http://aes.cryptohack.org/flipping_cookie/ WebMay 20, 2024 · Somebody estimated that if you turned the power of the entire Bitcoin mining network against an AES-128 key, it would take over a hundred times the age of the universe to crack the key. It turns out that there is an attack on AES that’s better than bruteforce, but only slightly – it lowers the security level of AES-128 down to 126.1 bits ...
