Relying on scale to declare something so difficult it is impossible,
thus evading the moral question of whether the act is permissible.
And I think you might have twelve too many zeroes on the bottom line.

Would you figure on 148 days?
I've got to run - but I'll also dig
up one of the cryptographic machanisms commonly used with 128 that is now
breakable in a few hours.
As the other poster pointed out:
What does
any of that have to do with the moral question presented of an invasion of
privacy?

Obviously this speaks to one method of encryption and
does not equally apply to all.
The bottom line point is:
Just because
something would take the life of the universe to brute force doesn't mean it
can't be cracked in far less time using math techniques.
Again:
This
has nothing whatsoever to do with Joe deliberately, knowingly accessing
information he is not entitled to!

Let's do the math in a different direction - just for fun.
Total
combination 2128 = 3.4E+38
Time frame to brute force all: 5
years = 157,788,000 seconds
Processing per second:
2.15658E+30
Assuming Moore's Law holds true as applied to supercomputers
(doubles approx. every two years), how many years would it be before a
supercomputer was built that could process that many transactions per
second?
Current record holder is Oakridge National Labs with a
whopping 17.59 petaflops (1015).
Taking 17.59 petaflops and
dropping it into a spreadsheet, doubling it for the next column and so on puts
us in processing range in 94 years :)
So there's my estimate based on
Moore's Law.
In 94 years we'll be able to brute force a 128 bit key in a 5
year period.
In 148 years, we'll be able to brute force the 128 bit key
in 1 second.
:)
Hmm... maybe 150 years isn't really so long in
the context of society's lifespan as opposed to an individual's
lifespan.
