did we have supercomputer with speed of 1 nonillion calculation/second [on hold]

so im trying to create product that use secret code that generated randomly, im start with 20 random string uppercase lowercase and number. and use http://ift.tt/17tNa2h to test it. and i found that if you have computer with, 1 nonillion(1,000,000,000,000,000,000,000,000,000,000) calculation per second you can break the code in 8 days. quastion: are we have supercomputer that capable of doing 1nonillion callculation/second...????
