Brute forcella kun KRP alkaa cryptaysta purkamaan niin kyllä siinä hetki menee..
The amount of time required to break a 128-bit key is also daunting. Each of the 2128 (340,282,366,920,938,463,463,374,607,431,768,211,456) possibilities must be checked. A device that could check a billion billion keys (10^18) per second would still require about 10^13 years to exhaust the key space. This is a thousand times longer than the age of the universe, which is about 13,000,000,000 (1.3 \times 10^{10}) years.
AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. A device that could check a billion billion (10^18) AES keys per second would require about 3 \times 10^{51} years to exhaust the 256-bit key space.
