[SGVLUG] for crypto freaks

[Don Gibbs]

"... 2^128 is a very big number. ...

Imagine a computer that is the size of a grain of sand that can test 
keys against some encrypted data. Also imagine that it can test a key 
in the amount of time it takes light to cross it. Then consider a 
cluster of these computers, so many that if you covered the earth 
with them, they would cover the whole planet to the height of 1 
meter. The cluster of computers would crack a 128-bit key on average 
in 1,000 years."

Cute imagery.  I wonder how true it is.
