"IDEA's key length is 128 bits - over twice as long as DES.
Assuming that a brute force attack is the most efficient,
it would require 2^128 (10^38) encryptions to recover the
key. Design a chip that can test a billion keys per
second an throw a billion of the them at the problem,
and it will still take 10^13 years - that's longer than
the age of the universe. An array of 10^24 such chips can
find the key in a day, but there aren't enough silicon
atoms in the universe to build such a machine. Now we're
getting somewhere - although I'd keep my eye on the dark
matter debate."
