69 = 103.5 years Note that it is extremely unlikely that Moore’s Law will be valid for such a time period! Thus, a 128 bit key seems impossible to brute-force, even in the foreseeable future.

365days/1day i = 68.42 We round this number up to 69 assuming the number of Moore iterations is discreet.

Let i be the number of Moore iterations needed to bring the search time down to 24h: 1.08

1018years That is about 108 = 100, 000, 000 times longer than the age of the universe.1012 keys/sec On average, we have to check (2127 keys: (2127 keys)/(5.

Thus, 1 million dollars buy us 10,000 engines. 1.3 One search engine costs $ 100 including overhead. Shoshin Nagamine, further reading: The Essence of Okinawan Karate-Do by Shoshin Nagamine, Tuttle Publishing, 1998. I offer my theories in the hope that the essence of Okinawan karate will remain intact. I do not deem myself the final authority, but my experience with kata has left no doubt that the following is the proper application and interpretation.

It is not an easy task to explain each movement and its significance, and some must remain unexplained. Because the practice of the basic movements of kata is the focus and mastery of self is the essence of Matsubayashi Ryu karate do, I shall try to elucidate the movements of the kata according to my interpretation based on forty years of study.
