Persze, minden feltorheto, csak kerdes, hogy mennyi ido alatt ;)
"As shown above, even with a supercomputer, it would take 1 billion billion years to crack the 128-bit AES key using brute force attack."
"If you assume:
Every person on the planet owns 10 computers.
There are 7 billion people on the planet.
Each of these computers can test 1 billion key combinations per second.
On average, you can crack the key after testing 50% of the possibilities.
Then the earth's population can crack one encryption key in 77,000,000,000,000,000,000,000,000 years!" - http://www.eetimes.com/design/embedded-internet-design/4372428/How-secure-is-AES-against-brute-force-attacks-
