cracking now.
