== Usage ==
To use AES NI you need to load the aesni_intel kernel module.
$ /sbin/modinfo aesni_intel
filename: /lib/modules/3.0.0-13-generic/kernel/arch/x86/crypto/aesni-intel.ko
alias: aes
license: GPL
description: Rijndael (AES) Cipher Algorithm, Intel AES-NI instructions optimized
srcversion: 61A51F44F192D7CE0FBA795
depends: cryptd,aes-x86_64
vermagic: 3.0.0-13-generic SMP mod_unload modversions

To see if your CPU supports AES NI check the output of "cat /proc/cpuinfo | grep aes"
$ cat /proc/cpuinfo | grep aes | wc -l
4

To check whether or not AES NI is enabled check the contents of /proc/crypto
$ grep module /proc/crypto | sort -u
module : aesni_intel
module : aes_x86_64
module : arc4
module : kernel

To see if OpenSSL supports AES-NI run openssl engine
$ openssl engine
(aesni) Intel AES-NI engine
(dynamic) Dynamic engine loading support
