can you spare a minute?
About 128bit encryption keys:
“Complexities are expressed as orders of magnitude. If an algorithm has a processing complexity of 2^{128}, then 2^{128} operations are required to break the algorithm. (These operations may be complex and timeconsuming).
Still, if you assume that you have enough computing speed to perform a million operations every second and you set a million parallel processors against the task, it will still take over 10^{9} years to recover the key. That’s a billion times the age of the universe.”
Impressive? Yes. But there’s a flaw on this theory: technology is not constant over time. More processing power together with brains writting more efficient cracking algorithms is all that will take to get 128bit keys breakable during my life time. And that’s what I call impressive.
