How to find whether your Mac's processor supports AES ( Advanced Encryption Standard) specification or not ?

To find out whether the processor on the  Mac is capable of supporting AES ( Advanced Encryption Standard specifications ) or not ,  we can run the following command to know the status 
$ sysctl -a | grep aes
The output might be : hw.optional.aes: 0
OR 
hw.optional.aes:1
If  "hw.optional.aes:" value is 0 then the processor does not support AES . If value is 1 then processor supports AES.

You also can check the features supported by the processor on the intel site at : http://ark.intel.com/  by supplying the processor model number. Processor model number can be found by running following command.

$ sysctl -a | grep machdep.cpu.brand_string
output :  machdep.cpu.brand_string: Intel(R) Core(TM)2 Duo CPU     P8800  @ 2.66GHz
