"a number of Android applications are offering practical solutions that unlock the power of a phone that's really a Unix machine you can slip into your pocket,' Wayner writes".
Except that the iPhone is also "really a UNIX machine you can slip into your pocket.
"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. A device that could check a billion billion (1018) AES keys per second would require about 3×1051 years to exhaust the 256-bit key space."
Steve Jobs reportedly met with Sony prior to the Intel switch and came to the same conclusion. I'm curious what techniques Apple used to quantify the Cell's CPU performance?
Because you can put 8GB of RAM into it. It has 8 DIMM slots, all of which can take a 1GB DIMM. So obviously they've put some support for this in the OS.

It sounds like they are guessing passwords rather than cracking keys. But is there any advantage in using a CELL processor for this?
AES, for example, is the encryption standard used by PGP's whole disk encryption. From
http://en.wikipedia.org/wiki/Brute_force_attack:
"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. A device that could check a billion billion (1018) AES keys per second would require about 3×1051 years to exhaust the 256-bit key space."
Hence my thought that they are not cracking keys.
Don't forget dtrace. OS X has a nice interface on top of dtrace called Instruments.

By the way, even though it is a 64-bit CPU, it has a 42-bit physical address space:
