Key recovery attacks will only take a 1/4 billion years much better than the 1 billion years right .. still your great great great (x8) grand child will be dust. Your option is going to be prayer and bruteforce https://hackforums.net/showthread.php?tid=5912770 (Nov 29, 2018 02:51 PM)CyberStrike Wrote: Hmm what .. exploits against 128 AES?
