keys are quite a lot to check (although, if all the atoms in the |
11 |
universe [estimated 10^78] were to test 1 key/sec, it'd only take about |
12 |
0.1157920892 seconds). However.. 512 bit keys with all the atoms testing |
13 |
a trillion keys/second would take about |
14 |
(2^512)/(10^78)/60/60/24/(36525/100)/(10^12) or 4.2486779507765473608e56 |

I submit that brute forcing an AES key of reasonably length is |
18 |
currently impossible in an amount of time that would matter to the human |
19 |
race. |
