AES-NI in Macbook Pro laptops

If you have a Macbook Pro with a Core i5 or i7 you _may_ have AES-NI, which make AES encryption much faster.

Read about it here en.wikipedia.org/wiki/AES_instruction_set and check for CPU availability here ark.intel.com/MySearch.aspx?AESTech=true.

Not all Core CPUs have AES-NI. Here's Anandtech's page that summarises for 15" MBPs.

useful. The new Mac Airs seem to have AES acceleration as well.
