encryption - How do I ensure that openssl is using AES-NI acceleration? - Ask Ubuntu

i running ubuntu 16.04.1 lts, checked processor support aes-ni acceleration on cpus:

johndoe@mycomputer:~$ grep -m1 -o aes /proc/cpuinfo aes johndoe@mycomputer:~$ grep -o aes /proc/cpuinfo | wc -l 4 johndoe@mycomputer:~$ lscpu | grep '^cpu(s):' cpu(s):                4 

how can check openssl using aes-ni?

thank you, luckyrings

i found answer myself.

to test if openssl using aes-ni found following information. can't see after compiling aes-ni available openssl, can perform performance tests , without feature.

speed test default settings:

openssl speed -elapsed -evp aes-128-cbc 

speed test explicit disabled aes-ni feature:

openssl_ia32cap="~0x200000200000000" openssl speed -elapsed -evp aes-128-cbc 

the result first line run faster (almost double on i7 cpu). conclusion aes-ni used default openssl.
