Intel AES New Instructions (AESNI) libraries for C on Ubuntu

First, you need to check if your CPU is compatible with hardware accelerated Intel technology for cipher/decrypt with AES.

Next, we need to download the Intel AESNI library and compile it:

wget https://software.intel.com/sites/default/files/article/181731/intel-aesni-sample-library-v1.2.zip
unzip intel-aesni-sample-library-v1.2.zip
cd Intel_AESNI_Sample_Library_v1.2
./mk_lnx64_all.sh

Maybe, you will get the following errror:

collect2: error: ld returned 1 exit status
Got error on link

If you get it, please install yasm

sudo apt-get install yasm

Now, compile it again:

./mk_lnx64.sh     

~/Downloads/Intel_AESNI_Sample_Library_v1.2/aes_example ~/Downloads/Intel_AESNI_Sample_Library_v1.2/aes_example

~/Downloads/Intel_AESNI_Sample_Library_v1.2/intel_aes_lib ~/Downloads/Intel_AESNI_Sample_Library_v1.2/intel_aes_lib

do iaesx64.s

do do_rdtsc.s

~/Downloads/Intel_AESNI_Sample_Library_v1.2/intel_aes_lib

~/Downloads/Intel_AESNI_Sample_Library_v1.2/aes_example

mkdir: cannot create directory ‘bin’: File exists

src/aes_example.c: In function ‘main’:

src/aes_example.c:2327:10: warning: too many arguments for format [-Wformat-extra-args]

   printf("input_file (will be overwritten)= %s encoded_file= %s, decoded_file= %s\n",

          ^

created bin/aes_example64

Now, you can run bin/aes_example64 

Enjoy it!

If you want more examples remember that AESNI use the following libraries:

#include "iaesni.h"

#include "iaes_asm_interface.h"
